Struts2 urlrewrite + kindeditor 上传图片时request为null问题
采用struts2? 加上了? urlrewrite? 后 web.xml?里面配置变成了这样
?
?
?<filter-mapping>
??<filter-name>struts2</filter-name>
??<url-pattern>/*</url-pattern>
??<!-- 重新必须加的 -->
??<dispatcher>FORWARD</dispatcher>
??<dispatcher>REQUEST</dispatcher>
??<!-- <dispatcher>INCLUDE </dispatcher>? -->
?</filter-mapping>
?
?但是问题就来了 url 重写 是实现了 但是 /* 是不能完成kindeditor? 当中的upload_json.jsp上传的
?
upload_json.jsp 的上传? 是需要 *.action
?
?
怎么解决呢 办法来了
?
重写一个jsp用作上传
?
?
如下：
?
<%@ page language="java" pageEncoding="GBK"%>
<%@page
?import="java.util.*,java.io.*,org.apache.struts2.dispatcher.multipart.MultiPartRequestWrapper,java.util.concurrent.locks.*"%>
<%
?//Struts2? 请求 包装过滤器???
?MultiPartRequestWrapper wrapper = (MultiPartRequestWrapper) request;
?// 获得上传的文件名????
?String fileName = wrapper.getFileNames("imgFile")[0];
?//获得未见过滤器????
?File file = wrapper.getFiles("imgFile")[0];
?//----------- 重新构建上传文件名----------------------???
?final Lock lock = new ReentrantLock();
?String newName = null;
?lock.lock();
?try {
??//加锁为防止文件名重复????
??newName = System.currentTimeMillis()
????+ fileName.substring(fileName.lastIndexOf("."),
??????fileName.length());
?} finally {
??lock.unlock();
?}
?//------------ 锁结束 -------------???
?//获取文件输出流????
?FileOutputStream fos = new FileOutputStream(request.getSession()
???.getServletContext().getRealPath("/")
???+ "ke_upload\" + newName);
?//设置 KE 中的图片文件地址????
?String newFileName = request.getScheme() + "://"
???+ request.getServerName() + ":" + request.getServerPort()
???+ request.getContextPath() + "/ke_upload/" + newName;
?byte[] buffer = new byte[1024];
?//获取内存中当前文件输入流????
?InputStream in = new FileInputStream(file);
?try {
??int num = 0;
??while ((num = in.read(buffer)) > 0) {
???fos.write(buffer, 0, num);
??}
?} catch (Exception e) {
??e.printStackTrace(System.err);
?} finally {
??in.close();
??fos.close();
?}
?//发送给KE????
?out
???.println("<html><head><title>Insert Image</title><meta http-equiv='content-type' content='text/html; charset=gbk'/></head><body>");
?out.println("<script type='text/javascript'>");
?out.println("parent.parent.KE.plugin['image'].insert('"
???+ wrapper.getParameter("id") + "','" + newFileName + "','"
???+ wrapper.getParameter("imgTitle") + "','"
???+ wrapper.getParameter("imgWidth") + "','"
???+ wrapper.getParameter("imgHeight") + "','"
???+ wrapper.getParameter("imgBorder") + "','"
???+ wrapper.getParameter("align") + "');</script>");
?out.println("</body></html>");
