1、新建SpringBoot-Web项目

2、导入Swagger的maven依赖

        <!-- https://mvnrepository.com/artifact/io.springfox/springfox-swagger2 -->
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>3.0.0</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/io.springfox/springfox-swagger-ui -->
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>3.0.0</version>
        </dependency>

3、编写HelloWorld测试

4、配置SwaggerConfiger,下一个如下的配置文件

package com.gsl.swagger.config;

import org.springframework.context.annotation.Configuration;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@Configuration
@EnableSwagger2
public class SwaggerConfig {
    
}

5、测试运行，访问：http://localhost:8080/swagger-ui/index.html
