项目需要用swagger自动生成接口文档，因此记录一下
一、普通SpringBoot项目中
首先在pom.xml中引入jar包

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

然后在最外层创建SwaggerConfig.java

package com.ca.web.core.config;

import java.util.ArrayList;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import com.ca.common.config.RuoYiConfig;
import io.swagger.annotations.ApiOperation;
import io.swagger.models.auth.In;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
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.AuthorizationScope;
import springfox.documentation.service.Contact;
import springfox.documentation.service.SecurityReference;
import springfox.documentation.service.SecurityScheme;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spi.service.contexts.SecurityContext;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

/**
 * Swagger2的接口配置
 * 
 * @author ruoyi
 */
@Configuration
@EnableWebMvc
@EnableSwagger2
public class SwaggerConfig
{


    /**
     * 创建API
     */
    @Bean
    public Docket createRestApi()
    {
        return new Docket(DocumentationType.SWAGGER_2)
                // 设置哪些接口暴露给Swagger展示
                .select()
                // 扫描所有有注解的api，用这种方式更灵活
                .apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class))
                .build();
    }
}

二、若依中
若依将swagger封装在框架中

运行前端页面后在系统工具中找系统接口
