struts2 文件上传问题 临时文件夹的 探讨
我用的是eclipse j2ee web 开发版！
此问题纠结了半天了、、、据说是路径的问题我用\ /都试了，好像没处在这上面、、、不知其什么原因、、、各位帮帮看看



struts.xml

  <constant name="struts.multipart.saveDir" value="\tmp"></constant>
  <constant name="struts.mutilpart.maxSize" value="1024000"></constant>  
  <package name="upload" extends = "struts-default">  
  <action name="upload" class = "org.leno.struts2.action.UploadAction">
  <interceptor-ref name="fileUpload">
  <param name="maxinmumSize">1024000</param>
  <param name="allowedTypes">text/plain</param>
  </interceptor-ref>
  <interceptor-ref name="defaultStack" ></interceptor-ref>
 
  <result name="success">/success.jsp</result>
  <result name= "input">/singleUpload.jsp</result>
 
  </action> 
 </package>



UploadAction.java 为：


  private File upload ;
private String uploadFileName;
private String uploadContentType;
  、、、、、、
  String newroot = ServletActionContext.getServletContext().getRealPath("/upload");
System.out.println(newroot);

File dir = new File(newroot,getUploadFileName());
FileInputStream input = new FileInputStream(getUpload());
FileOutputStream output = new FileOutputStream(dir);

byte[] buf = new byte[100];
int len = 100;
while((len = input.read())>=0)
{
output.write(buf, 0, len);
}
input.close();
output.close();





问题是：

控制台信息为：
