用java 代码，动态修改，拼接sql、执行

1、用java 代码，动态修改，拼接sql、执行


waybillNo.sql 文件中内容

425787921414,
425404118389,
425067648257,


2、链接数据库


package test;

import java.sql.DriverManager;
import java.sql.SQLException;

import com.mysql.jdbc.Connection;
import com.mysql.jdbc.PreparedStatement;

public class DBHelper {
    public static final String url = "jdbc:mysql://172.0.0.0/test";  
    public static final String name = "com.mysql.jdbc.Driver";  
    public static final String user = "root";  
    public static final String password = "test";  
  
    public Connection conn = null;  
    public PreparedStatement pst = null;  
  
    public DBHelper(String sql) {  
        try {  
            Class.forName(name);//指定连接类型  
            conn = (Connection) DriverManager.getConnection(url,user,password);//获取连接  
            pst = (PreparedStatement) conn.prepareStatement(sql);//准备执行语句  
        } catch (Exception e) {  
            e.printStackTrace();  
        }  
    }  
  
    public void close() {  
        try {  
            this.conn.close();  
            this.pst.close();  
        } catch (SQLException e) {  
            e.printStackTrace();  
        }  
    } 
}
