idea中tomcat控制台输出中文乱码问题的解决

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 8.5 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。

方法1：修改Tomcat 日志输出为GBK编码

tomcat的安装目录编辑 conf 目录下的 logging.properties

1catalina.org.apache.juli.AsyncFileHandler.level = FINE
1catalina.org.apache.juli.AsyncFileHandler.directory = ${catalina.base}/logs
1catalina.org.apache.juli.AsyncFileHandler.prefix = catalina.
#1catalina.org.apache.juli.AsyncFileHandler.encoding = UTF-8
1catalina.org.apache.juli.AsyncFileHandler.encoding = GBK

2localhost.org.apache.juli.AsyncFileHandler.level = FINE
2localhost.org.apache.juli.AsyncFileHandler.directory = ${catalina.base}/logs
2localhost.org.apache.juli.AsyncFileHandler.prefix = localhost.
#2localhost.org.apache.juli.AsyncFileHandler.encoding = UTF-8
2localhost.org.apache.juli.AsyncFileHandler.encoding = GBK

3manager.org.apache.juli.AsyncFileHandler.level = FINE
3manager.org.apache.juli.AsyncFileHandler.directory = ${catalina.base}/logs
3manager.org.apache.juli.AsyncFileHandler.prefix = manager.
#3manager.org.apache.juli.AsyncFileHandler.encoding = UTF-8
3manager.org.apache.juli.AsyncFileHandler.encoding = GBK

4host-manager.org.apache.juli.AsyncFileHandler.level = FINE
4host-manager.org.apache.juli.AsyncFileHandler.directory = ${catalina.base}/logs
4host-manager.org.apache.juli.AsyncFileHandler.prefix = host-manager.
#4host-manager.org.apache.juli.AsyncFileHandler.encoding = UTF-8
4host-manager.org.apache.juli.AsyncFileHandler.encoding = GBK

java.util.logging.ConsoleHandler.level = FINE
java.util.logging.ConsoleHandler.formatter = org.apache.juli.OneLineFormatter
#java.util.logging.ConsoleHandler.encoding = UTF-8
java.util.logging.ConsoleHandler.encoding = GBK

方法2：修改IDEA为UTF-8编码

打开 idea的安装目录
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
改完之后保存，重启IDEA即可。

这个参数的作用是强制系统文件使用UTF-8编码
