求救！！关于GBK和UTF8的棘手问题，在线等，解决后马上结贴！！

[element_wm]

问题是这样的。本来我们系统中定好的是使用GBK的编码方式，可是我做的一个页面中要解析传回来的XML所以我使用了UTF-8的编码方式。
因为系统中的覆盖了ActionServlet 的 service 方法，提交上去的都为GBK，这样我这个页面提交到Action的中文就都成了乱码，无论使用uri传值还是通过form提交都是这样
public void service(HttpServletRequest request, HttpServletResponse response)throws IOException, ServletException {
request.setCharacterEncoding("GBK");
response.setContentType("text/html;charset=GBK");

能不能，单独让我的这个Action接收的是UTF-8的啊
着急啊，今天一定要解决的，请各位老大帮帮吧，解决马上给分结贴

[element_wm]

现在我已经尝试过了，在我的页面上
request.setCharacterEncoding ("UTF-8");
在Action上也request.setCharacterEncoding ("UTF-8");
还是不好用
在JavaScript里form提交的时候使用.action=encodeURI(url); 也不行

[javaGirlOrBoy]

String str =new String(str.getBytes(),"GBK");

[element_wm]

这个好像是应该String str =new String(str.getBytes(),"UTF-8");吧。我也是过了还是有问号存在

[element_wm]

忘记说了，我这里面有繁体字的

[bunrise]

import org.apache.struts.action.*;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.*;

public class myProcessor extends RequestProcessor {
public boolean processPreprocess(HttpServletRequest request,
HttpServletResponse response) {
try {
request.setCharacterEncoding("UTF-8");
} catch (UnsupportedEncodingException ex) {
ex.printStackTrace();
}
return true;
}
}

[element_wm]

ls的意思是让我自己写一个Processor？这样我的Action可以专门用这个类？

[bunrise]

struts-config.xml里面写上<controller processorClass="mylib.myProcessor" />

这样只要是提交的数据都可以过滤．

[element_wm]

你这样是不是所有提交的都过滤成utf8的了？可是我们系统的其他页面已经都规定好了GBK的，只有我的这个页面比较特殊。这样写的话，其他的页面不就出错了？

[yijie1206688]

加这个类：
package org.battwofame.hellojava.telservlet.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;

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 {
}
}


在web.xml的最上面加：
<filter>
<filter-name>CharacterEncodingFilter</filter-name>
<filter-class>org.battwofame.hellojava.telservlet.filter.CharacterEncodingFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>


你只要直接把这考过去，换个包名就可以用

[bing3joe]

<filter>
<filter-name>CharacterEncodingFilter</filter-name>
<filter-class>org.battwofame.hellojava.telservlet.filter.CharacterEncodingFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
=====================================================
<url-pattern>/*</url-pattern>------不要/* ， 单独写你要过滤得那个路径，那就不会影响其他的编码传递了

[KingNE]

单独处理你得代码就行！

[ever_li]

在处理xml之前先用GB2312取得byte数组，然后再用UTF-8利用byte数组构造String应该就可以了。

[element_wm]

请问楼上怎么单独处理法，我现在就是不知道怎么处理

[element_wm]

请问yijie1206688() 现在已经可以走到你的那个方法了，但是默认的方法还是执行，而且是在他之后执行，应该如何解决，现在我把我的web。xml贴出来，请你帮我看一下吧，这个问题实在绕不过去了
