Question

2019-12-17 12:43:20.834 ERROR 4644 --- [           main] o.s.boot.SpringApplication               : Application run failed

以上就是异常栈的主要信息，从中我现在已经看不出任何有效信息了。
怀疑过mappers文件夹中mapper.xml的编码问题，经vscode、notepad++等工具检查确认了编码的确是UTF-8 with NO BOM，所有mapper都是generate生成的，打包用的jdk试过了8和11，都一样会报这个错。

这张图片是打包时的信息，可见打包过程中的test也是OK的。

delete from sys_user_role where user_id not in ( ?, ?, ? )

其中这一行代码是我写在一个Configuration中的，是为了方便测试时清除无效数据使用，这个代码就是调用了mapper中的sql。

综上所述，求大佬救命！！！

最后问题解决了，是因为，resources下没有mybatis的配置文件。为啥没有配置文件就不能用命令行启动jar包，我也不知道。采纳的答案是因为解决时就只有一个回答........
