适合情况 -> 从jsp传入到action时的乱码情况,这里以GBK为例

1.建立一个用于转换编码的filter

文件位置举例:src.util.SetCharacterEncodingFilter.java

[java]view

 plaincopy

package 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;  

import javax.servlet.UnavailableException;  

/** 

 * Example filter that sets the character encoding to be used in parsing the 

 * incoming request 

 */  

public class SetCharacterEncodingFilter implements Filter {  

    /** 

     * Take this filter out of service. 

     */  

    public void destroy() {  

    }  

    /** 

     * Select and set (if specified) the character encoding to be used to 

     * interpret request parameters for this request. 

     */  

    public void doFilter(ServletRequest request, ServletResponse response,  

    FilterChain chain)throws IOException, ServletException {  

    request.setCharacterEncoding("gbk");  

    // 传递控制到下一个过滤器  

    chain.doFilter(request, response);  

    }  

    public void init(FilterConfig filterConfig) throws ServletException {  

    }  

}

2.修改web.xml,在struts的FilterDispatcher映射之前添加2个filter

[xhtml]view

 plaincopy

<?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">  

    <listener>  

        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  

    </listener>  

    <filter>  

        <filter-name>Set Character Encoding</filter-name>   

        <filter-class>util.SetCharacterEncodingFilter</filter-class>   

    </filter>   

    <filter-mapping>   

        <filter-name>Set Character Encoding</filter-name>  

        <url-pattern>/*</url-pattern>   

    </filter-mapping>  

    <filter>   

        <filter-name>struts-cleanup</filter-name>   

        <filter-class>org.apache.struts2.dispatcher.ActionContextCleanUp</filter-class>   

    </filter>  

    <filter-mapping>  

        <filter-name>struts-cleanup</filter-name>  

        <url-pattern>/*</url-pattern>  

    </filter-mapping>  

    <filter>  

        <filter-name>struts2</filter-name>  

        <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>  

    </filter>  

    <filter-mapping>  

        <filter-name>struts2</filter-name>  

        <url-pattern>/*</url-pattern>  

    </filter-mapping>  

</web-app>
