日志文件默认是UTF-8是不会乱码的

#catalina 就是Tomcat服务器使用的 Apache实现的servlet容器的 名字。

#Tomcat的核心分为3个部分:
#（1）Web容器---处理静态页面；
#（2）catalina --- 一个servlet容器-----处理servlet;
#（3）还有就是JSP容器，它就是把jsp页面翻译成一般的servlet。
#IDEA部署到tomcat时，首先启动tomcat的catalina

#下面四个都是log（日志的编码）
#（2）catalina --- 一个servlet容器-----处理servlet;

#这个是控制台的编码（默认是UTF-8是乱码的）GBK是中文的
java.util.logging.ConsoleHandler.level = FINE
java.util.logging.ConsoleHandler.formatter = org.apache.juli.OneLineFormatter
java.util.logging.ConsoleHandler.encoding = GBK

控制台是指这里(这里是默认的UTF-8，会乱码的)不乱码就改成GBK

上面的日志编码分别是对应的编码格式默认UTF-8日志文件是不会出现乱码的改成GBK反而会乱码所以这里一定要谨慎
