private void createFile(String newLine){
        try {
            //建立输入流
            File logFile = new File(filePath);
            boolean exits = logFile.createNewFile();
            FileWriter fWriter = new FileWriter(logFile, true);
            PrintWriter out = new PrintWriter(fWriter, true); ;
            out.println(newLine);
            out.close();
            fWriter.close();
