Spring Boot 整合 Swagger，用于生成 Web API 文档。

版本信息：spring boot：2.7.11，swagger：2.9.2

错误原因：Springfox使用的路径匹配是基于AntPathMatcher的，而Spring Boot 2.6.X使用的是PathPatternMatcher

解决方案：

在application.yaml里配置：

spring:  mvc:    pathmatch:      matching-strategy: ant_path_matcher

治标不治本，我在使用的时候，最开始能够运行，上传到服务器上，又不能运行了，

新的解决方案

导入spring2.6.0后自身的doc接口工具类

                    org.springdoc            springdoc-openapi-ui            1.7.0        

编写配置文件

package com.yjq.miciweb.settings;import io.swagger.v3.oas.models.ExternalDocumentation;import io.swagger.v3.oas.models.OpenAPI;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;@Configurationpublic class SwaggerConfigruationSettings{//    创建Docket对象    @Bean    public OpenAPI springShopOpenApi(){        Info info = new Info()                .title("金融项目")                .version("v1.0")                .description("前后端分离")                .license(new License()                        .name("Apache 2.0")                        .url("http://222")                );        return new OpenAPI().info(info).externalDocs(new ExternalDocumentation()                .description("doc").url("http://222"));    }}
