我想在mysql的jtable中显示记录

Question

我想在mysql的jtable中显示记录，我的表包含四行。 用户名varchar，登录时间戳，注销时间戳，状态字符。

   public class Secondpage extends javax.swing.JFrame {
   java.sql.Connection conn=null;
   java.sql.PreparedStatement pst = null;
   ResultSet rs = null;
   public Secondpage() throws SQLException{
   initComponents();
   conn =DriverManager.getConnection("jdbc:mysql://localhost:3306/login?" + 
   "user=root&password=");
   update_table();
   }
   private void update_table(){

   try{
   String sql = "Select * from userlog";
   pst = conn.prepareStatement(sql);
   rs =  pst.executeQuery();
   table.setModel(DbUtils.resultSetToTableModel(rs));
   }

运行程序后，我有这样的错误。

java.sql.SQLException:java.sql.Timestamp

检查您的连接URL。

conn=DriverManager.getConnection( "jdbc:mysql://localhost:3306/yourdatabasename","username","p‌​assword");
