SpringBoot配置swagger2过程和详解

pom文件

首先pom文件中引入依赖

        <!--swagger2 依赖-->
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
        </dependency>
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
        </dependency>

配置文件

enable作为swagger开关放在配置文件中，可以通过更改配置文件来控制Swagger-ui的显示和隐藏

#swagger开关
swagger2.enable=true

SwaggerConfig

config包下创建SwaggerConfig类

@Configuration
@EnableSwagger2
public class SwaggerConfig {
    //读取配置文件中的enable，true为显示，false为隐藏
    @Value("${swagger2.enable}")
    private boolean enable;

    @Bean
    public Docket createDocke(){
        return new Docket(DocumentationType.SWAGGER_2)
                //进入swagger-ui的信息
                .apiInfo(apiInfo())
                .select()
                //暴露所有controller类的所在的包路径
                .apis(RequestHandlerSelectors.basePackage("com.liang.web.controller"))
                .paths(PathSelectors.any())
                .build()
                .enable(enable);
    }
    //进入swagger-ui的信息
    private ApiInfo apiInfo(){
        return new ApiInfoBuilder()
                //该项目的名字
                .title("Spring Boot 2.x教程")
                //该项目的描述
                .description("spring boot2.x 描述")
                .version("1.0")
                .build();
    }
}

此时运行项目便可以进入到Swagger页面

在网页中输入"本机地址:端口号/swagger-ui.html"

 

经常用的Swagger注解

实体Model中注解

@Data
//实体路径和描述
@ApiModel(value = "com.liang.web.Model.UpdateUserModel",description = "接收更新用户数据")
public class UpdateUserModel {
    //字段描述
    @ApiModelProperty(value = "用户id")
    private String id;
    @ApiModelProperty(value = "账号")
    private String username;
    @ApiModelProperty(value = "密码")
    private String password;
    @ApiModelProperty(value = "性别")
    private String sex;
    @ApiModelProperty(value = "手机号")
    private String phone;
    @ApiModelProperty(value = "地区")
    private String createWhere;
    @ApiModelProperty(value = "邮件")
    private String email;
    @ApiModelProperty(value = "暱称")
    private String nickName;
}

controller层注解

@RestController()
@RequestMapping("/api")
//接口模块描述信息
@Api(tags = "用户模块",description = "用户相关模块接口")
public class UserController {
    @Autowired
    private UserService userService;

    @GetMapping("/getUser")
    //接口描述信息
    @ApiOperation(value = "获取用户详情")
    @ApiImplicitParams({
            //给Swagger-UI中的输入框中设置默认值
            @ApiImplicitParam(name = "id",value = "用户id",defaultValue = "123456")
    })
    public SysUser getUserDetail(@ApiParam(value = "用户id",required = true) @RequestParam String id) {
        return userService.getUserInfo(id);
    }

    @PutMapping("/user")
    //接口描述信息
    @ApiOperation(value = "获取用户详情")
    public String updateUserInfo(@RequestBody UpdateUserModel userModel) {
        return userService.updateUserInfo(userModel);
    } 
}
