struts2:配置<constant name="struts.multipart.saveDir" value="d:\tmp"/>

JSP:代码：<input type="file" id="upFile" name="upFile">
<input type="button" value="上传" onclick="uploadFile()"/>
<input id="imgPath" type="hidden" name="photoPath"/>
JS代码：function uploadFile(){
//调用插件的上传方法

return false;
}else{
$.ajaxFileUpload({
url:"uploadImg.action",
fileElementId:"upFile",
secureuri:false,

action代码：private File upFile; //文件
private String upFileFileName; //文件名
private String upFileContentType;
private String filePath; //文件路径
get set..
public void uploadImg(){
String path = ServletActionContext.getServletContext().getRealPath("/upload");

String fileName = java.util.UUID.randomUUID().toString(); // 采用时间+UUID的方式随即命名
System.out.println(upFileFileName);

int length = 0;
while ((length = inputStream.read(buf)) != -1) {

inputStream.close();
outputStream.flush();
//文件保存的完整路径 比如：D:\tomcat6\webapps\eserver\\upload\a0be14a1-f99e-4239-b54c-b37c3083134a.png
filePath = path+"\\"+name;
}
} catch (Exception e) {
e.printStackTrace();
}
}
错误;上传不成功。输出这句话[ INFO] (CommonsLogger.java:31) - Removing file upFile d:\tmp\upload__595ab118_14b050e3e0f__8000_00000000.tmp，搞不清楚啥原因啊来个大神指点下吧.

貌似是临时删除文件有问题么？ 我来学习学习
