注释掉2.0引入的俩包

直接引入3.0

  <dependency><groupId>io.springfox</groupId><artifactId>springfox-boot-starter</artifactId><version>3.0.0</version></dependency>

swagger配置文件粘贴即用哦

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;@EnableSwagger2
@Configuration
public class SwaggerConfig {@Beanpublic Docket createRestApi() {return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo()).select()//TODO 改为你项目使用的controller包目录.apis(RequestHandlerSelectors.basePackage("com.example.controller")).paths(PathSelectors.any()).build();}//构建api的详细信息方法private ApiInfo apiInfo() {return new ApiInfoBuilder()//页面标题.title("xx接口文档")//版本号.version("1.0")//描述.description("swagger3.0的为基础的文档哟").build();}
}

最后配置文件改变mvc匹配规则即可

spring:mvc:pathmatch:matching-strategy: ant_path_matcher

最后

swagger2.0访问地址是：
