在你的tomcat路径下，参考我的：D:\Tomcat 6.0\conf\server.xml
添加：URIEncoding ="UTF-8" 完整如下：
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" URIEncoding ="UTF-8"/>
添加：URIEncoding ="UTF-8" 完整如下：
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" URIEncoding ="UTF-8"/>
