（下边有2.x的配置，不过没试过

配置

<!--        生成接口文档-->
        <dependency>
            <groupId>org.springdoc</groupId>
            <artifactId>springdoc-openapi-starter-webmvc-ui</artifactId>
            <version>2.5.0</version>
        </dependency>
        <dependency>
            <groupId>org.springdoc</groupId>
            <artifactId>springdoc-openapi-starter-webmvc-api</artifactId>
            <version>2.5.0</version>
        </dependency>

 代码

 SwaggerConfig.java

package com.example.config;


import io.swagger.v3.oas.models.ExternalDocumentation;
import io.swagger.v3.oas.models.OpenAPI;
import io.swagger.v3.oas.models.info.Contact;
import io.swagger.v3.oas.models.info.Info;
import io.swagger.v3.oas.models.info.License;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class SwaggerConfig {
    @Bean
    public OpenAPI springShopOpenAPI() {
        return new OpenAPI()
                .info(new Info().title("Spring Boot 中使用 Swagger UI 构建 RESTful API")
                        .contact(new Contact())
                        .description("信息管理平台提供的 RESTful API")
                        .version("v1.0.0")
                        .license(new License().name("Apache 2.0").url("http://springdoc.org")))
                .externalDocs(new ExternalDocumentation()
                        .description("外部文档")
                        .url("https://springshop.wiki.github.org/docs"));
    }
}

application.properties中配置

# 开启OpenApi接口
springdoc.api-docs.enabled: true
# 开启swagger界面，依赖OpenApi，需要OpenApi同时开启
springdoc.swagger-ui.enabled: true

 SwaggerConfig.java

package com.example.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;

@Configuration      //告诉spring这是一个配置类
@EnableSwagger2     //启用swagger2功能
public class SwaggerConfig {
    /*
    配置swagger2相关的bean
     */
    @Bean
    public Docket createRestApi(){
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                // com包下的所有api都较给swagger2管理
                .apis(RequestHandlerSelectors.basePackage("com"))
                .paths(PathSelectors.any()).build();
    }
    /*
    此处主要是api文档页面显示信息
     */
    private ApiInfo apiInfo(){
        return new ApiInfoBuilder()
                .title("演示项目api")       //标题
                .description("演示项目")        //描述
                .version("1.0")     //版本
                .build();
    }
}

————注意

如果springboot是2.6以后的版本，需要在application.properties中加入以下配置

spring.mvc.pathmatch.matching-strategy=ant_path_matcher
