Java 中 更改文件路径

java 中更改文件路径可以用file.renameTo 方法

public static void moveDataFile2Reject() throws Exception {try { //String dataFilePath = PropertyUtil.getString(PropertyUtil.INPUT_FILE_PATH_KEY);//String rejectFilePath = PropertyUtil.getString(PropertyUtil.REJECT_FILE__PATH_KEY);String dataFilePath = "D:\\a\b";String rejectFilePath = "D:\\a\reject";File file = new File(dataFilePath);File[] files = file.listFiles();for (File f : files) {if(f.isFile()){f.renameTo(new File(rejectFilePath + f.getName()));} }} catch (Exception e) {logger.error("moveInFile2Reject Failed" , e);}}

 

//java api:

Renames the file denoted by this abstract pathname.

Many aspects of the behavior of this method are inherently platform-dependent: The rename operation might not be able to move a file from one filesystem to another, it might not be atomic, and it might not succeed if a file with the destination abstract pathname already exists. The return value should always be checked to make sure that the rename operation was successful.
