我通常使用这种技术:

File folderLocation = new File("/blah/blah/mysystem/myfolder"); 

    if (folderLocation.exists()) { 
     if (!folderLocation .isDirectory()) { 
      throw new IOException("File-system item with path [" + folderLocation.getAbsolutePath() + "] exists but is not a folder."); 
     }     
    } else { 
     if (!folderLocation.mkdirs()) { 
      throw new IOException("Could not create folder with path : " + folderLocation.getAbsolutePath()); 
     } 
    } 

    // we are guaranteed that the folder exists here
