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 "";

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。
