java - 显示记录的用户数据java

转载作者：行者123 更新时间：2023-12-02 10:45:53

我已经创建了一个用户登录的界面，现在我想创建另一个界面，在其中显示登录用户的地籍数据。我想知道我该怎么做？

是这样的吗？ (我创建了一个单独的接口(interface)类来查询数据库)我实例化了接口(interface)并让textField发送ResultSet结果

  public boolean checkLogin(String nick, String senha) {

    Connection con = JBancoDeDados.getConnection();
    PreparedStatement stmt = null;
    ResultSet rs = null;

    boolean check = false;

    try {

        stmt = con.prepareStatement("SELECT * FROM usuario WHERE Nick = ? and Senha = ?");
        stmt.setString(1, nick);
        stmt.setString(2, senha);
        rs = stmt.executeQuery();

        if (rs.next()) {
            check = true;
            Interface_Perfil ip = new Interface_Perfil();
            ip.txtExibirNomePerfil.setText(rs.getString("Nome"));
            ip.txtExibirNickPerfil.setText(rs.getString("Nick"));
            ip.txtExibirSenha.setText("Senha");
            ip.txtExibirEmailPerfil.setText(rs.getString("Email"));

        }

    } catch (SQLException ex) {
        Logger.getLogger(UsuarioDAO.class.getName()).log(Level.SEVERE, null, ex);
    } finally {
        JBancoDeDados.closeConnection(con, stmt, rs);
    }   
    return check;   
    }

最佳答案

您的代码中没有错误，只是您错过了在 ip.txtExibirEmailPerfil.setText(rs.getString("Email")) 行下方添加 ip.setVisible(true); ; 显示 Interface_Perfil。

下面是我的工作代码

主页

 login.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                String Name = name.getText();
                String Pass = new String(pass.getPassword());

                UserAPI user = new UserAPI();
                user.checklogin(Name, Pass);       
            }

            private void setVisible(boolean b) {
                // TODO Auto-generated method stub

            }
        });

用户API

public boolean checklogin(String name, String Pass) throws Exception {
        boolean check = false;

        String sql = "SELECT * FROM admin WHERE name =? and password= ?";
        DatabaseConnection db = new DatabaseConnection();
        Connection conn = db.getConnection();
        PreparedStatement ps = conn.prepareStatement(sql);
        ps.setString(1, name);
        ps.setString(2, Pass);

        ResultSet rs = ps.executeQuery();
        if (rs.next()) {
            check = true;
            Interface_Perfil ip = new Interface_Perfil();
            System.out.println("dddd");
            ip.txtExibirNomePerfil.setText(rs.getString("name"));
            ip.txtExibirNickPerfil.setText(rs.getString("password"));
            ip.txtExibirSenha.setText("Senha");
            ip.txtExibirEmailPerfil.setText("email@hotmail.com");
            ip.setVisible(true);
        }
        ps.close();
        rs.close();
        conn.close();
        return check;
    }
