1）添加knife4j的依赖

<dependency><groupId>com.github.xiaoymin</groupId><artifactId>knife4j-spring-boot-starter</artifactId><version>3.0.2</version>
</dependency>

SpringBoot的版本：

<parent><artifactId>spring-boot-starter-parent</artifactId><groupId>org.springframework.boot</groupId><version>2.7.3</version>
</parent>

2）添加knife4j的配置类

@Configuration
public class Knife4jConfig {@Beanpublic Docket docket() {ApiInfo apiInfo = new ApiInfoBuilder().title("测试项目接口文档").version("2.0").description("测试项目接口文档").build();Docket docket = new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo).select().apis(RequestHandlerSelectors.basePackage("com.github.xjs.controller")).paths(PathSelectors.any()).build();return docket;}}

3）application.yml中设置springmvc的路径匹配规则

spring:mvc:pathmatch:matching-strategy: ant_path_matcher

done!
