多次使用输入流

Question

for (File fileEntry : dir.listFiles()) {
    String strXMLFilename = null;
    strXMLFilename = fileEntry.getName();
    InputStream input = new FileInputStream(strXMLFilename);
    PostMethod post = new PostMethod();
    post.setRequestBody(input);
    .....
    .....
    .....
}

when ever my for loop runs, InputStream input = new FileInputStream(strXMLFilename); this line works fine. But, when the second time it is entering in to for block the re is a problem with this line. I hope the input stream is not reading the file properly. i tried by closing the input stream, even though it is not working.

如果您想多次阅读它，则应该在读取BufferedInputStream之后使用reset方法，或者使用我认为更合适的byte []。
