二、核心代码：
1、Util包 【存放数据库连接工具】
① DBTool（数据库连接工具类）
package cn.ac.azure.util;import java.io.IOException;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.util.Properties;/*** 数据库连接工具类* @author **/
public class DBTool {private static String driver; //数据库驱动private static String url; //数据库连接地址private static String user; //数据库连接用户private static String password; //数据库连接密码static{//新建一个properties,用于读取db.properties配置文件Properties p=new Properties();//新建一个字符串,保存配置文件的路径String path="cn//ac//azure//util//db.properties";try {//调用Properties.load通过类加载获得配置文件的输入流p.load(DBTool.class.getClassLoader().getResourceAsStream(path));//读取配置文件中的配置参数driver=p.getProperty("driver"); //获取驱动url=p.getProperty("url"); //获取数据库连接地址user=p.getProperty("user"); //获取数据库用户password=p.getProperty("password"); //获取数据库密码try {//加载数据库驱动类到程序中Class.forName(driver);} catch (ClassNotFoundException e) {e.printStackTrace();throw new RuntimeException("加载驱动失败",e);}} catch (IOException e) {e.printStackTrace();throw new RuntimeException("找不到配置文件",e);}}/*** 获取数据库连接* @return 数据库连接对象* @throws SQLException 提醒调用者捕获异常,并在finally中关闭关闭异常*/public static Connection getConnetion() throws SQLException{//通过DriverManager获得数据库连接return DriverManager.getConnection(url, user, password);}/*** 关闭数据库连接* @param con*/public static void close(Connection con){if(con!=null){ //如果数据连接不为空try {//关闭数据库连接con.close();} catch (SQLException e) {e.printStackTrace();throw new RuntimeException("数据库关闭失败",e);}}}
// /**
// * 测试数据库连接工具是否可用
// * @param args
// */
// public static void main(String[] args) {
// Connection con=null;
// try {
// con=DBTool.getConnetion();
// System.out.println("数据库连接成功!");
// } catch (SQLException e) {
// System.out.println("数据库连接失败!");
// e.printStackTrace();
// }finally{
// DBTool.close(con);
// }
// }
}

先自我介绍一下，小编13年上师交大毕业，曾经在小公司待过，去过华为OPPO等大厂，18年进入阿里，直到现在。深知大多数初中级java工程师，想要升技能，往往是需要自己摸索成长或是报班学习，但对于培训机构动则近万元的学费，着实压力不小。自己不成体系的自学效率很低又漫长，而且容易碰到天花板技术停止不前。因此我收集了一份《java开发全套学习资料》送给大家，初衷也很简单，就是希望帮助到想自学又不知道该从何学起的朋友，同时减轻大家的负担。添加下方名片，即可获取全套学习资料哦
