Java Apache JSP Servlet PHP

最近公司要换图文混排，发现kindEditor非常不错，下载http://www.kindsoft.net/下来用了用，发现上传功能只有php的，郁闷。。。
没办法自己写一个。。。

upload.jsp

	String id = "";
	String url = "";
	String imgTitle = "";
	String imgWidth = "";
	String imgHeight = "";
	String imgBorder = "";

	// **************************************
	// 初始化上传工厂对象

			.getServletContext().getRealPath("/")));
	// 创建上传对象
	ServletFileUpload upload = new ServletFileUpload(factory);
	upload.setFileSizeMax(1024 * 1024 * 20);
	List<FileItem> items = null;

	}
	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('" + id

			+ "');</script>");
	out.println("</body></html>");
%>

代码完了，发在跟他的PHP文件一个目录就可以了
再把image.html文件的action一改，OK

！
拿到Struts2应用中，

问题又来了。。。
没办法一句一句的debug！
问题找到了，原来S2为简化上传功能，把所有的enctype="multipart/form-data"表单做了wrapper最后把HttpServletResquest封装成
org.apache.struts2.dispatcher.multipart.MultiPartRequestWrapper
怪不得我的
ServletFileUpload.parseRequest(request)不行！！！
还我原来的request

！！！
不过查看它的API 原来人家已经为咱做好了呵呵，比原来的方便许多。
继续代码：

struts2Upload.jsp

<%
	//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>");
%>

这回好了，问题解决了，大家多多提意见，那个后台图片管理用不到，就没写

如果你用的是Struts2使用struts2Upload.jsp
若果你没用Struts2使用upload.jsp

楼主，用你的struts2Upload.jsp上传本地图片时，还是提示“服务器发生故障”~~请问能否解释一下~~
如果把
<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>

里的/*改成其他的，又会抛出异常~~

在我这里没有问题 ,把你的异常信息发一下.
你给我web.xml内容没有用 . 不过你可以尝试使用火狐的filebug去分析一下看看你的请求数据是什么。
也可以在struts2Upload.jsp里写日志查看每行运行结果。

4 楼 cnwong 2010-10-21

very very good！LZ解决了
ServletFileUpload upload = new ServletFileUpload(factory);
List items = upload.parseRequest(request);
items为空的问题。敬礼！

3 楼 ztianlong 2010-05-03

嗯呵呵

2 楼 hot66hot 2010-04-19

ztianlong 写道

out.println("parent.parent.KE.plugin['image'].insert('"

怎么是两个 parent 啊
应该是一个吧我试了

谢谢分享~! jsp版和struts2 中都用到你的东西了嘿嘿

kindeditor3.4是两个parent。
kindeditor3.3是一个parent。
根据它的PHP_DEMO实现的.
呵呵,对你有用就好。
