java+swing+mysql項目管理系統附帶系統運行指導視頻

今天我們演示一個java swing組件開發的簡單項目管理系統。

源碼獲取地址【當牛作碼-最專業的源代碼分享網站】：http://www.xiaoniucr.com/project/view/14.html

項目介紹：

本系統主要使用eclipse+jdk1.7開發，使用swing圖形化組件，在配合mysql數據庫，實現數據的增刪改查。

核心代碼：

1.數據庫鏈接代碼

package com.gzskco.util;

import java.sql.Connection;
import java.sql.DriverManager;

public class DbUtil {

	private String dbUrl="jdbc:mysql://localhost:3306/db_company";
	private String dbUserName="root";
	private String dbPassword="root";
	private String jdbcName="com.mysql.jdbc.Driver";
	
	/**
	 * 獲取數據庫連接
	 * @return
	 * @throws Exception
	 */
	public Connection getCon() throws Exception{
		Class.forName(jdbcName);
		Connection con=DriverManager.getConnection(dbUrl,dbUserName,dbPassword);
		return con;
	}
	
	/**
	 * 關閉數據庫連接
	 * @param con
	 * @throws Exception
	 */
	public void closeCon(Connection con) throws Exception{
		if(con!=null){
			con.close();
		}
	}
	
	public static void main(String[] args) {
		DbUtil dbUtil=new DbUtil();
		try {
			dbUtil.getCon();
			System.out.println("數據庫連接成功");
		} catch (Exception e) {
			e.printStackTrace();
			System.out.println("數據庫連接失敗");
		}
	}
}
