Swagger2生成后台的API文档

添加依赖：

<!--Swagger2API生成-->
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger2</artifactId>
    <version>2.2.2</version>
</dependency>

<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger-ui</artifactId>
    <version>2.2.2</version>
</dependency>

编写实体类：

package com.frost.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
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
public class SwaggerConfig {

    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.frost"))// 指定扫描包下面的注解
                .paths(PathSelectors.any())
                .build();
    }
    // 创建api的基本信息
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("集成Swagger2构建RESTful APIs")
                .description("集成Swagger2构建RESTful APIs")
                .termsOfServiceUrl("https://www.baidu.com")
                .version("1.0.0")
                .build();
    }
}
