作者:互联网

参考 micro-oauth2原文博客

redis环境准备

下载

解压

把redis-server.exe的路径加到系统的环境变量path里

启动服务

redis-server.exe redis.windows.conf

连接服务

redis-cli.exe -h 127.0.0.1 -p 6379

注意有时候会有中文乱码,要在 redis-cli 后面加上 --raw:

redis-cli --raw

退出quit:

启动脚本

@echo off
F:
cd F:\Redis
redis-server.exe redis.windows.conf 
exit

放在redis安装目录:

为该脚本创建快捷方式,点击即可运行。

添加认证服务模块

Oauth2认证服务,负责对登录用户进行认证,整合Spring Security + Oauth2。

在pom中添加相关依赖

主要是Spring Security、Oauth2、JWT、Redis相关依赖:

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-security</artifactId>
    </dependency>
    <!--nacos客户端-->
    <dependency>
        <groupId>com.alibaba.cloud</groupId>
        <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
    </dependency>
    <!-- https://mvnrepository.com/artifact/org.springframework.cloud/spring-cloud-starter-oauth2 -->
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-oauth2</artifactId>
        <version>2.2.4.RELEASE</version>
    </dependency>
    <!-- https://mvnrepository.com/artifact/com.nimbusds/nimbus-jose-jwt -->
    <dependency>
        <groupId>com.nimbusds</groupId>
        <artifactId>nimbus-jose-jwt</artifactId>
        <version>9.8.1</version>
    </dependency>
    <!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-data-redis -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-redis</artifactId>
        <version>2.4.4</version>
    </dependency>
</dependencies>

在application.yml中添加相关配置

主要是Nacos和Redis相关配置:

server:
  port: 9401
spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql:///dgut?serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8&useSSL=true
    username: root
    password: root
  application:
    name: service-oauth2-auth
  cloud:
    nacos:
      discovery:
        server-addr: localhost:8848
  jackson:
    date-format: yyyy-MM-dd HH:mm:ss
  redis:
    database: 0
    port: 6379
    host: localhost
#    password:

使用keytool生成RSA证书

使用keytool生成RSA证书jwt.jks,复制到resource目录下:

keytool -genkey -alias jwt -keyalg RSA -keystore jwt.jks

创建主类

开启服务发现,将认证服务注册到nacos中心:

package com.oauth2;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

@SpringBootApplication
@EnableDiscoveryClient
public class AuthApplication {
public static void main(String[] args) {
        SpringApplication.run(AuthApplication.class);
    }
}

创建UserDTO

数据传输对象(DTO)(Data Transfer Object),是一种设计模式之间传输数据的软件应用系统。数据传输目标往往是数据访问对象从数据库中检索数据。数据传输对象与数据交互对象或数据访问对象之间的差异是一个以不具有任何行为除了存储和检索的数据(访问和存取器)。

添加pom依赖:

<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <version>1.18.20</version>
    <scope>provided</scope>
</dependency>

创建UserDTO类:

package com.oauth2.domain.dto;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.EqualsAndHashCode;

import java.util.List;


@Data
@EqualsAndHashCode(callSuper = false)
@AllArgsConstructor
public class UserDTO {
private Long id;
    private String username;
    private String password;
    private Integer status;
    private List<String> roles;

}

加载用户信息

创建UserServiceImpl类实现Spring Security的UserDetailsService接口,用于加载用户信息。

添加pom依赖:

<dependency>
    <groupId>cn.hutool</groupId>
    <artifactId>hutool-all</artifactId>
    <version>5.6.2</version>
</dependency>

Hutool是一个小而全的Java工具类库,通过静态方法封装,降低相关API的学习成本,提高工作效率,使Java拥有函数式语言般的优雅。

注入PasswordEncoder类:

@Bean
public PasswordEncoder passwordEncoder(){
    return new BCryptPasswordEncoder();
}

创建 SecurityUser类实现UserDetails类:

package com.oauth2.domain;

import com.commons.admin.entity.Admin;
import com.commons.enterprise.entity.EnterpriseAdmin;
import com.commons.student.entity.Student;
import com.oauth2.domain.dto.UserDTO;
import lombok.Data;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.crypto.password.PasswordEncoder;

import java.util.ArrayList;
import java.util.Collection;

