记录Java学习过程中遇到的各种乱码问题！

Eclipse中文乱码

修改工作空间的编码方式：Window->Preferences->General->Workspace->Text file Encoding中的Others里选择需要的编码方式(如没有则直接输入)，然后保存。

IDEA中文乱码

设置文件编码格式：File=>Settings=>Editor=>File Encodings

Tomcat中文乱码

将文件conf\logging.properties中的编码类型更改为GBK。默认为UTF-8。修改位置如下：

############################################################
# Handler specific properties.
# Describes specific configuration info for Handlers.
############################################################

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 = GBK

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 = GBK

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 = GBK

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 = GBK

java.util.logging.ConsoleHandler.level = FINE
java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter
java.util.logging.ConsoleHandler.encoding = GBK
