注解使用

@Api

用在请求类上,说明该类的作用。可以标记一个Controller类做为swagger文档资源。

value:url的路径值,在UI界面上也看到,可以不用配置。

String value() default "";

tags:说明该类的作用,可以在UI界面上看到的内容

String[] tags() default {""};

produces:配置返回数据类型,例如application/json,application/xml等

String produces() default "";

consumes:配置请求头,例如application/json,application/xml等

String protocols() default "";

authorizations:高级特性认证时配置

Authorization[] authorizations() default {@Authorization("")};

hidden:默认为false,配置为true将在文档中隐藏

boolean hidden() default false;

@ApiOperation

用在请求的方法上,说明方法的用途、作用

value:说明方法的用途、作用

String value();

notes:方法的备注说明

String notes() default "";

tags:

String[] tags() default {""};

response:返回的对象

Class<?> response() default Void.class;

responseContainer:这些对象是有效的List,Set,Map,其他是无效的

String responseContainer() default "";

responseReference:

String responseReference() default "";

httpMethod:可以配置其中HTTP请求方式

String httpMethod() default "";

nickname:

String nickname() default "";

ResponseHeader[] responseHeaders() default {@ResponseHeader(
name = "",
response = Void.class
)};

code:HTTP的状态码,默认200

int code() default 200;

extensions:扩展属性

Extension[] extensions() default {@Extension(
properties = {@ExtensionProperty(
name = "",
value = ""
)}
)};

@ApiImplicitParams

用在请求的方法上,表示一组参数说明,里面通过ApiImplicitParam配置具体参数。

public @interface ApiImplicitParams {
ApiImplicitParam[] value();
}

@ApiImplicitParam

用在请求的方法上,表示单个参数说明;或者用在@ApiImplicitParams注解中,指定一个请求参数的各个方面

name:参数名

String name() default "";

value:参数说明解释

String value() default "";

defaultValue:参数的默认值

String defaultValue() default "";

allowableValues:

String allowableValues() default "";

required:参数是否必传 true | false,默认false

boolean required() default false;

access:

String access() default "";

allowMultiple:

boolean allowMultiple() default false;

dataType:参数类型,默认String,只作为标志说明,不做实际验证,String和Long

String dataType() default "";

dataTypeClass:

Class<?> dataTypeClass() default Void.class;

paramType:查询参数位置

  header:请求参数放置于 Header,使用@RequestHeader获取

  query:请求参数放置于请求地址后边,使用@RequestParam获取

  path:请求参数放置于请求地址路径中,使用@PathVariable获取

  body:以流的形式提交参数,仅支持POST

  form:以form表单的形式提交参数,仅支持POST

String paramType() default "";

example:

String example() default "";

examples:

Example examples() default @Example({@ExampleProperty(
mediaType = "",
value = ""
)});

type:

String type() default "";

format:

String format() default "";

allowEmptyValue:

boolean allowEmptyValue() default false;

readOnly:

boolean readOnly() default false;

collectionFormat:

String collectionFormat() default "";

@ApiParam

public @interface ApiParam {
String name() default ""; String value() default ""; String defaultValue() default ""; String allowableValues() default ""; boolean required() default false; String access() default ""; boolean allowMultiple() default false; boolean hidden() default false; String example() default ""; Example examples() default @Example({@ExampleProperty(
  mediaType = "",
  value = ""
   )}); String type() default ""; String format() default ""; boolean allowEmptyValue() default false; boolean readOnly() default false; String collectionFormat() default "";
}

@ApiModel

一般用在请求参数无法使用@ApiImplicitParam注解进行描述的时候,用于对类进行说明,描述一个Model的信息,表示参数用实体类接收。

public @interface ApiModel {
String value() default ""; String description() default ""; Class<?> parent() default Void.class; String discriminator() default ""; Class<?>[] subTypes() default {}; String reference() default "";
}

@ApiModelProperty

注解用于方法、字段,表示对model属性的说明或者数据操作更改,配合ApiModel一起使用。

public @interface ApiModelProperty {
String value() default ""; String name() default ""; String allowableValues() default ""; String access() default ""; String notes() default ""; String dataType() default ""; boolean required() default false; int position() default 0; boolean hidden() default false; String example() default ""; boolean readOnly() default false; String reference() default ""; boolean allowEmptyValue() default false;
}

@ApiResponses

用在请求的方法上,表示一组响应

public @interface ApiResponses {
ApiResponse[] value();
}

@ApiResponse

用在@ApiResponses中,一般用于表达一个错误的响应信息

public @interface ApiResponse {
int code(); String message(); Class<?> response() default Void.class; String reference() default ""; ResponseHeader[] responseHeaders() default {@ResponseHeader(
  name = "",
  response = Void.class
  )}; String responseContainer() default "";
}

@ApiIgnore

用在Controller类或者接口方法上,表示该类或者接口被忽略,不在接口文档显示

public @interface ApiIgnore {
//简要说明为何忽略此参数/操作
String value() default "";
}

问题

目前了解到的是Swagger不支持直接获取JSONObject和Map类型的参数,这种参数内部字段不可知,文档显示不出来

如果不想封装为一个Model的话可以参考下面的博客实现下,自定义一个注解。
