由于项目需要，springboot项目需基于jdk17环境开发，结合nacos2.0.3、分布式事务seata-server-1.7.1、分库分表shardingSphere5.2.1等，项目启动过程中出现的问题解决方式小结。

问题一：

 编辑项目启动配置：Edit Configurations:

注意：刚打开没有Add VM options输入框，可快捷键Alt+V输入：

--add-opens java.base/java.lang.reflect=ALL-UNNAMED，如下所示：

 问题二：（此问题研究了好久，尝试了网上提到的各种解决办法都没成功，最终还是结合自己的经验判断搞定）

看到错误中显示shardingsphere未成功代理到数据源。
开始是判断可能数据库连接配置可能有问题，开始测试，修改一个错误连接，看到错误为不能找到数据源，这说明已经可以连接数据源了，只是连接数据源后可能哪边导致了问题。
经过多次查看控制台信息，发现部分还是跟seata相关，通过在nacos中多次引入通用seata配置还是提示未成功代理数据源，于是通过查看以前成功启动的seata配置，讲通用seata配置移植到开发环境yml配置中，成功启动。
整体上看，主要原因是seata配置未能成功加载导致，seata跟shardingsphere有关联。具体关联后续再细致研究。

注意：在调试sql执行过程中发现sql日志打印不了，最终发现未配置logback-spring.xml日志导致。
