直接部署kindeidtor在tomcat下可以正确的上传图片，当和struts2整合（就是想把原来写在jsp中的代码写在一个类中）到一块的时候上传不成功，debug时候在List items =upload.parseRequest(request);总体是items为空，奇怪的就是在jsp上就可以和struts2整合就不行，搞了半天终于找到方案:
-----------------------------------------------------------------------------------------------参考文章:http://auzll.iteye.com/blog/919981
一、项目基本环境：struts2等
二、基本需求&问题：需要自己写程序调用common-fileupload来处理上传的文件，但在代码调用upload.parseRequest(request)来处理时，返回了空的items
三、处理方法1、按照网上找到对该问题的相关处理方法： struts2@Controller@SuppressWarnings("unchecked")publicclass ImageManagerAction extendsActionSupport {

《《《《《《《《《《《《《《《《 第二个问题json返回结果 》》》》》》》》》》》》》》》》》》》》》
上传返回结果json字符串本想用struts2的方式返回，但是失败(KindEditor脚本原因)改用上述方式成功.
我在使用时,是用jsp页面处理的上传过程,并没有做此复杂处理,最简单的修改方式:
(1)建立filter拦截器;(2)在web.xml设置对处理上传的jsp页面的filter(注:)
代码如下:
(1)UploadFilter:
package com.utils.contentfilter;
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 javax.servlet.http.HttpServletRequest;
import org.apache.struts2.dispatcher.StrutsRequestWrapper;
public class UploadFilter implements Filter {
public void destroy() {
}
public void doFilter(ServletRequest request, ServletResponseresponse,
FilterChain chain) throws IOException, ServletException {
chain.doFilter(new StrutsRequestWrapper((HttpServletRequest)request), response);
}
public void init(FilterConfig filterConfig) throws ServletException{
}
}
(2) web.xml中设置:
uploadsss
com.utils.contentfilter.UploadFilter
uploadsss
/upload_json.jsp
