解决idea的控制台输出Tomcat日志乱码问题

乱码原因

由于window下的idea默认编码集都默认是GBK，而Tomcat目前版本是UTF-8，所以会出现乱码。

第一种解决方案：将Tomcat输出日志的编码改为GBK

在Tomcat的config目录下有一个logging.properties文件，文件中可以在五个地方设置编码，分别对应红色圆圈内五个日志输出文档（默认只选中了两个），将UTF-8的地方全改成GBK

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

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

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

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

java.util.logging.ConsoleHandler.level = FINE
java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter
java.util.logging.ConsoleHandler.encoding = UTF-8

第二种解决方案：更改idea控制台的编码为UTF-8

在idea的bin目录下有两个文件idea64.exe.vmoptions和idea.exe.vmoptions在文件第一行添加

-Dfile.encoding=UTF-8

更改之后

-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
