Shiro之与SpringMVC集成
作者：互联网
SpringMVC 环境省略
http://shiro.apache.org/download.html
pom.xml增加maven依赖

web.xml增加shiro-filter,放在所有filter之前
<!-- Shiro Filter -->
<filter>
<filter-name>shiroFilter</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
<init-param>
<param-name>targetFilterLifecycle</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>shiroFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
建立首页，登录页等等相关控制器和页面
增加spring-shiro.xml配置文件
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

<!-- 未认证,要跳转的url，非必须的属性，默认会自动寻找Web工程根目录下的"/login.jsp"页面 -->
<property name="loginUrl" value="/loginPage"></property>
<!-- 未授权,要跳转的url -->
<property name="unauthorizedUrl" value="/unauthorizedPage"></property>
<property name="filterChainDefinitions">

<bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">

在web.xml里的contextConfigLocation的Spring核心监听器增加spring-shiro.xml文件路径
控制器核心代码如下
package com.zns.controller;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.DisabledAccountException;
import org.apache.shiro.authc.ExcessiveAttemptsException;
import org.apache.shiro.authc.ExpiredCredentialsException;
import org.apache.shiro.authc.IncorrectCredentialsException;
import org.apache.shiro.authc.LockedAccountException;
import org.apache.shiro.authc.UnknownAccountException;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.authz.UnauthorizedException;
import org.apache.shiro.subject.Subject;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class AccountController {
@RequestMapping("/loginPage")
public String loginPage(){
return "/login";
}
@RequestMapping(value = "/doLogin")
public String doLogin(HttpServletRequest request, Model model) {
String msg = "";
String username = request.getParameter("username");
String password = request.getParameter("password");
System.out.println("用户名: "+username+" 密码: "+password);
UsernamePasswordToken token = new UsernamePasswordToken(username, password);
token.setRememberMe(true);
Subject subject = SecurityUtils.getSubject();
try {
subject.login(token);
if (subject.isAuthenticated()) {
return "redirect:/";
} else {
return "/login";
}
} catch (IncorrectCredentialsException e) {
msg = "登录密码错误. Password for account " + token.getPrincipal() + " was incorrect.";
model.addAttribute("message", msg);
System.out.println(msg);
} catch (ExcessiveAttemptsException e) {
msg = "登录失败次数过多";
model.addAttribute("message", msg);
System.out.println(msg);
} catch (LockedAccountException e) {
msg = "帐号已被锁定. The account for username " + token.getPrincipal() + " was locked.";
model.addAttribute("message", msg);
System.out.println(msg);
} catch (DisabledAccountException e) {
msg = "帐号已被禁用. The account for username " + token.getPrincipal() + " was disabled.";
model.addAttribute("message", msg);
System.out.println(msg);
} catch (ExpiredCredentialsException e) {
msg = "帐号已过期. the account for username " + token.getPrincipal() + " was expired.";
model.addAttribute("message", msg);
System.out.println(msg);
} catch (UnknownAccountException e) {
msg = "帐号不存在. There is no user with username of " + token.getPrincipal();
model.addAttribute("message", msg);
System.out.println(msg);
} catch (UnauthorizedException e) {
msg = "您没有得到相应的授权！" + e.getMessage();
model.addAttribute("message", msg);
System.out.println(msg);
}
return "/login";
}
@RequestMapping("/doLogout")
public void doLogout(HttpServletRequest request,HttpServletResponse response) throws Exception{
Subject subject = SecurityUtils.getSubject();
if (subject != null) {
try{
subject.logout();
}catch(Exception ex){
}
}
response.sendRedirect("loginPage");
}
}
login.jsp

新增一个Realm1继承AuthorizingRealm类
package com.zns.realm;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authc.LockedAccountException;
import org.apache.shiro.authc.SimpleAuthenticationInfo;
import org.apache.shiro.authc.UnknownAccountException;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.crypto.hash.SimpleHash;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
public class Realm1 extends AuthorizingRealm {
/**
* 认证
*/
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
//把AuthenticationToken转换成UsernamePasswordToken
UsernamePasswordToken usernamePasswordToken=(UsernamePasswordToken)authenticationToken;
//获取username
String username=usernamePasswordToken.getUsername();
//根据username从数据库查询信息(注入并调用UserService方法),此处省略
//根据获取的用户信息，决定是否抛出AuthenticationException异常，此处写死
if(username.equals("unknown")){
throw new UnknownAccountException("用户不存在!");
}
if (username.equals("lock")) {
throw new LockedAccountException("用户被锁定!");
}
//构建并返回AuthenticationInfo，通常是SimpleAuthenticationInfo
//principal:可以是username,也可以是数据表对应的用户实体类对象
//credentials:从数据库获取的密码
//realmName:当前realm对象的name
Object principal=username;
//Object credentials="123456";
Object credentials=new SimpleHash("MD5", "123456", "", 1);
String realmName=this.getName();
SimpleAuthenticationInfo info=new SimpleAuthenticationInfo(principal, credentials, realmName);
return info;
}
/**
* 授权
*/
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
return null;
}
public static void main(String[] args) {
String algorithmName="MD5";
String source="123456";
String salt="";
int hashIterations=1;
Object result=new SimpleHash(algorithmName, source, salt, hashIterations);
System.out.println(result);
}
}
运行项目测试登录认证功能.......
