过滤器：

import javax.servlet.FilterConfig;
import javax.servlet.ServletException;

Answer 2

我加上配置文件中红色字体部分后，无法登陆：
HTTP Status 404 - /consumption/login.action--------------------------------------------------------------------------------type Status reportmessage /consumption/login.actiondescription The requested resource (/consumption/login.action) is not available.去掉那部分后一切正常。乱码问题困扰了半天，希望大家帮帮忙。

Answer 3

<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>
struts2只需要在web.xml里面配置这个就行了
包记得导入

Answer 4

response.setContentType("text ml;charset=" + encoding); 
不知道这里是拷错了还是原本就是这样子写的。。text/html?忘了

Answer 5

</filter> 
<filter-mapping> 
<filter-name>encodingFilter </filter-name> 
<url-pattern>/* </url-pattern> 
</filter-mapping> 
把这个放在 
<filter-mapping>      
  <filter-name>struts2 </filter-name>      
  <url-pattern>*.ph </url-pattern>      
</filter-mapping>
的上面

Answer 7

tmpFile是什么? LZ可否先尝试把多余的FILTER都去掉 只用一个STRUTS2来看看捏?

Answer 8

在配置文件中把红色字体部分去掉没有问题的。现在登录后又报另外一个错误：样式表中没有包含文档元素，样式表可能是空的，或它可能不是一个标准的xml文档。配置文件如下：

</web-app>我去掉红色部分一切正常

Answer 9

你的过滤器里进行了什么操作? 你确认是因为该过滤器导致了这些原因么？ 不是因为下面那些Servlet的配置?
LZ先确认是否是因为你的encodingFilter出问题 先把STRUTS2去掉 看看还好使不(启动是否有错误信息?)
如果有错误信息的话 那就说明你这个过滤器可能有问题 如果没有的话 那就能说明他们两个可能冲突 

Answer 10

过滤器的代码我贴在二楼了。去掉STRUTS2后所有的功能无法使用。我不确定是什么东西导致这些原因，所以才来请教。

Answer 11

我的意思是 先把STRUTS2去掉 然后看启动的时候有没有异常信息 如果有的话 那就把目标锁定到你编码过滤器上对了 我记得struts2能设置字符集的啊..

你的struts2的版本 该高一点，struts2自动能出来乱码呢，比如是struts2.1.6版本以上就不用处理乱码呢

Answer 18

我是楼主。这个问题解决了一半，请大家继续。
web.xml:
<filter>
<filter-name>sfsdfdsfsdf</filter-name>
<filter-class>com.zoyechina.consumption.tool.CharsetFilter</filter-class>
  <init-param>
          <param-name>charset</param-name>
          <param-value>GBK</param-value>
      </init-param>
</filter>
<filter-mapping>
        <filter-name>sfsdfdsfsdf</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
过滤器继承struts2的FilterDispatcher ：
public class CharsetFilter extends FilterDispatcher { 
private String charset;
    public void destroy() {
    }
    public void doFilter(ServletRequest arg0, ServletResponse arg1,
            FilterChain arg2) throws IOException, ServletException {
        arg0.setCharacterEncoding(charset);
        arg1.setCharacterEncoding(charset);
        arg2.doFilter(arg0, arg1);    }    public void init(FilterConfig arg0) throws ServletException {
             this.charset = arg0.getInitParameter("charset");    }
} 
页面编码，server.xml设置成UTF-8（server.xml设置见14楼）。
现在的结果：在后台获取中文没有问题了，但是用ajax验证的时候取到的还是乱码。
loadXMLDoc("checknameCardType.action?cardName="+cardname,checkReturn);后台取cardName时候还是乱码。

Answer 19

问题已经解决，谢谢各位的回答。
在表单中传递的中文乱码解决办法如22楼所说。
ajax传递中文乱码：
在js中加上：cardname=encodeURI(encodeURI(cardname));//cardname为你要传递的参数。
服务端取值：用java.net.URLDecoder.decode(cardname,"UTF-8");解析。松了一口气啊。

Answer 20

Struts2 的编码问题刚好可以看看我刚刚写的 Blog，其实 Struts2 利用了 Filter ，其已经将
字符编码过滤器的功能集成到 StrutsPrepareAndExecuteFilter 里面了，只是 Struts2.1.8 之前
有个小 bug  
http://blog.csdn.net/Purking/archive/2010/01/27/5263363.aspx
