1.导入依赖

   <!--引入swagger--><dependency><groupId>io.springfox</groupId><artifactId>springfox-swagger2</artifactId><version>2.7.0</version></dependency><dependency><groupId>io.springfox</groupId><artifactId>springfox-swagger-ui</artifactId><version>2.7.0</version></dependency>

2.

• 新建一个 SwaggerConfig 类 写入下面内容

• package com.example.hellowww.config;
  import org.springframework.context.annotation.Bean;
  import org.springframework.context.annotation.Configuration;
  import springfox.documentation.builders.ApiInfoBuilder;
  import springfox.documentation.builders.PathSelectors;
  import springfox.documentation.builders.RequestHandlerSelectors;
  import springfox.documentation.service.ApiInfo;
  import springfox.documentation.spi.DocumentationType;
  import springfox.documentation.spring.web.plugins.Docket;
  import springfox.documentation.swagger2.annotations.EnableSwagger2;/*** Swagger使用的配置文件*/
  @Configuration
  @EnableSwagger2//启用Swagger2功能
  public class SwaggerConfig {@Beanpublic Docket createRestApi(){return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo()).select().apis(RequestHandlerSelectors.basePackage("com"))//com包下的所以API都交给Swagger管理// .apis(RequestHandlerSelectors.withClassAnnotation(Api.class)).paths(PathSelectors.any()).build();}//API文档页面显示信息private ApiInfo apiInfo(){return new ApiInfoBuilder().title("演示项目API").description("xx相关接口的文档")
  //                .termsOfServiceUrl("http://localhost:8080/hello")
  //                .version("1.0").build();}
  }