/**
 * 实现UserDetails类,获取用户详细信息
 */
@Data
public class SecurityUser implements UserDetails {

    /**
     * ID
     */
    private Long id;
    /**
     * 用户名
     */
    private String username;
    /**
     * 用户密码
     */
    private String password;
    /**
     * 用户状态
     */
    private Boolean enabled;
    /**
     * 权限数据
     */
    private Collection<SimpleGrantedAuthority> authorities;

    public SecurityUser() {

    }

    public SecurityUser(UserDTO userDTO) {
        this.setId(userDTO.getId());
        this.setUsername(userDTO.getUsername());
        this.setPassword(userDTO.getPassword());
        this.setEnabled(userDTO.getStatus() == 1);
        if (userDTO.getRoles() != null) {
            authorities = new ArrayList<>();
            userDTO.getRoles().forEach(item -> authorities.add(new SimpleGrantedAuthority(item)));
        }
    }

    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        return this.authorities;
    }

    @Override
    public String getPassword() {
        return this.password;
    }

    @Override
    public String getUsername() {
        return this.username;
    }

    /**
     * isAccountNonExpired():当前账号是否已经过期
     *
     * isAccountNonLocked():当前账号是否被锁
     *
     * isCredentialsNonExpired():当前账号证书(密码)是否过期
     *
     * isEnabled():当前账号是否被禁用
     *
     * 都要给设成true 否则登录会报出来
     */

    @Override
    public boolean isAccountNonExpired() {
        return true;
    }

    @Override
    public boolean isAccountNonLocked() {
        return true;
    }

    @Override
    public boolean isCredentialsNonExpired() {
        return true;
    }

    @Override
    public boolean isEnabled() {
        return this.enabled;
    }

}

该类通过重写UserDetails接口方法来设定鉴权用户信息。

创建常量类:

package com.oauth2.constant;

public class MessageConstant {
public static final String LOGIN_SUCCESS = "登录成功!";

    public static final String USERNAME_PASSWORD_ERROR = "用户名或密码错误!";

    public static final String CREDENTIALS_EXPIRED = "该账户的登录凭证已过期,请重新登录!";

    public static final String ACCOUNT_DISABLED = "该账户已被禁用,请联系管理员!";

    public static final String ACCOUNT_LOCKED = "该账号已被锁定,请联系管理员!";

    public static final String ACCOUNT_EXPIRED = "该账号已过期,请联系管理员!";

    public static final String PERMISSION_DENIED = "没有访问权限,请联系管理员!";
}

该类定义用户登录各种情况信息,用于封装各种异常信息。

创建UserServiceImpl类实现Spring Security的UserDetailsService接口:

package com.oauth2.service.impl;

import cn.hutool.core.collection.CollUtil;
import com.oauth2.constant.MessageConstant;
import com.oauth2.domain.SecurityUser;
import com.oauth2.domain.dto.UserDTO;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.authentication.AccountExpiredException;
import org.springframework.security.authentication.CredentialsExpiredException;
import org.springframework.security.authentication.DisabledException;
import org.springframework.security.authentication.LockedException;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.stereotype.Service;

import javax.annotation.PostConstruct;
import java.util.ArrayList;
import java.util.List;
import java.util.stream.Collectors;

@Service
public class UserServiceImpl implements UserDetailsService {

private List<UserDTO> userList;

    @Autowired
    private PasswordEncoder passwordEncoder;

    @PostConstruct
    // 该注解被用来修饰一个非静态的void()方法。
    // 被@PostConstruct修饰的方法会在服务器加载Servlet的时候运行,并且只会被服务器执行一次。
    // PostConstruct在构造函数之后执行,init()方法之前执行。
    public void initData() {
        String password = passwordEncoder.encode("123456");
        userList = new ArrayList<>();
        userList.add(new UserDTO(1L, "macro", password, 1, CollUtil.toList("ADMIN")));
        userList.add(new UserDTO(2L, "andy", password, 1, CollUtil.toList("TEST")));
    }

