Spring boot 读模块项目升级为spring cloud 项目步骤以及问题

1.结构说明

bean 模块  ，public 模块， client 模块， erp模块，system 主模块。

2.环境说明以及pom

原本环境                      新环境

mysql 5.7   --------------  mysql  8.0

maven 3.9.6

jdk  8          ------------     jdk17

spring boot  2.5.3  ------  spring boot 3.0.2

knife4j  3.0  ------------ knife4j  4.5

               ---------  spring cloud 2022.0.0.0

3.在更换环境可能会出现的问题

  3.1  错误 ：Waited 3000 milliseconds (plus 12 milliseconds, 340600 nanoseconds delay

    解决：在运行 Nacos 之前，请确保你打开了所需的端口（8848），以确保 Nacos 可以正常工作。我开启9848和9849两个端口后，问题解决。

 3.2  错误 ： Relying upon circular references is discouraged and they are prohibited by default

  解决：可以在application.xml配置文件中的spring下添加配置来解决问题，即：

 srping :

      main:
        #    解决升级Spring Boot2.6后,因依赖循环引用导致启动时报错的问题
         allow-circular-references: true

3.3  错误 ：Type javax.servlet.http.HttpServletRequest not present 

解决： 可能是版本不匹配了  ，可以换成以下的

<dependency><groupId>com.github.xiaoymin</groupId><artifactId>knife4j-openapi3-jakarta-spring-boot-starter</artifactId><version>4.5.0</version>
</dependency>
//  加上他 之前使用的 @Api 等注解就不需要替换了
<dependency><groupId>io.swagger</groupId><artifactId>swagger-annotations</artifactId><version>1.6.6</version>
</dependency>

 3.4  错误 ： org.springframework.cloud:spring-cloud-dependencies:pom:2022.0.0.0 was not found in https://maven.aliyun.com/repository/public during a previous attempt. This failure was cached in the local repository and resolution is not reattempted until the upda

  解决 ：maven 中的 settings.xml 文件 远程仓库改成以下配置

  

  <mirrors><mirror><id>nexus-aliyun</id><mirrorOf>central</mirrorOf><name>Nexus aliyun</name><url>http://maven.aliyun.com/nexus/content/groups/public</ur1></mirror><!--    阿里仓库--><mirror><id>alimaven</id><name>aliyun maven</name><url>https://maven.aliyun.com/repository/public</url><mirrorOf>central</mirrorOf></mirror></mirrors>

项目jdk设置正确
