我在我的应用程序中编写了 AJAX 文件上传功能。从我的笔记本电脑上运行它时效果很好。当我使用相同的应用程序尝试完全相同的文件,但部署在 jBoss 服务器上时,我得到以下异常:
2013-02-18 11:30:02,796 ERROR [STDERR] java.io.FileNotFoundException: C:\Users\MyUser\Desktop\TestFile.pdf (The system cannot find the file specified).
获取文件数据方法:
private byte[] getFileData(File file) {
FileInputStream fileInputStream = null;
byte[] bytFileData = null;
try {
fileInputStream = new FileInputStream(file);
} catch (FileNotFoundException e1) {
e1.printStackTrace();
}
if (fileInputStream != null) {
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
byte[] bytBuffer = new byte[1024];
try {
for (int readNum; (readNum = fileInputStream.read(bytBuffer)) != -1;) {
byteArrayOutputStream.write(bytBuffer, 0, readNum);
}
} catch (IOException e) {
e.printStackTrace();
}
bytFileData = byteArrayOutputStream.toByteArray();
}
return bytFileData;
}
在变量中获取文件内容(通过上述方法):
byte[] bytFileData = this.getFileData(file);
制作文件:
private boolean makeFile(File folderToMake, File fileToMake, byte[] bytFileData) {
Boolean booSuccess = false;
FileOutputStream fileOutputStream = null;
try {
if (!folderToMake.exists()) {
folderToMake.mkdirs();
}
if (!fileToMake.exists()) {
if (fileToMake.createNewFile() == true) {
booSuccess = true;
fileOutputStream = new FileOutputStream(fileToMake);
fileOutputStream.write(bytFileData);
fileOutputStream.flush();
fileOutputStream.close();
}
}
} catch (Exception e) {
e.printStackTrace();
booSuccess = false;
}
return booSuccess;
}
任何想法?
谢谢
