2、java.lang.NoClassDefFoundError: ch/qos/logback/core/util/StatusPrinter2
原因:Maven包冲突
解决:https://blog.csdn.net/qq_38254635/article/details/141019735
3、Logging system failed to initialize using configuration from ‘null’
原因:缺少 logback-spring.xml 配置文件

从目前的报错来看,直接从JAVA8往JAVA17/21去升级,一定是困难重重的,而且很多的组件都会出现不适配的情况。
所以,结合目前的情况,建议放弃直接改造。
而是使用JAVA17直接搭建一套空白脚手架,然后将业务代码分类填充,就会方便很多,而且会更快。
空白脚手架注意内容:拦截器,过滤器,事务控制,跨域,加解密,加签验签,权限,session控制,通用异常处理机制,数据库驱动,Mybatis组件,定时任务quartz,日志管理,redis组件,配置文件jasypt加密,RABC,工具类等等。
OK,就这些吧。
有什么不对的还望指正,书写不易,觉得有帮助就点个赞吧!☺☺☺
