ueditor是一个功能十分强大的在线文本编辑器，但是在ssh框架中，确切的说实在struts2中由于其拦截器需要对request，session对象进行重新封装，这个过程中会把request对象中保存的一些内容清空，所以会导致ueditor的上传功能获取不到需要上传的内容导致“未找到上传文件”的错误！
需要在web.xml中添加一个过滤器，并去掉struts2的在web.xml中配置的过滤器，此过滤器继承struts2的org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter，在过滤器实现类中判断是否请求的是编辑器的action，如果是执行自己的过滤器，这个过滤器的作用是：只针对ueditor的上传功能，如果不是，执行父类，也就是struts2的过滤器，。
package com.oracle.jingdong.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 EditorFilter extends StrutsPrepareAndExecuteFilter{
public void doFilter(ServletRequest req, ServletResponse res,
FilterChain chain) throws IOException, ServletException {
HttpServletRequest request = (HttpServletRequest) req;
String url = request.getRequestURI();
//System.out.println(url);
if (url.contains("/jsp/")) {
// System.out.println("使用自定义过滤器");
chain.doFilter(req, res);
}else{
// System.out.println("使用默认过滤器");
super.doFilter(req, res, chain);
}
}
}
web.xml
注意，如果有
1 <filter> 2 <filter-name>struts2</filter-name> 3 <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> 4 </filter>
