JFileChooser - open in current directory
提问by CodeGuy
I have a simple JFileChooser set up in the following manner
我按以下方式设置了一个简单的 JFileChooser
JFileChooser chooser = new JFileChooser();
chooser.setCurrentDirectory(new File("."));
chooser.setFileSelectionMode(JFileChooser.FILES_AND_DIRECTORIES);
chooser.setFileFilter(new FileFilter() {
...
});
int v = chooser.showOpenDialog(this);
if (v == JFileChooser.APPROVE_OPTION) {
File file = chooser.getSelectedFile();
System.out.println(file.getAbsolutePath());
}
As you can see, this FileChooser starts out in the current directory, which in my Netbeans project, is the root of the project folder. Here's the problem: When I select a file and it prints out the absolute path, it includes the "."in the path. For instance, the output I get is:
如您所见，这个 FileChooser 从当前目录开始，在我的 Netbeans 项目中，它是项目文件夹的根目录。问题是：当我选择一个文件并打印出绝对路径时，它会"."在路径中包含。例如，我得到的输出是：
/Users/MyName/Folder1/Folder2/./Temp.xls
Of course, this is weird, especially since I'm displaying this to the user. Now, I could be hacky and do some fun post substring processing stuff to get rid of that "/./"portion. But...is there a non-lazy programmer way to fix this problem? Thanks in advance!
当然，这很奇怪，尤其是因为我要向用户显示它。现在，我可以做一些有趣的后期子字符串处理来摆脱那"/./"部分。但是......有没有一种非懒惰的程序员方法来解决这个问题？提前致谢！

Use the system property "user.dir" as follows:
使用系统属性“user.dir”如下：
File workingDirectory = new File(System.getProperty("user.dir"));
chooser.setCurrentDirectory(workingDirectory);
