swagger常用注解说明

@Api

用在请求的类上
@Api(tags = “该类的作用进行说明”)

@ApiOperation

@ApiOperation(value=“改方法的作用”,note=“备注”)

@ApiImplicitParams

@ApiImplicitParams:用在请求的方法上,表示一组参数说明
@ApiImplicitParam:用在@ApiImplicitParams注解中,指定一个请求参数的各个方面
name:参数名
value:参数的汉字说明、解释
required:参数是否必须传
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
dataType:参数类型,默认String,其它值dataType=“Integer”
defaultValue:参数的默认值
多个 @ApiImplicitParam 注解需要放在一个 @ApiImplicitParams 注解中
@ApiImplicitParam 注解中虽然可以指定参数是必填的,但是却不能代替 @RequestParam(required = true) ,
前者的必填只是在 Swagger 框架内必填,抛弃了 Swagger ,这个限制就没用了,所以假如开发者需要指定一个参数必填, @RequestParam(required = true) 注解还是不能省略。

@ApiModel

如果参数是一个对象(例如上文的更新接口),对于参数的描述也可以放在实体类中。例如下面一段代码
@ApiModelProperty:用在属性上,描述类的属性

@ApiModel(value = "用户对象",description = "用户表")
public class User {
    @Id
    @ApiModelProperty(value = "id",required = true)
    private int userId;
    @ApiModelProperty(value = "用户名称",required = true)
    private String userName;
}
