过滤器配置
可以改下面这个文件,加入一个URIEncoding="GBK"
X:/Tomcat 5.5/conf/Server.xml
- <filter>
- <filter-name>encoding</filter-name>
- <filter-class>
- filter.FilterEncoding
- </filter-class>

- <param-name>encoding</param-name>
- <param-value>gbk</param-value>

- </filter>
<filter> <filter-name>encoding</filter-name> <filter-class> filter.FilterEncoding </filter-class> <init-param> <param-name>encoding</param-name> <param-value>gbk</param-value> </init-param></filter>

可以改下面这个文件,加入一个URIEncoding="GBK"

- redirectPort="8443"
- minSpareThreads="25"
- connectionTimeout="30"
- maxThreads="150"
- maxSpareThreads="75"
- URIEncoding="GBK">
<Connector port="8080" redirectPort="8443" minSpareThreads="25" connectionTimeout="30" maxThreads="150" maxSpareThreads="75" URIEncoding="GBK">jsp头文件
- <%@ page contentType="text/html;charset=gbk"%>
<%@ page contentType="text/html;charset=gbk"%>//此处的charset的值要和web.xml里的 <param-value></param-value>值一样
