Tool class for printing records written to files on the imitation log4j Console

Background:

This afternoon, when I write a multi-threaded test program reader writer-writer first (this article will be published later, I want to see the printing result of the console, but you know, the eclipse console can only save part of the data. Log4j configuration is a little tricky.

So I wrote this tool class that can write local files myself:

 

Functions implemented by the tool class:

1. Follow[Time-call class-call method-row number of the call method-message]Press enter to write the file

2. One log file every day

If you don't talk about it, go to the Code:
