获取数据以填充JTable netbeans

Question

我已成功连接到MySQL数据库，并且可以在命令中打印数据，但我想将它们放入JTable中。我知道以下是不允许的，但我怎么能这样做;

jTable1.setValueAt(connect.rs.getString("name"), row, 0); 
jTable1.setValueAt(connect.rs.getString("price"), row, 1); 

正确的方法是;

jTable1.setValueAt(connect.rs.getString(1), row, 0); 
jTable1.setValueAt(connect.rs.getString(2), row, 1); 

但我不知道1和2代表什么。

真的，我只想获取所有数据，并使用MySQL的名称和价格变量填充JTable。

这是我的DBConnect类;

import java.sql.*; 


public class DBConnect { 

private Connection con; 
private Statement st; 
public ResultSet rs; 
public String name; 
public String ph; 
public DBConnect(){ 
    try{ 
     Class.forName("com.mysql.jdbc.Driver"); 

     con = DriverManager.getConnection("jdbc:mysql://buiud.com:3306/buiud458_androidhive","XXX","XXX"); 

     st = con.createStatement(); 

    } 
    catch(Exception ex){ 
     System.out.println("Err: "+ex); 
    } 
} 

public void getData(){ 
    try{ 
     String query = "select * from products"; 
     rs = st.executeQuery(query); 
     System.out.println("Records from database"); 
     while(rs.next()){ 
      name = rs.getString("name"); 
      ph = rs.getString("price"); 
      System.out.println("Name: "+name+" "+"Price: "+ph); 
     } 
    }catch(Exception ex){ 
     System.out.println("ERR: "+ex); 
    } 
} 
} 

Answer 1

//全局声明

private Vector<Vector<String>> data; //used for data from database 
private Vector<String> header; //used to store data header 

//显示信息，以JTable中

data = get(); 

//create header for the table 
header = new Vector<String>(); 
header.add("Column1"); 
header.add("Column2"); 
... 
model=new DefaultTableModel(data,header); 
table = new JTable(model); 

这将帮助你从数据库中获取数据

get(){ 
Vector<Vector<String>> doublevector = new Vector<Vector<String>>(); 

Connection conn = dbConnection();//Your Database connection code 
PreparedStatement pre1 = conn.prepareStatement("select * from Table"); 

ResultSet rs1 = pre1.executeQuery(); 
while(rs1.next()) 
{ 
Vector<String> singlevector = new Vector<String>(); 
singlevector.add(rs1.getString(1)); 
singlevector.add(rs1.getString(2)); 
.... 
doublevector.add(singlevector); 

} 

return doublevector; 
}
