一、maven导入Swagger　　

 在pom.xml中引入Swagger依赖

        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.9.2</version>
        </dependency>
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.9.2</version>
        </dependency>

二、创建SwaggerConfig配置类

package com.example.demo.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;

@Configuration
@EnableSwagger2
public class SwaggerConfig {

    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.example.demo.controller"))
                .paths(PathSelectors.any()) // 可以根据url路径设置哪些请求加入文档，忽略哪些请求
                .build()
                .apiInfo(apiInfo());
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("接口文档API") //设置文档的标题
                .description("Service API 接口文档") // 设置文档的描述
                .version("1.0") // 设置文档的版本信息-> 1.0.0 Version information
                .termsOfServiceUrl("http://www.baidu.com") // 设置文档的License信息->1.3 License information
                .build();
    }
}

三、Swagger文档说明

 四、接口请求

接口默认端口为8080，请求地址为:http://localhost:8080/swagger-ui.html
