Java程序，通过java.nio.file.FileStore检查支持的属性
以下是我们的文件：
Path p = Paths.get("E:/input.txt");
FileStore file = Files.getFileStore(p);现在，一一检查支持的属性：
FileAttributeView = file.supportsFileAttributeView(FileAttributeView.class) PosixFileAttributeView = file.supportsFileAttributeView(PosixFileAttributeView.class) BasicFileAttributeView = file.supportsFileAttributeView(BasicFileAttributeView.class)
示例
import java.nio.file.FileStore;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.nio.file.attribute.BasicFileAttributeView;
import java.nio.file.attribute.FileAttributeView;
import java.nio.file.attribute.FileOwnerAttributeView;
import java.nio.file.attribute.PosixFileAttributeView;
public class Demo {
public static void main(String[] args) throws Exception {
Path p = Paths.get("E:/input.txt");
FileStore file = Files.getFileStore(p);
System.out.println("FileAttributeView = " + file.supportsFileAttributeView(FileAttributeView.class));
System.out.println("PosixFileAttributeView = "+ file.supportsFileAttributeView(PosixFileAttributeView.class));
System.out.println("BasicFileAttributeView = "+ file.supportsFileAttributeView(BasicFileAttributeView.class));
System.out.println("FileOwnerAttributeView supported = "+ file.supportsFileAttributeView(FileOwnerAttributeView.class));
}
}输出结果
FileAttributeView = false PosixFileAttributeView = false BasicFileAttributeView = true FileOwnerAttributeView supported = true
