springboot 2.7.0 配置swagger 3

第一步：pom.xml 添加依赖

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

第二步：在启动类Application中加上注解

package com.example.swagger;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import springfox.documentation.oas.annotations.EnableOpenApi;

@SpringBootApplication(exclude={DataSourceAutoConfiguration.class})
//exclude={DataSourceAutoConfiguration.class}：在没有连接数据库的情况下进行测试
@EnableOpenApi
public class SwaggerApplication {
    public static void main(String[] args) {
        SpringApplication.run(SwaggerApplication.class, args);
    }
}

第三步：配置接口文档config

package com.example.swagger.config;

import io.swagger.annotations.ApiOperation;
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.oas.annotations.EnableOpenApi;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;

@Configuration
@EnableOpenApi
public class SwaggerConfig {
    @Bean
    public Docket createRestApi(){
        return new Docket(DocumentationType.OAS_30)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class))
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo apiInfo(){
        return new ApiInfoBuilder()
                .title("Swagger3接口文档")
                .description("前后端分离的接口文档")
                .version("1.0")
                .build();
    }
}

第四步：在application.yml文件中加入语句

  mvc:
    pathmatch:
        matching-strategy: ant_path_matcher

2.7.0同样不支持swagger3的折衷配置，考虑升级Springboot版本或降级版本

除了参考中的springboot 2.6会有这样的问题，2.7也存在这样的问题，
