struts工程form表单提交乱码问题　　谢谢了用了　几种方法都不行啊
public   class   MyRequestProcessor   extends   RequestProcessor{
  public   MyRequestProcessor(){}
  protected   boolean   processPreprocess(HttpServletRequest   request,
      HttpServletResponse   response){
    try{
      request.setCharacterEncoding( "GBK ");//在此设置字符集
    }
    catch(Exception   ex){
      System.out.println( "字符集设置失败 ");
    }
    return   true;
  }
}

在struts-config.xml中
<controller   processorClass= "com.ccu.bbs.requestprocessor.MyRequestProcessor "   />


就是不好用　是什么原因呢？

------解决方案--------------------
package app;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.RequestProcessor;

public class MyRequestProcessor extends RequestProcessor
{
public MyRequestProcessor() {}
protected boolean processPreprocess(HttpServletRequest request,HttpServletResponse response)
{
try
{
request.setCharacterEncoding( "gb2312 ");
}catch (Exception ex)
{
ex.printStackTrace();
}
return true;
}


}
改成gb2312
------解决方案--------------------
用过滤器吧
------解决方案--------------------
应改没有问题的。。。
你重新启动一下在看看
------解决方案--------------------
用这个方法吧：

public String getStr(String str)
{
try
{
byte[] bt = str.getBytes( "ISO8859-1 ");
String temp = new String(bt);
}catch(Exception e)
{
}
return temp;
}
------解决方案--------------------

解决页面上的中文显示或者Form提交会乱码的问题，在web.xml加入字符集过滤，如下：
<filter>
<filter-name> charsetFilter </filter-name>
<filter-class> com.company.filter.CharsetFilter </filter-class>
<init-param>
<param-name> charsetEncodingType </param-name>
<param-value> gb2312 </param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name> charsetFilter </filter-name>
<url-pattern> /* </url-pattern>
</filter-mapping>
对应的com.company.filter.CharsetFilter类如下：

package com.company.filter;

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 org.apache.commons.lang.StringUtils;

public class CharsetFilter implements Filter{

private static final String characterEncodingType= "charsetEncodingType ";
private static final String defaultCharsetEncode= "gb2312 ";
private String charsetEncode=null;

public void init(FilterConfig arg0) throws ServletExceptio
