dbconnect.java

学习 java 做 的一些 小 试验。。。。。。。可以

package com.wczy.common.db;

import java.sql.DriverManager;
import java.sql.SQLException;
import java.sql.Connection;
import java.util.ResourceBundle;

public class DBConnect {

	private static String driver1, url1, user1, password1;
	static {
		ResourceBundle bundle = ResourceBundle
				.getBundle("com.wczy.common.db.db");
		driver1 = bundle.getString("driver");
		url1 = bundle.getString("url");
		user1 = bundle.getString("user");
		password1 = bundle.getString("password");
	}

	public static Connection getConnection() {
		try {
			Class.forName(driver1);
		} catch (ClassNotFoundException e) {
			e.printStackTrace();
		}
		try {
			return (Connection) DriverManager.getConnection(url1, user1,
					password1);
		} catch (SQLException e) {
			e.printStackTrace();
			throw new RuntimeException(e);
		}

	}

	public static Connection closeConnection(Connection con) {
		if (con != null)
			try {
				con.close();
			} catch (SQLException e1) {
				e1.printStackTrace();
			}
		return con;
	}

	public static void main(String[] args) {
		System.out.println(getConnection());
	}
}
