springboot 整合Swagger2的使用
Swagger2相较于传统Api文档的优点
手写Api文档的几个痛点:
文档需要更新的时候,需要再次发送一份给前端,也就是文档更新交流不及时。
接口返回结果不明确
不能直接在线测试接口,通常需要使用工具,比如postman
接口文档太多,不好管理
Swagger也就是为了解决这个问题,当然也不能说Swagger就一定是完美的,当然也有缺点,最明显的就是代码移入性比较强。
可以直接使用Swagger editor编写接口文档,我们这里讲解的是SpringBoot整合Swagger2,直接生成接口文档的方式。

@Configuration
public class Swagger2Configuration {
@Bean
public Docket createRestApi() {
return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo())
.select()
.apis(RequestHandlerSelectors.basePackage("com.boss.hr.train.fishkkmybatis.controller"))
.paths(PathSelectors.any())
.build();
}
private ApiInfo apiInfo() {
return new ApiInfoBuilder()
.title("springboot利用swagger构建api文档")
.description("fishkk的Swagger")
.version("1.0")
.build();
}
}
在启动函数出天价@EnableSwagger2,到这里就可以正常的使用Swagger2 了

启动SpringBoot项目,访问 http://localhost:8080/swagger-ui.html
可以看到上诉类似的结果,我的项目启动太麻烦了含SpringCloud 就不展示了。
Swagger2的注解
swagger通过注解表明该接口会生成文档,包括接口名、请求方法、参数、返回信息的等等。
- @Api:修饰整个类,描述Controller的作用
- @ApiOperation:描述一个类的一个方法,或者说一个接口
- @ApiParam:单个参数描述
- @ApiModel:用对象来接收参数
- @ApiProperty:用对象接收参数时,描述对象的一个字段
- @ApiResponse:HTTP响应其中1个描述
- @ApiResponses:HTTP响应整体描述
- @ApiIgnore:使用该注解忽略这个API
- @ApiError :发生错误返回的信息
- @ApiImplicitParam:一个请求参数
- @ApiImplicitParams:多个请求参数
