Java插入MySQL工作台

Question

I have a mySQL database named Customer that I am trying to insert data from a textfield in a GUI. I ran the code below and in the console it said "Connected Successfully" with no errors. I checked to see if the information had been inserted into the Customer table of my mySQL database and nothing was inserted. Does anyone know why?

         button.setOnAction(e -> {


         Connection dbConnection = null;
            PreparedStatement preparedStatement = null;

         try {


           Customer cust = new Customer();
          dbConnection = Connect();
            String sql="Insert into CIS3270.Customer(firstName,lastName, email,userNAME,Address,Zip,State,SecurityQ,  Password, ConfirmPassword,SSN)VALUES (?,?,?,?,?,?,?,?,?,?,?)"; 
            preparedStatement =  dbConnection.prepareStatement(sql);


            preparedStatement.setString(1,cust.getFirstName()); 
            preparedStatement.setString(2,cust.getLastName()); 
            preparedStatement.setString(3,cust.getEmail()); 
            preparedStatement.setString(4,cust.getUserNAME()); 
            preparedStatement.setString(5,cust.getAddress());
            preparedStatement.setString(6,cust.getZip()); 
            preparedStatement.setString(7,cust.getState());
            preparedStatement.setString(8,cust.getSecurityQuestion());
            preparedStatement.setString(9,cust.getPassWORD()); 
            preparedStatement.setString(10,cust.getConfirmPassword());
            preparedStatement.setString(11,cust.getSSN()); 

            preparedStatement.executeBatch(); 
            preparedStatement.executeUpdate();

            dbConnection.close(); 
            preparedStatement.close(); 



        LoginScreen loginPage = new LoginScreen();

        loginPage.start(primaryStage);

         }
         catch(Exception e1) {
            e1.printStackTrace();
         }
    });

       public static Connection Connect() {
       Connection con = null;
    try {
        Class.forName("com.mysql.jdbc.Driver");
        con = (Connection) DriverManager.getConnection("jdbc:mysql://(ip adress):3306/CIS3270", "root", "password");
    } catch (Exception e) {
        System.out.println("Can not connect");
    }
    if (con != null) {
        System.out.println("Connected Successfully");
    }
    return con;
}

You have no need for a batch insert since you're inserting a single row.

The reason your code doesn't do anything is because you're executing an empty batch. You need to call preparedStatement.addBatch() too. Or just remove that executeBatch() call, as you seem to call executeUpdate() too.