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        List<UserDTO> findUserList = userList.stream().filter(item -> item.getUsername().equals(username)).collect(Collectors.toList());
        if (CollUtil.isEmpty(findUserList)) {
            throw new UsernameNotFoundException(MessageConstant.USERNAME_PASSWORD_ERROR);
        }
        SecurityUser securityUser = new SecurityUser(findUserList.get(0));
        if (!securityUser.isEnabled()) {
            throw new DisabledException(MessageConstant.ACCOUNT_DISABLED);
        } else if (!securityUser.isAccountNonLocked()) {
            throw new LockedException(MessageConstant.ACCOUNT_LOCKED);
        } else if (!securityUser.isAccountNonExpired()) {
            throw new AccountExpiredException(MessageConstant.ACCOUNT_EXPIRED);
        } else if (!securityUser.isCredentialsNonExpired()) {
            throw new CredentialsExpiredException(MessageConstant.CREDENTIALS_EXPIRED);
        }
        return securityUser;
    }

}

该初始化生成一个管理员用户和一个测试用户,通过加载方法返回一个鉴权的用户对象,如果用户登录异常,就报各种情况的异常错误。

添加认证服务相关配置Oauth2ServerConfig

需要配置加载用户信息的服务UserServiceImpl及RSA的钥匙对KeyPair。

实现TokenEnhancer接口:

package com.oauth2.component;

import com.oauth2.domain.SecurityUser;
import org.springframework.security.oauth2.common.DefaultOAuth2AccessToken;
import org.springframework.security.oauth2.common.OAuth2AccessToken;
import org.springframework.security.oauth2.provider.OAuth2Authentication;
import org.springframework.security.oauth2.provider.token.TokenEnhancer;
import org.springframework.stereotype.Component;

import java.util.HashMap;
import java.util.Map;

@Component
public class JwtTokenEnhancer implements TokenEnhancer {
@Override
    public OAuth2AccessToken enhance(OAuth2AccessToken accessToken, OAuth2Authentication authentication) {
        SecurityUser securityUser = (SecurityUser) authentication.getPrincipal();
        Map<String, Object> info = new HashMap<>();
        //把用户ID设置到JWT中
        info.put("id", securityUser.getId());
        ((DefaultOAuth2AccessToken) accessToken).setAdditionalInformation(info);
        return accessToken;
    }
}

该类用于往JWT中添加自定义信息,比如说登录用户的ID。

创建Oauth2ServerConfig:

package com.oauth2.config;

import com.oauth2.component.JwtTokenEnhancer;
import com.oauth2.service.impl.UserServiceImpl;
import lombok.AllArgsConstructor;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.ClassPathResource;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.oauth2.config.annotation.configurers.ClientDetailsServiceConfigurer;
import org.springframework.security.oauth2.config.annotation.web.configuration.AuthorizationServerConfigurerAdapter;
import org.springframework.security.oauth2.config.annotation.web.configuration.EnableAuthorizationServer;
import org.springframework.security.oauth2.config.annotation.web.configurers.AuthorizationServerEndpointsConfigurer;
import org.springframework.security.oauth2.config.annotation.web.configurers.AuthorizationServerSecurityConfigurer;
import org.springframework.security.oauth2.provider.token.TokenEnhancer;
import org.springframework.security.oauth2.provider.token.TokenEnhancerChain;
import org.springframework.security.oauth2.provider.token.store.JwtAccessTokenConverter;
import org.springframework.security.oauth2.provider.token.store.KeyStoreKeyFactory;

import java.security.KeyPair;
import java.util.ArrayList;
import java.util.List;

@AllArgsConstructor
@Configuration
@EnableAuthorizationServer
public class Oauth2ServerConfig extends AuthorizationServerConfigurerAdapter {

private final PasswordEncoder passwordEncoder;
    private final UserServiceImpl userDetailsService;
    private final AuthenticationManager authenticationManager;
    private final JwtTokenEnhancer jwtTokenEnhancer;

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory()
                .withClient("client-app")
                .secret(passwordEncoder.encode("123456"))
                .scopes("all")
                .authorizedGrantTypes("password", "refresh_token")
                .accessTokenValiditySeconds(3600)
                .refreshTokenValiditySeconds(86400);
    }

@Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        TokenEnhancerChain enhancerChain = new TokenEnhancerChain();
        List<TokenEnhancer> delegates = new ArrayList<>();
        delegates.add(jwtTokenEnhancer);
        delegates.add(accessTokenConverter());
        enhancerChain.setTokenEnhancers(delegates); //配置JWT的内容增强器
        endpoints.authenticationManager(authenticationManager)
                .userDetailsService(userDetailsService) //配置加载用户信息的服务
                .accessTokenConverter(accessTokenConverter())
                .tokenEnhancer(enhancerChain);
    }

@Override
    public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
        security.allowFormAuthenticationForClients();
    }

@Bean
    public JwtAccessTokenConverter accessTokenConverter() {
        JwtAccessTokenConverter jwtAccessTokenConverter = new JwtAccessTokenConverter();
        jwtAccessTokenConverter.setKeyPair(keyPair());
        return jwtAccessTokenConverter;
    }

@Bean
    public KeyPair keyPair() {
        // 从classpath下的证书中获取秘钥对
        KeyStoreKeyFactory keyStoreKeyFactory = new KeyStoreKeyFactory(new ClassPathResource("jwt.jks"), "123456".toCharArray());
        return keyStoreKeyFactory.getKeyPair("jwt", "123456".toCharArray());
    }

}

该类是鉴权服务器配置,用于创建一个jwt的鉴权服务端,加载jwt.jks密钥文件,分发token。

通过KeyPairController把公钥暴露出来

由于我们的网关服务需要RSA的公钥来验证签名是否合法,所以认证服务需要有个接口把公钥暴露出来。

package com.oauth2.controller;

import com.nimbusds.jose.jwk.JWKSet;
import com.nimbusds.jose.jwk.RSAKey;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

import java.security.KeyPair;
import java.security.interfaces.RSAPublicKey;
import java.util.Map;

@RestController
public class KeyPairController {

    @Autowired
    private KeyPair keyPair;

    @GetMapping("/rsa/publicKey")
    public Map<String, Object> getKey() {
        RSAPublicKey publicKey = (RSAPublicKey) keyPair.getPublic();
        RSAKey key = new RSAKey.Builder(publicKey).build();
        return new JWKSet(key).toJSONObject();
    }

}

配置Spring Security,允许获取公钥接口的访问

package com.oauth2.config;

import org.springframework.boot.actuate.autoconfigure.security.servlet.EndpointRequest;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .requestMatchers(EndpointRequest.toAnyEndpoint()).permitAll()
                .antMatchers("/rsa/publicKey").permitAll()
                .anyRequest().authenticated();
    }

    @Bean
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

}

创建一个资源服务ResourceServiceImpl

初始化的时候把资源与角色匹配关系缓存到Redis中,方便网关服务进行鉴权的时候获取。

创建Redis常量类:

package com.oauth2.constant;

public class RedisConstant {
    public static final String RESOURCE_ROLES_MAP = "AUTH:RESOURCE_ROLES_MAP";
}

创建ResourceServiceImpl:

package com.oauth2.service.impl;

import cn.hutool.core.collection.CollUtil;
import com.oauth2.constant.RedisConstant;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.stereotype.Service;

import javax.annotation.PostConstruct;
import javax.annotation.Resource;
import java.util.List;
import java.util.Map;
import java.util.TreeMap;

@Service
public class ResourceServiceImpl {

private Map<String, List<String>> resourceRolesMap;

    @Resource
    private RedisTemplate<String,Object> redisTemplate;

    @PostConstruct
    public void initData() {
        resourceRolesMap = new TreeMap<>();
        resourceRolesMap.put("/api/hello", CollUtil.toList("ADMIN"));
        resourceRolesMap.put("/api/user/currentUser", CollUtil.toList("ADMIN", "TEST"));
        redisTemplate.opsForHash().putAll(RedisConstant.RESOURCE_ROLES_MAP, resourceRolesMap);
    }
}

将资源与对应访问权限放到redis缓存。

AuthController自定义Oauth2获取令牌接口

封装API的错误码:

package com.oauth2.api;

public interface IErrorCode {
    long getCode();

