想了解启动Tomcat时出现大量乱码的解决办法的相关内容吗，正在自学java的菜鸟在本文为您仔细讲解启动Tomcat乱码的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：启动Tomcat乱码的解决办法,启动Tomcat乱码，下面大家一起来学习吧。

启动Tomcat乱码

1. 在 tomcat 的启动窗口打印的启动信息中包含了大量的中文乱码，虽然这些对 tomcat 本身的使用没有任何影响，但却非常碍眼，影响视觉效果!

2. 对于乱码问题，原因是字节流解码为字符串时，使用了错误的字符集(和编码所用字符集不一致) !

我们找到 tomcat 目录下的 config 子目录中，找到"logging.properties" 文件，打开这个文本文件，找到如下配置项：

java.util.logging.ConsoleHandler.encoding = UTF-8

将 UTF-8 修改为 GBK，修改后的效果为：

java.util.logging.ConsoleHandler.encoding = GBK

保存后，重启 tomcat
