一、引入包，pom.XML配置如下

      <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>

二、編寫配置類

package com.anjiplus.template.gaea.business.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;

/**
 * @Author 尹明能
 * @Date 2022/4/12 12:52
 * @Version 1.0
 */
@EnableSwagger2
@Configuration
public class Swagger2Config {

    @Bean
    public Docket createRestApi() {
         return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.anjiplus.template.gaea.business.modules"))
                .paths(PathSelectors.any())
                .build();
    }
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("利用Swagger2構建RESTful APIs")
                .description("swagger demo")
                .termsOfServiceUrl("")
                .version("1.0")
                .build();
    }
}

三、攔截規則配置，否則會出現swagger開啟白屏問題

這個是我自己寫的規則，如果使用spring securiry參考其他方式

kip-authenticate-urls: /gaeaDict/all, /login, /static, /file/download/, /index.html,/swagger,/webjars,/v2,/swagger-resources,/swagger-ui.html, /favicon.ico, /reportShare/detailByCode,/reportDashboard

四、控制器增加@API註解
