如何將File.setReadable映射到NIO路徑操作

Question

什麼是「獨立於平臺完成File.setReadable」的「新」方法？是PosixFilePermissions還是別的？

Answer 1

您應該使用方法等Files類setPosixFilePermissions：

Set<PosixFilePermission> permissions = new HashSet<PosixFilePermission>(); 
permissions.add(PosixFilePermission.OWNER_READ); 
permissions.add(PosixFilePermission.OWNER_WRITE); 
permissions.add(PosixFilePermission.OWNER_EXECUTE); 
permissions.add(PosixFilePermission.GROUP_READ); 
permissions.add(PosixFilePermission.GROUP_WRITE); 
permissions.add(PosixFilePermission.GROUP_EXECUTE); 
permissions.add(PosixFilePermission.OTHERS_READ); 
permissions.add(PosixFilePermission.OTHERS_WRITE); 
permissions.add(PosixFilePermission.OTHERS_EXECUTE); 
Files.setPosixFilePermissions(Paths.get("file.ext"), permissions);
