沧海小强通过本文主要向大家介绍了jsp页面传值乱码,jsp页面传值中文乱码,jsp页面之间传值乱码,jsp页面传值,两个jsp页面传值等相关知识,希望对您有所帮助,也希望大家支持linkedu.com www.linkedu.com
本文实例讲述了JSP页面传值乱码过滤方法。分享给大家供大家参考，具体如下：
1.过滤器类：
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 {
}
}
</div>
2.xml文件配置：
<?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">
<!--过滤器配置-->
<filter>
<filter-name>CharacterEncodingFilter</filter-name> <!--此名字与<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>
</div>
当我用<form>的默认提交方式提交时，此方法过滤不了，需要设置 method="post"，才可以过滤
希望本文所述对大家JSP程序设计有所帮助。
