（对不起，我的英语不好。）
我在两个地方使用IntelliJ。 （只需试用一下即可了解IDE）
我正在通过git Sharing gradle配置执行相同的spring boot项目。 我确实在两台PC上都设置了热交换（例如devtools，registry ..等）。
但是一个正常工作，另一个却不正常。
我做了如下测试：
运行spring boot应用程序
网页工作正常。
修改控制器代码，例如向控制台添加消息。
和嵌入式tomcat自动重启。
在这里，一台PC可以很好地工作（完美打印添加的消息）
但另一个没有。
tomcat自动重启后，相同的URL显示Whitelabel错误页面。
我对其进行了调查，发现两台计算机之间的某些日志有所不同。
