显示已记录的用户数据Java
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，该界面显示已登录用户的地籍数据。我想知道我该怎么做？
是这样吗？ （我创建了一个单独的接口类来查询数据库）我实例化了该接口，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;
}

答案 0 :(得分：1)
您的代码中没有错误，只是您错过了在行ip.setVisible(true);下添加ip.txtExibirEmailPerfil.setText(rs.getString("Email"));来显示Interface_Perfil的错误。
下面是我的工作代码
首页
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
}
});
UserAPI
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;
}
