简单介绍一下Swagger：
Swagger是一个规范和完整的框架，用于生成、描述、调用和可视化 RESTful 风格的 Web 服务。总体目标是使客户端和文件系统作为服务器以同样的速度来更新。文件的方法，参数和模型紧密集成到服务器端的代码，允许API来始终保持同步。
IJ怎么配置Swagger呢？
pom.xml

<dependency><groupId>io.springfox</groupId><artifactId>springfox-swagger2</artifactId><version>3.0.0</version></dependency>

在swagger进行config配置

import io.swagger.annotations.ApiOperation;
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.service.ApiKey;
import springfox.documentation.service.SecurityScheme;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;import java.util.ArrayList;
import java.util.List;@Configuration
@EnableSwagger2
public class SwaggerConfig {@Beanpublic Docket createRestApi() {return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo()).select()//加了ApiOperation注解的类，才生成接口文档.apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class))//包下的类，才生成接口文档.paths(PathSelectors.any()).build().securitySchemes(securitySchemes());}private ApiInfo apiInfo() {return new ApiInfoBuilder().title("SWagger").description("swagger文档").termsOfServiceUrl("").version("3.0.0").build();}private List<SecurityScheme> securitySchemes() {List<SecurityScheme> apiKeyList = new ArrayList();apiKeyList.add(new ApiKey("x-auth-token", "x-auth-token", "header"));return apiKeyList;}}

到此就可以运行项目，然后输入本地localhost：端口/doc.html查看对外接口了
