本地使用Tomcat啟動(dòng)項(xiàng)目的時(shí)候，出現(xiàn)亂碼，報(bào)錯(cuò)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(fā)現(xiàn)啟動(dòng)情況仍無(wú)改變

2. 更改idea配置，設(shè)置編碼為UTF-8

打開(kāi)Setting，搜索File Encoding，修改配置如下圖：

idea修改編碼.png

發(fā)現(xiàn)啟動(dòng)情況仍無(wú)改變

3. 修改tomcat的conf下的logging.properties中的參數(shù)

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

改為

java.util.logging.ConsoleHandler.encoding = GBK

ok了。
