JSP頁面傳值亂碼過濾方法_JSP編程

本文執行個體講述了JSP頁面傳值亂碼過濾方法。分享給大家供大家參考，具體如下：

1.過濾器類：

package com.token.t1;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 CharacterEncodingFilter 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 arg0) throws ServletException {  }}

2.xml檔案配置：

<?xml version="1.0" encoding="UTF-8"?><web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xsi:schemaLocation="http://java.sun.com/xml/ns/javaee   http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"><!--過濾器配置-->　　<filter>    <filter-name>CharacterEncodingFilter</filter-name>   <!--此名字與<filter-mapping>下<filter-name>相同即可 -->    <filter-class>com.token.t1.CharacterEncodingFilter</filter-class>  </filter>  <filter-mapping>    <filter-name>CharacterEncodingFilter</filter-name>    <url-pattern> /* </url-pattern>  </filter-mapping>  <display-name></display-name>  <welcome-file-list>    <welcome-file>index.jsp</welcome-file>  </welcome-file-list></web-app>

當我用<form>的預設提交方式提交時，此方法過濾不了，需要設定 method="post"，才可以過濾

希望本文所述對大家JSP程式設計有所協助。
