任何人都可以解释。
我正在使用Netbeans并致力于Spring Boot MVC + thymeleaf + mongodb。
当我修改一些代码并保存时，Netbeans会自动编译代码，然后刷新浏览器以查看更改。一切几乎都能正常工作，但是在我快速修改和多次保存期间，有时我会留下语法错误或任何东西，netbeans会再次自动编译，当我刷新浏览器时会出现销售500错误，但是我可以解决我的错误，而不是再次保存netbeans编译我刷新页面，然后一切正常。但是奇怪的是，在netbeans控制台上，它每隔2秒就会用下面的错误堆栈跟踪填充Netbeans输出窗口。
只有在前500个错误之后才会发生。
