　　controller  上注解：

@Api(value = "/XXX",tags = "查询接口")

method 上注解 示例：

?

12345

@ApiOperation(value = "XXX",notes = "XXXX")    @ApiImplicitParams({            @ApiImplicitParam(name = "methodName",value = "XXX",required = true,dataType = "String",paramType = "query"),            @ApiImplicitParam(name = "params",value = "XXXXX",required = true,paramType = "body")    })

public Result selectServiceRun(String methodName,
                        @RequestBody Map<String, Object> params,
                        HttpServletRequest request) {

　

说明：

• @Api：用在类上，说明该类的作用
• @ApiOperation：用在方法上，说明方法的作用
• @ApiImplicitParams：用在方法上包含一组参数说明
• @ApiImplicitParam：用在@ApiImplicitParams注解中，指定一个请求参数的各个方面
  • paramType：参数放在哪个地方
    • header-->请求参数的获取：@RequestHeader
    • query-->请求参数的获取：@RequestParam
    • path（用于restful接口）-->请求参数的获取：@PathVariable
    • body（不常用）
    • form（不常用）
  • name：参数名
  • dataType：参数类型
  • required：参数是否必须传
  • value：参数的意思
  • defaultValue：参数的默认值
• @ApiResponses：用于表示一组响应
• @ApiResponse：用在@ApiResponses中，一般用于表达一个错误的响应信息
  • code：数字，例如400
  • message：信息，例如"请求参数没填好"
  • response：抛出异常的类
• @ApiModel：描述一个Model的信息（这种一般用在post创建的时候，使用@RequestBody这样的场景，请求参数无法使用@ApiImplicitParam注解进行描述的时候）
  • @ApiModelProperty：描述一个model的属性
