【转载】Springboot2.3.5 接收 post json数据，并给使用 swagger 给 dto增加注解

参考

• pringboot之接收json字符串的两种方式-yellowcong
• Swagger2常用注解说明

正文

• 通过@RequestBody 接收json

@ResponseBody
@RequestMapping(value = "/json/data", method = RequestMethod.POST, produces = "application/json;charset=UTF-8")
public String getByJSON(@RequestBody JSONObject jsonParam) {
    // 直接将json信息打印出来
    System.out.println(jsonParam.toJSONString());

    // 将获取的json数据封装一层，然后在给返回
    JSONObject result = new JSONObject();
    result.put("msg", "ok");
    result.put("method", "json");
    result.put("data", jsonParam);

    return result.toJSONString();
}

• 接收json数据，并给api编写参数文档

  1. Dto

     	@ApiModel(value = "登陆请求参数")
     	@Data
     	public class LoginRequestDto
     	{
     		@ApiModelProperty(value = "账号")
     		protected String account;
     		@ApiModelProperty(value = "密码")
     		protected String password;
     	}
     

  2. 控制器调用

     @ApiOperation(value = "默认登陆", notes = "输入账号与密码就可以登陆")
     @PostMapping(value = "def_login", consumes = "application/json", produces = "application/json;charset=UTF-8")
     public ResponseEntity<ResponseBodyUtils<LoginResponseDto>> show(@RequestBody LoginRequestDto loginRequestDto ) throws Exception{
     	//
     	String account = loginRequestDto.getAccount();
     	String password = loginRequestDto.getPassword();
     	//
     	Student student = studentService.findByAccount(account);
     	if(!student.getPassword().equals(DigestUtils.md5DigestAsHex(password.getBytes()))){
     		throw new Exception("账号或者密码错误");
     	}
     	// 学生转dto
     	InfoStudentDto infoStudentDto = modelMapper.map(student, InfoStudentDto.class);
     	//
     	LoginResponseDto loginDto = new LoginResponseDto(JwtUtils.getStudentToken(student), infoStudentDto);
     	return ResponseEntity.ok(new ResponseBodyUtils(loginDto));
     }
