	package com.jint.db;
	
	import java.sql.Connection;
	import java.sql.DriverManager;
	import java.sql.SQLException;
	
	public class DBUtil {
	
	 private static final String URL = "jdbc:mysql://127.0.0.1:3306/test";
	 private static final String USER = "root";
	 private static final String PASSWORD = "";
	
	 private static Connection connection = null;
	
	 static {
	 try {
	 // 1.加载驱动
	 Class.forName("com.mysql.jdbc.Driver");
	 // 2.获得数据库连接
	 connection = DriverManager.getConnection(URL, USER, PASSWORD);
	 } catch (ClassNotFoundException e) {
	 // TODO Auto-generated catch block
	 e.printStackTrace();
	 } catch (SQLException e) {
	 // TODO Auto-generated catch block
	 e.printStackTrace();
	 }
	 }
	
	 public static Connection getConnection(){
	 return connection;
	 }
	
	 /*public static void main(String[] args) throws Exception {
	 Statement statement = connection.createStatement();
	 ResultSet rs = statement.executeQuery("select user_name,age from goddess");
	 while (rs.next()) {
	 System.out.println(rs.getString("user_name") + "," + rs.getInt("age"));
	 }
	 }*/
	}
