action擷取表單控制項值亂碼問題

配置過濾器

1、在web.xml檔案裡面加入

   <filter>  <filter-name>Set Character Encoding</filter-name>  <filter-class>com.web.util.SetCharacterEncodingFilter</filter-class>  </filter>    <filter-mapping>  <filter-name>Set Character Encoding</filter-name>  <url-pattern>/*</url-pattern>  </filter-mapping>

2、編寫過濾類

package com.web.util;import java.io.IOException;import javax.servlet.Filter;import javax.servlet.FilterChain;import javax.servlet.FilterConfig;import javax.servlet.ServletException;import javax.servlet.ServletRequest;import javax.servlet.ServletResponse;public class SetCharacterEncodingFilter implements Filter {public void destroy() {}public void doFilter(ServletRequest request,ServletResponse response,FilterChain chain)throws IOException,ServletException{request.setCharacterEncoding("GBK");chain.doFilter(request,response);}public void init(FilterConfig filterConfig) throws ServletException{}}
