Tomcat中配置URIEncoding="UTF-8"来处理中文的处理
打开 server.xml 文件，更改两个地方。
配置一：添加 URIEncoding="UTF-8"
<Connector URIEncoding="UTF-8" connectionTimeout="20000" port="8081" protocol="HTTP/1.1" redirectPort="8443"/>
配置二：添加 URIEncoding="UTF-8"
<Connector URIEncoding="UTF-8" port="8009" protocol="AJP/1.3" redirectPort="8443"/>
配置后重启tomcat。
