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。。。

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:
引用

org.apache.struts2.dispatcher.multipart.MultiPartRequestWrapper,

//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>");

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
