struts2.0 文件上传问题

[liujun_1028]

我的代码

public String execute() throws Exception
{
for (int i = 0; i < file.size(); ++i)
{
InputStream is = new FileInputStream(file.get(i));

String root = ServletActionContext.getRequest().getRealPath("/upload");

File destFile = new File(root, this.getFileFileName().get(i));

OutputStream os = new FileOutputStream(destFile);

byte[] buffer = new byte[400];

int length = 0;

while ((length = is.read(buffer)) > 0)
{
os.write(buffer, 0, length);
}

is.close();

os.close();
}

return SUCCESS;

}
问题是 我提交上传后 并没有 在 “upload”文件夹下出现我上传的文件？谁能帮我解惑？（控制台未出现任何异常）

if (file.getSize() != 0) {
				InputStream stream = null;
				stream = file.getInputStream();
				OutputStream bos = null;
				bos = new FileOutputStream(outPutPath);
				int bytesRead = 0;
				byte[] buffer = new byte[8192];
				while ((bytesRead = stream.read(buffer, 0, 8192)) != -1) {
					bos.write(buffer, 0, bytesRead);
				}
				bos.close();
				stream.close();
			}

这个是我的Struts2 文件上传代码，你自己对照下试试。

1.引用commons-io.x.x.jar

2.java代码：

String path = request.getRealPath("/upload");
File saveFile = new File(path, fileFileName);
FileUtils.copyFile(file, saveFile);
