本地使用Tomcat啟動項目的時候，出現亂碼，報錯情況如下：

一共做了三件事：
1. 修改Tomcat配置文件，增加UTF-8編碼
更改Tomcat的conf文件夾下的service.xml配置，增加URIEncoding="UTF-8"，具體如下：
<Connector port="8080" protocol="HTTP/1.1" ? connectionTimeout="20000" ? redirectPort="8443" URIEncoding="UTF-8"/>
發現啟動情況仍無改變
2. 更改idea配置，設置編碼為UTF-8
打開Setting，搜索File Encoding，修改配置如下圖：
image
發現啟動情況仍無改變
3. 修改tomcat的conf下的logging.properties中的參數
將java.util.logging.ConsoleHandler.encoding = UTF-8
改為
java.util.logging.ConsoleHandler.encoding = GBK
ok了。
