java - java向mysql插入数据的问题

Question

我创建了类来处理数据库实现。我构建了 javafx GUI。其中一个按钮应该将数据存储到数据库中。据了解，我使用相同的数据库登录，因此问题不在于数据库连接。

数据库实现:

        Connection conn =null;
        String dbuser = "root";
        String dbpassw = "0557724289";
        String databasename = "java_cinemaTickets";
        String url = "jdbc:mysql://127.0.0.1:3306/java_cinemaTickets";
        String driver = "com.mysql.jdbc.Driver";
        PreparedStatement ps;

public void addMovie_insetIntoDB(String title,String description,String cinema,String time,int threator,String movie_uniqeID,String image) throws ClassNotFoundException, SQLException{

     Class.forName(driver);
        conn = DriverManager.getConnection(url,dbuser,dbpassw);
        Statement st = conn.createStatement();

        ps = conn.prepareStatement("insert into movie(movie_name,description,time,threator,mviUniqeID,movie_poster,catgory,age)"+"values(?,?,?,?,?,?,?,?,?)");

       ps.setString(1, title);
       ps.setString(2, description);
       ps.setString(3, cinema);
       ps.setString(4, time);
       ps.setInt(5, threator);
       ps.setString(6, movie_uniqeID);
       ps.setString(7, image);



       ps.executeQuery();

       conn.close();

}

然后在另一个类中:

String movieName_String = movieNameToAdd_textField.getText();
    String movieDescription_String = MovieDescriptionToAdd_textArea.getText();
    String moviePoster_string= "rr";//moviePoster_textField.getText();
    String cinemaLocation_string = cinemaToAdd_comboBox.getSelectionModel().getSelectedItem().toString();
    String movieTime_string = timeToAdd_comboBox.getSelectionModel().getSelectedItem().toString();
    int  movieThretor_integer = Integer.parseInt(threatorToAdd_comboBox.getSelectionModel().getSelectedItem().toString());
    String movieUniQID="jj";



    adminAddMovie_button.setOnAction(e->{


        try {
            db.addMovie_insetIntoDB(movieName_String,movieDescription_String,cinemaLocation_string,movieTime_string,movieThretor_integer,movieUniQID,moviePoster_string);
        } catch (ClassNotFoundException ex) {
            Logger.getLogger(Java_CinemaTicket.class.getName()).log(Level.SEVERE, null, ex);
        } catch (SQLException ex) {
            Logger.getLogger(Java_CinemaTicket.class.getName()).log(Level.SEVERE, null, ex);
        }

    primaryStage.setTitle("Admin GUI");
    primaryStage.setScene(admin_Scene);
    primaryStage.show();

    });

按下按钮将数据保存到数据库后收到错误

Answer 1

据我所知，您需要使用 executeUpdate() 进行 DML 操作(插入/更新/删除)，而不是 executeQuery()。

仔细查看并阅读异常消息，它在这里说的是完全相同的事情java.sql.SQLException:无法使用executeQuery()发出数据操作语句。
