Struts 2整合FCKeditor 上传图片

FCKEditor整合Struts 2上传图片会抛异常，这是因为Struts2的拦截器会和FCKeditor上传图片的过滤器会发生冲突，怎么解决这个问题？
最简单的一种解决方案就是重写Struts 2的StrutsPrepareAndExecuteFilter的doFilter(),具体代码如下：
package cn.sky.filter;

import java.io.IOException;

import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;

import org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter;

public class FCKFilter extends StrutsPrepareAndExecuteFilter {
    public void doFilter(ServletRequest req,ServletResponse res, FilterChain chain) throws IOException, ServletException {  
        HttpServletRequest request = (HttpServletRequest) req; 
        String URI = request.getRequestURI();
        String[] uriArray = URI.split("/fckeditor/editor/filemanager/connectors/");
        int arrayLen = uriArray.length;
        if (arrayLen >= 2) {
            chain.doFilter(req, res); 
        }else {
            super.doFilter(req, res, chain);  
        }
    }
}

Web.xml配置如下
<?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">
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<filter>
<filter-name>struts2</filter-name>
<filter-class>cn.sky.filter.FCKFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

</web-app>

就这样，Struts2 整合FCKeditor的问题解决了。
