【SpringBoot】Java MVC 集成 Swagger 生成 API 文档

使用Swagger你只需要按照它的规范去定义接口及接口相关的信息,就可以做到生成接口文档,以及在线接口调试页面。官网: https://swagger.io/

Knife4j 是为Java MVC框架集成Swagger生成Api文档的增强解决方案。

}

在这里插入图片描述

@RestController
@RequestMapping("/admin/employee")
@Slf4j
@Api(tags = "员工相关接口")
public class EmployeeController {@Autowiredprivate EmployeeService employeeService;@Autowiredprivate JwtProperties jwtProperties;/*** 登录** @param employeeLoginDTO* @return*/@PostMapping("/login")@ApiOperation(value = "员工登录")public Result<EmployeeLoginVO> login(@RequestBody EmployeeLoginDTO employeeLoginDTO) {log.info("员工登录：{}", employeeLoginDTO);Employee employee = employeeService.login(employeeLoginDTO);//登录成功后，生成jwt令牌Map<String, Object> claims = new HashMap<>();claims.put(JwtClaimsConstant.EMP_ID, employee.getId());String token = JwtUtil.createJWT(jwtProperties.getAdminSecretKey(),jwtProperties.getAdminTtl(),claims);EmployeeLoginVO employeeLoginVO = EmployeeLoginVO.builder().id(employee.getId()).userName(employee.getUsername()).name(employee.getName()).token(token).build();return Result.success(employeeLoginVO);}/*** 退出** @return*/@PostMapping("/logout")@ApiOperation(value = "员工退出")public Result<String> logout() {return Result.success();}/*** 新增员工* @param employeeDTO* @return*/@PostMapping@ApiOperation("新增员工")public Result save(@RequestBody EmployeeDTO employeeDTO) {log.info("新增员工：{}", employeeDTO);employeeService.save(employeeDTO);return Result.success();}
}

@Data
@ApiModel(description = "员工登录时传递的数据模型")
public class EmployeeLoginDTO implements Serializable {@ApiModelProperty("用户名")private String username;@ApiModelProperty("密码")private String password;}
