我正在尝试使用 Jtable 在 java 中显示数据库中的数据，是的，我已经实现了，但现在冲突是他们显示在一个列中的姓氏和名称，但我希望它们显示在不同的列中。下面是我的代码请帮助..
import java.awt.Dimension;
import java.io.PrintWriter;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.table.*;
import com.mysql.jdbc.Connection;
import com.mysql.jdbc.Statement;
public class ju {
private static Object request;
static JTable mysTable;
//constructor method
public static void main (String args []){
String [] columnNames = {"Name","Lastname","Id","Style"};
mysTable = new JTable(4,4);
mysTable.setBounds(20,10,300,300);
JFrame frame = new JFrame("King Musa Saloon Software");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setLayout(null);
frame.setSize(500,500);
frame.setResizable(false);
frame.setVisible(true);
frame.add(mysTable);
//frame.add(mysTable);
try {
Class.forName("com.mysql.jdbc.Driver");
System.out.println("Driver loading success!");
String url = "jdbc:mysql://localhost:3306/saloon";
String name = "root";
String password = "";
try {
java.sql.Connection con = DriverManager.getConnection(url, name, password);
System.out.println("Connected.");
// pull data from the database
java.sql.Statement stmts = null;
String query = "select userid, username, name from saloonuser ";
stmts = con.createStatement();
ResultSet rs = stmts.executeQuery(query);
int li_row = 0;
while(rs.next()){
mysTable.setValueAt(rs.getString("username"),li_row,0);
mysTable.setValueAt(rs.getString("name"),li_row,0);
int userid = rs.getInt("userid");
String username = rs.getString("username");
String name1 = rs.getString("name");
System.out.println(name1);
li_row++;
}
} catch (SQLException e) {
e.printStackTrace();
}
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
}
}
