一、通过下面方式
BasicFileAttributes attr = null;
try {
Path path = file.toPath();
attr = Files.readAttributes(path, BasicFileAttributes.class);
} catch (IOException e) {
e.printStackTrace();
}
// 创建时间
Instant instant = attr.creationTime().toInstant();
二、完整代码
public class ReadFileTimeUtils {
public static String file = "/Users/zhangboqing/Downloads/testfileclassify copy/Archives/2020-21-07/11.dmg";
public static void main(String[] args) throws IOException {
File f = new File(file);
System.out.println(getCreationTime(f));
// Path file = f.toPath();
// BasicFileAttributes attr = Files.readAttributes(file, BasicFileAttributes.class);
// System.out.println("creationTime: " + attr.creationTime());
// System.out.println("lastAccessTime: " + attr.lastAccessTime());
// System.out.println("lastModifiedTime: " + attr.lastModifiedTime());
}
public static String getCreationTime(File file) {
if (file == null) {
return null;
}
BasicFileAttributes attr = null;
try {
Path path = file.toPath();
attr = Files.readAttributes(path, BasicFileAttributes.class);
} catch (IOException e) {
e.printStackTrace();
}
// 创建时间
Instant instant = attr.creationTime().toInstant();
// 更新时间
// Instant instant = attr.lastModifiedTime().toInstant();
// 上次访问时间
// Instant instant = attr.lastAccessTime().toInstant();
String format = DateTimeFormatter.ofPattern("yyyy-MM-dd").withZone(ZoneId.systemDefault()).format(instant);
return format;
}
}
