spring mvc 注解整理(一)

@Controller和@RestController: RestController = @ResponseBody + @Controller  所有返回都是json类型,无法跳转到jsp页面,但是不用在每个方法前加@ReaponseBody

 

 @ApiOperation 说明:
　　value:函数说明

　　notes:函数用途

　　response:返回值类型

@RequestMapping(value = "/v1/apis", method = RequestMethod.POST)
  value:访问路径
  method:请求方式

@Validated:配合pojo类中的注解使用@NotBlank,用与校验属性的空值,后面必须加 BindingResult bindingResult

Insert.class:表示插入时校验

@RequestBody 将json 转成对象

@ApiParam(value = "Created api object", required = true)
 value:参数说明
required:参数是否能为空 

 @ApiOperation(value = "创建api", notes = "根据ApisRequestVo请求对象创建api", response = RequestResult.class)
  @RequestMapping(value = "/v1/apis", method = RequestMethod.POST)
  @ResponseBody
  public ModelAndView createApi(
      @Validated({Insert.class}) @RequestBody @ApiParam(value = "Created api object",
          required = true) ApisRequestVo vo,
      BindingResult bindingResult) {
    LOGGER.debug("create api ");
    RequestResult result = null;
    /*
     * Map<String, List<String>> errorMsg = parseErrorMsg(bindingResult);
     * 
     * if (errorMsg != null) { result = new RequestResult(); result.setErrorMsg(errorMsg); return
     * createModelAndView(result); }
     */
    vo.setId(StringUtils.EMPTY);
    result = new RequestResult(apiService.createApiService(vo));
    return createModelAndView(result);
  }

@PathVariable(value = "id", required = true) String id)
用来接收restful请求方式的参数

@ApiOperation(value = "删除api", notes = "根据id删除 api", response = RequestResult.class)
  @RequestMapping(value = "/v1/apis/{id}", method = RequestMethod.DELETE)
  public ModelAndView deleteApiById(@ApiParam(value = "api Id",
      required = true) @PathVariable(value = "id", required = true) String id) {
    RequestResult result = new RequestResult(apiService.deleteApi(id));
    return createModelAndView(result);
  }

 @NotBlank(message = "apiId不能为空", groups = { Insert.class, Update.class })
校验参数.配合@Validated使用

@ApiModelProperty(required = true, value = "apiId", dataType = "String"

required:是否可以为空
value:属性说明

dataType:属性类型

public class ApisConfig implements Serializable{
    

    private static final long serialVersionUID = 1L;
    
    @NotBlank(message = "apiId不能为空", groups = { Insert.class, Update.class })
    @ApiModelProperty(required = true, value = "apiId", dataType = "String")
    private String apiId;
