我正在尝试检查登录，但不断收到错误。将mysql连接到javafx应用程序
首先检查功能在不同的类：
public class JavaDBConnection{
public boolean auth(String user, String pass) throws SQLException, ClassNotFoundException{
boolean login;
Connection conn =null;
String dbuser = "root";
String dbpassw = "0557724289";
String databasename = "java_cinemaTickets";
String url = "jdbc:[email protected]:3306/java_cinemaTickets";
Class.forName("com.mysql.jdbc.Driver");
conn = DriverManager.getConnection(url,dbuser,dbpassw);
Statement st = conn.createStatement();
PreparedStatement ps = conn.prepareStatement("SELECT `customer_name`, `customer_password` FROM `customer` WHERE `customer_name` = ? AND `customer_password` = ?");
ps.setString(1, user);
ps.setString(2, pass);
ResultSet result = ps.executeQuery();
if(result.next()){
login = true;
}
else{login = false;}
return login;
}
}
然后在其他类：
public class Java_CinemaTicket extends Application {
JavaDBConnection db = new JavaDBConnection();
public void start(Stage primaryStage) throws FileNotFoundException {
// Login Stage Start
VBox login_pane = new VBox(15);
login_pane.setPadding(new Insets(10,10,10,10));
GridPane login_gridPane = new GridPane();
login_gridPane.setHgap(5);
login_gridPane.setVgap(5);
TextField user_name = new TextField();
PasswordField user_password = new PasswordField();
后来类：
login_button.setOnAction(e->{
String userNamestring = user_name.getText();
String userstring = user_password.getText();
if(customer_radioButton.isSelected()==true){
try {
if(db.auth(userNamestring, userstring) == true){
primaryStage.setTitle("Customer GUI");
primaryStage.setScene(customer);
primaryStage.show();
}} catch (SQLException ex) {
Logger.getLogger(Java_CinemaTicket.class.getName()).log(Level.SEVERE, null, ex);
} catch (ClassNotFoundException ex) {
Logger.getLogger(Java_CinemaTicket.class.getName()).log(Level.SEVERE, null, ex);
}
}
}
和输出错误：
