从CSV读取数据时，它会跳过第二行。我有两个CSV文件，一个用于用户，一个用于属性-密钥ID是user。

    String userName;
    static String breakLine = "\n--------------------\n";
        /**
        * Method to create a new user in a CSV File

   static void writeToCsvFile(String sFileName, User user)
   {
    try
    {
        FileWriter writer = new FileWriter(sFileName, true);


        writer.append(user.displayUserName()); // get username from userinput
        writer.append(","); // tabs to next record

        writer.append(user.getPassword()); //gets password from userinput
        writer.append(","); //tabs to next record
        writer.append("\n");

        writer.flush();
        writer.close();
        System.out.print("\nUser Successfully Created\n");
    }
    catch(IOException e)
    {
         e.printStackTrace();
    }

   }

我与以下用户一起运行

Chris,password
Michelle,password
Zach,password
etc (on seperate lines, seperated by appending \n at the end of the input stage)

每个奇数编号都在工作，并且检测到用户已登录，而第二个奇数编号正在跳过。我阅读了一下，但我不认为我有.nextLine（）正在像此链接中那样跳过，但是我只在星期五开始使用CSV和BufferedReader！
