Question

我正在使用springboot 1.2.7进行新项目，并且在启动过程中很难找到配置错误。每次我有错误，它都不会显示在控制台中，我只有：

我尝试放置一些断点，但找不到真正导致此错误的内容。

在这种情况下，当我在服务中添加“@Transactional”时出现此错误... 如果我删除@Transactional，则正常启动springboot。

对于所有conf问题都有这个问题，它使我的调试需要很长时间才能找到初始错误。

我正在使用logback，日志级别设置为DEBUG。

谢谢！

找到解决方案：我需要在我的tomcat启动命令中添加-Ddebug，它会在启动过程中显示错误。

启动时无法调试配置错误
