在springBoot启动类中配置swagger

package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import springfox.documentation.annotations.ApiIgnore;
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;


@SpringBootApplication
@EnableSwagger2
public class DemoApplication {
	public static void main(String[] args) {
		SpringApplication.run(DemoApplication.class, args);
	}

	@Bean
	public Docket createPcApi() {
		return new Docket(DocumentationType.SWAGGER_2)
				.apiInfo(apiInfo("接口文档")).select()
				.apis(RequestHandlerSelectors.any()).paths(PathSelectors.any())
//				.paths(Predicates.not(PathSelectors.regex("/error.*")))
				.build().groupName("1.所有接口")
				.ignoredParameterTypes(ApiIgnore.class);
	}

	/**
	 * APP接口
	 */
	@Bean
	public Docket createMobileApi() {
		return new Docket(DocumentationType.SWAGGER_2)
				.apiInfo(apiInfo("APP接口文档（移动应用商店android和iOS及部分html5页面接口）")).select()
				.apis(RequestHandlerSelectors.any()).paths(PathSelectors.ant("/api/**"))
				.build().groupName("2.APP接口文档").ignoredParameterTypes(ApiIgnore.class);
	}


	/**
	 * ApiInfo
	 */
	private ApiInfo apiInfo(String title) {
		return new ApiInfoBuilder().title(title).version("1.0").build();
	}
}

启动项目，在地址栏输入访问地址http://localhost:8080/swagger-ui.html 即可以访问接口

代码中注释的那一行是控制图中标（3）的默认错误接口的，可以将其隐藏。

代码中的每一个Bean是控制图中（2）的，可以根据访问层的路径将接口分类
