swagger+springboot简单应用

作者:互联网

1.简介:

knife4j 是swagger-ui 的增强,优化了api文档界面; 官网: https://doc.xiaominfo.com/knife4j/documentation/ ;

2.springboot工程添加swagger:

环境准备:

        <!--注入web-->

        <dependency>

            <groupId>org.springframework.boot</groupId>

            <artifactId>spring-boot-starter-web</artifactId>

            <version>2.5.0</version>

        </dependency>

        <!--注入lombok-->

        <dependency>

            <groupId>org.projectlombok</groupId>

            <artifactId>lombok</artifactId>

            <version>1.18.14</version>

        </dependency>

        <dependency>

            <groupId>com.alibaba</groupId>

            <artifactId>fastjson</artifactId>

            <version>1.2.47</version>

        </dependency>

 

依赖引入:

      

            <dependency>

            <groupId>com.github.xiaoymin</groupId>

            <artifactId>knife4j-spring-boot-starter</artifactId>

            <version>3.0.3</version>

            <exclusions>

                <exclusion>

                    <artifactId>swagger-annotations</artifactId>

                    <groupId>io.swagger</groupId>

                </exclusion>

            </exclusions>

        </dependency>

        <dependency>

            <artifactId>swagger-annotations</artifactId>

            <groupId>io.swagger</groupId>

            <version>1.5.22</version>

        </dependency>

 

创建配置类:

package com.example.common;

 

import com.github.xiaoymin.knife4j.spring.annotations.EnableKnife4j;

import org.springframework.beans.factory.annotation.Value;

import org.springframework.context.annotation.Bean;

import org.springframework.context.annotation.Configuration;

import springfox.documentation.builders.ApiInfoBuilder;

import springfox.documentation.builders.PathSelectors;

import springfox.documentation.builders.RequestHandlerSelectors;

import springfox.documentation.spi.DocumentationType;

import springfox.documentation.spring.web.plugins.Docket;

import springfox.documentation.swagger2.annotations.EnableSwagger2;

 

@EnableSwagger2

@EnableKnife4j

@Configuration

public class SwaggerConfig {

    @Value("server.servlet.context-path")

    private String contextPath;

 

    @Value("${spring.profiles.active}")

    private String deployMode;

 

    @Bean(value = "defaultApi2")

    public Docket defaultApi2() {

        Docket docket = new Docket(DocumentationType.SWAGGER_2)

                .apiInfo(new ApiInfoBuilder()

                        //.title("swagger-bootstrap-ui-demo RESTful APIs")

                        .description("# swagger-bootstrap-ui-demo RESTful APIs")

                        .version("1.0")

                        .build())

                .pathMapping(!deployMode.toLowerCase().equals("dev") ? contextPath : "/")

                //分组名称

                .groupName("2.X版本")

                .select()

                //这里指定Controller扫描包路径

                .apis(RequestHandlerSelectors.basePackage("com.example.controller"))

                .paths(PathSelectors.any())

                .build();

        return docket;

    }

}

 

创建实体:

package com.example.vo;

 

import com.fasterxml.jackson.annotation.JsonFormat;

import io.swagger.annotations.ApiModel;

import io.swagger.annotations.ApiModelProperty;

import lombok.Data;

 

import java.time.LocalDateTime;

import java.util.List;

 

@Data

@ApiModel("用户信息实体")

public class UserInfoVo {

    @ApiModelProperty(value = "id标识", example = "1")

    private String id;

 

    @ApiModelProperty(value = "id标识数组", example = "['1','2']")

    private String[] ids;

 

    @ApiModelProperty(value = "姓名", example = "张三")

    private String name;

 

    @ApiModelProperty(value = "年龄", example = "18")

    private Integer age;

 

    @ApiModelProperty(value = "性别(M(男)/F(女))", example = "M")

    private String sex;

 

    @ApiModelProperty(value = "手机号码", example = "15200000000")

    private String phone;

 

    @ApiModelProperty(value = "状态", example = "1")

    private Integer auditStatus;

 

    @ApiModelProperty(value = "状态数组", example = "[1,2]")

    private Integer[] auditStatuss;

 

    @ApiModelProperty(value = "状态集合", example = "[1,2]")

    private List<Integer> auditStatusList;

 

    @ApiModelProperty(value = "创建人")

    private String createdBy = "system";

 

    @ApiModelProperty(value = "创建时间")

    @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss", timezone = "GMT+8")

    private LocalDateTime createdDate;

 

    @ApiModelProperty(value = "更新人")

    private String updatedBy = "system";

 

    @ApiModelProperty(value = "更新时间")

    @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss", timezone = "GMT+8")

    private LocalDateTime updatedDate;

 

}

创建controller:

package com.example.controller;

 

import com.alibaba.fastjson.JSON;

import com.example.vo.UserInfoVo;

import io.swagger.annotations.Api;

import io.swagger.annotations.ApiImplicitParam;

import io.swagger.annotations.ApiImplicitParams;

import io.swagger.annotations.ApiOperation;

import io.swagger.v3.oas.annotations.parameters.RequestBody;

import lombok.extern.slf4j.Slf4j;

import org.apache.commons.lang3.StringUtils;

import org.springframework.validation.annotation.Validated;

import org.springframework.web.bind.annotation.*;

 

@Slf4j

@RestController

@Api(value = "首页模块")

@RequestMapping("/test")

public class TestController {

 

 

    @RequestMapping("/hello")

    public String sayHello() {

        log.info("Hello world!");

        return "Hello world!";

    }

 

    @ApiOperation(value = "获取用户信息")

    @ApiImplicitParams({

            @ApiImplicitParam(name = "name", value = "姓名"),

            @ApiImplicitParam(name = "phone", value = "电话")})

    @GetMapping("/getUser")

    public UserInfoVo getUser(@RequestParam("name") String name, @RequestParam("phone") String phone) {

        log.info("getUser 入参: name:{},phone:{}", name, phone);

        UserInfoVo userInfoVo = new UserInfoVo();

        if (StringUtils.isNotEmpty(name)) {

            userInfoVo.setName(name);

        }

        if (StringUtils.isNotEmpty(phone)) {

            userInfoVo.setPhone(phone);

        }

        return userInfoVo;

    }

 

    @ApiOperation(value = "获取用户信息")

    @PostMapping("/getUserByCondition")

    public UserInfoVo getUserByCondition(@Validated @RequestBody UserInfoVo userInfoVo) {

        log.info("getUserByCondition 入参: {}", JSON.toJSONString(userInfoVo));

        return userInfoVo;

    }

}

 

 

注意: 使用swagger注释对象并使用example时,注意数组集合类型的属性格式是否正确,否则会出现swagger无法解析,界面无法打开;
