java.nio.file.FileSystemException:进程无法访问该文件,因为它正被另一个进程使用 [英] java.nio.file.FileSystemException: The process cannot access the file because it is being used by another process
问题描述
我正在编写一个程序,在第一次执行时将它们自己复制到特定文件夹,在 linux 或 windows 中工作.
在 linux 中它工作得很好,但是当我尝试在 windows 上做同样的事情时,我收到以下错误:
I'm writing a program that copy themselve at first execution to a specific folder, working in linux or windows.
In linux it works perfectly but when I try to do the same on windows i get the following error:
java.nio.file.FileSystemException: 进程无法访问该文件,因为它正被另一个进程使用(在 sun.nio.fs.WindowsException 中)
java.nio.file.FileSystemException: The process cannot access the file because it is being used by another process (in sun.nio.fs.WindowsException)
那么,另一个进程就是程序本身,我应该用什么来跳过这个错误?
So, the other process is the program itself, what should I use to skip this error?
我的代码行是:
public void installProgram (){
System.out.println("Doing Install...");
File fileToBeInstalled = new File(MyClass.class.getProtectionDomain().getCodeSource().getLocation().toURI().getPath());
try {
Files.move(fileToBeInstalled.toPath(), installPathFile.toPath(), REPLACE_EXISTING);
} catch (IOException ex) {
MainClass.getMainClass(InstallerLinux.class.getName()).log(Level.SEVERE, null, ex);
}
}
谢谢!
推荐答案
好的,我没有找到完美的解决方案,但有些东西......
Ok, I don't found a perfect solution but something...
try {
//Files.move(fileToBeInstalled.toPath(), installPathFile.toPath(), REPLACE_EXISTING);
Files.copy(fileToBeInstalled.toPath(), installPathFile.toPath(), REPLACE_EXISTING);
fileToBeInstalled.delete();
} catch (IOException ex) {
MainClass.getMainClass(InstallerLinux.class.getName()).log(Level.SEVERE, null, ex);
}
此文件正确复制并仅在 linux 执行时正确擦除原始文件.
This copy correctly the file and erases correctly the original only on linux execution.
我认为要做到这一点,我需要使用类加载器调用该类..
I think for do that I need to invoke the class using a class loader..
