java 访问数据库 java.sql.SQLException: Column not found的问题

用java写一个很简单的数据库访问程序，但是如果表跟字段中出现中文，会出现这样的错误：java.sql.SQLException: Column not found

解决方法之一是在连接是指定gb2312

Properties prop = new Properties();
prop.put("charSet", "gb2312");
prop.put("username", username);
prop.put("password", password);
connect=DriverManager.getConnection(url,prop);

完整的程序：

package my;
import java.sql.*;
import java.util.Properties;

import javax.swing.JOptionPane;
public class DataBase {
	static Connection connect;
	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		if((connect=connectByJdbcOdbc("jdbc:odbc:AccessDB","",""))!=null){
			JOptionPane.showMessageDialog(null, "连接数据库成功");
			try{
				readRecord();
				connect.close();
				connect=null;
			}catch(SQLException e){
				System.out.println("关闭数据时异常");
			}
		}else{
			JOptionPane.showMessageDialog(null, "连接数据库失败");
		}
		

	}
	static void readRecord(){
		Statement staSql;
		ResultSet rs;
		//读数据库
		try{
			staSql=connect.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY);
			rs=staSql.executeQuery("SELECT * FROM 表1");
			rs.first();
			System.out.println("staSql OK");
			System.out.print(rs.getString("学号")+"	");
			System.out.println(rs.getString("姓名"));
		}catch(Exception e){
			System.out.println("read error");
			System.out.println(e);
		}		
	}
	
	public static Connection connectByJdbcOdbc(String url,String username,String password){
		Connection connect;
		Properties prop = new Properties();
		try{
			Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
			
			prop.put("charSet", "gb2312");
			prop.put("username", username);
			prop.put("password", password);
			
		}catch(Exception e){
			e.printStackTrace();
			return null;
		}
		
		try{
			connect=DriverManager.getConnection(url,prop);
		}catch(SQLException e){
			e.printStackTrace();
			return null;
		}
		return connect;
	}
}
