IDEA下tomcat启动后 server乱码，Tomcat Catalina Log和Tomcat Localhost Log乱码问题的解决

前言

不改的话，不影响使用，因为报错基本都是英文显示的。但是这几个中文字乱码的看着难受。

乱码的根本原因：

Windows系统的cmd是GBK编码的，所以IDEA的下方log输出的部分的编码也是GBK的，然而Tomcat 9.0 版本默认log输出是UTF-8编码的，采用了两种不同的编码方式就会导致乱码。

解决方案

修改Tomcat 日志输出为GBK编码

先打开tomcat的安装目录

编辑 conf 目录下的 logging.properties,把里面的UTF-8 通通改成 GBK,保存，重启Tomcat，即可生效。

修改IDEA为UTF-8编码

idea.exe.vmoptions、idea64.exe.vmoptions

修改idea.exe.vmoptions和idea64.exe.vmoptions这两个文件

分别在这两个文件的最后，添加一行 -Dfile.encoding=UTF-8

-Xms128m
-Xmx750m
-XX:ReservedCodeCacheSize=240m
-XX:+UseConcMarkSweepGC
-XX:SoftRefLRUPolicyMSPerMB=50
-ea
-Dsun.io.useCanonCaches=false
-Djava.net.preferIPv4Stack=true
-Djdk.http.auth.tunneling.disabledSchemes=""
-XX:+HeapDumpOnOutOfMemoryError
-XX:-OmitStackTraceInFastThrow

-Dfile.encoding=UTF-8

这个参数的作用是强制系统文件使用UTF-8编码,改完之后保存，重启IDEA即可。
