Due to the introduction of package commands and other processing in JSP, the source code of the rendered page contains many line breaks. There are many ways to solve the problem in the past, such as 1. Pay attention to the format in the source code,

DebuggingInterceptor: the interceptor processes the seventh position of defaultStack. It can be called for debugging. I personally think that although the interceptor contains the most code, it is the most useless Interceptor. This interceptor