    String getMessage();
}

枚举一些常用API操作码:

package com.oauth2.api;

public enum ResultCode implements IErrorCode {
    SUCCESS(200, "操作成功"),
    FAILED(500, "操作失败"),
    VALIDATE_FAILED(404, "参数检验失败"),
    UNAUTHORIZED(401, "暂未登录或token已经过期"),
    FORBIDDEN(403, "没有相关权限");
    private long code;
    private String message;

    private ResultCode(long code, String message) {
        this.code = code;
        this.message = message;
    }

    @Override
    public long getCode() {
        return code;
    }

    @Override
    public String getMessage() {
        return message;
    }
}

CommonResult通用返回对象:

package com.oauth2.api;

public class CommonResult<T> {
private long code;
    private String message;
    private T data;

    protected CommonResult() {
    }

    protected CommonResult(long code, String message, T data) {
        this.code = code;
        this.message = message;
        this.data = data;
    }

    /**
     * 成功返回结果
     *
     * @param data 获取的数据
     */
    public static <T> CommonResult<T> success(T data) {
        return new CommonResult<T>(ResultCode.SUCCESS.getCode(), ResultCode.SUCCESS.getMessage(), data);
    }

    /**
     * 成功返回结果
     *
     * @param data 获取的数据
     * @param  message 提示信息
     */
    public static <T> CommonResult<T> success(T data, String message) {
        return new CommonResult<T>(ResultCode.SUCCESS.getCode(), message, data);
    }

    /**
     * 失败返回结果
     * @param errorCode 错误码
     */
    public static <T> CommonResult<T> failed(IErrorCode errorCode) {
        return new CommonResult<T>(errorCode.getCode(), errorCode.getMessage(), null);
    }

    /**
     * 失败返回结果
     * @param errorCode 错误码
     * @param message 错误信息
     */
    public static <T> CommonResult<T> failed(IErrorCode errorCode,String message) {
        return new CommonResult<T>(errorCode.getCode(), message, null);
    }

    /**
     * 失败返回结果
     * @param message 提示信息
     */
    public static <T> CommonResult<T> failed(String message) {
        return new CommonResult<T>(ResultCode.FAILED.getCode(), message, null);
    }

    /**
     * 失败返回结果
     */
    public static <T> CommonResult<T> failed() {
        return failed(ResultCode.FAILED);
    }

    /**
     * 参数验证失败返回结果
     */
    public static <T> CommonResult<T> validateFailed() {
        return failed(ResultCode.VALIDATE_FAILED);
    }

    /**
     * 参数验证失败返回结果
     * @param message 提示信息
     */
    public static <T> CommonResult<T> validateFailed(String message) {
        return new CommonResult<T>(ResultCode.VALIDATE_FAILED.getCode(), message, null);
    }

    /**
     * 未登录返回结果
     */
    public static <T> CommonResult<T> unauthorized(T data) {
        return new CommonResult<T>(ResultCode.UNAUTHORIZED.getCode(), ResultCode.UNAUTHORIZED.getMessage(), data);
    }

    /**
     * 未授权返回结果
     */
    public static <T> CommonResult<T> forbidden(T data) {
        return new CommonResult<T>(ResultCode.FORBIDDEN.getCode(), ResultCode.FORBIDDEN.getMessage(), data);
    }

    public long getCode() {
        return code;
    }

    public void setCode(long code) {
        this.code = code;
    }

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }

    public T getData() {
        return data;
    }

    public void setData(T data) {
        this.data = data;
    }
}

Oauth2获取Token返回信息封装:

package com.oauth2.domain.dto;

import lombok.Builder;
import lombok.Data;
import lombok.EqualsAndHashCode;

@Data
@EqualsAndHashCode(callSuper = false)
@Builder
public class Oauth2TokenDto {
    /**
     * 访问令牌
     */
    private String token;
    /**
     * 刷新令牌
     */
    private String refreshToken;
    /**
     * 访问令牌头前缀
     */
    private String tokenHead;
    /**
     * 有效时间(秒)
     */
    private int expiresIn;
}

自定义Oauth2获取令牌接口:

package com.oauth2.controller;


import com.oauth2.api.CommonResult;
import com.oauth2.domain.dto.Oauth2TokenDto;
