Java检查文件是否已经打开

使用Apache Commons IO库…

boolean isFileUnlocked = false;try {    org.apache.commons.io.FileUtils.touch(yourFile);    isFileUnlocked = true;} catch (IOException e) {    isFileUnlocked = false;}if(isFileUnlocked){    // Do stuff you need to do with a file that is NOT locked.} else {    // Do stuff you need to do with a file that IS locked}
