求助Java异常日志记录问题

Question

我现在在用Java写后台一些restful服务代码，整个应用程序分了多层。想问一下ERROR级别的日志是不是只需要在最上层记录就可以了？因为我想如果在下层的catch块中记录的话，可能会重复打印而导致性能问题和错误定位...

Yes, it is processed in your Servlet/Action layer. If the lower layer can handle it, it will be caught by itself. If it cannot be handled, it will be thrown upward.

The lower layer can also handle it without recording. It throws the error up and records the error information in catch. .
