Java连接各种数据库代码和驱动

Connection connection = null;
		try {
			Class.forName("com.mysql.jdbc.Driver");
			connection = DriverManager.getConnection("jdbc:mysql://127.0.0.1:3306/boxmanager", "username", "password");
		} catch (ClassNotFoundException e) {
			e.printStackTrace();
		} catch (SQLException e) {
			e.printStackTrace();
		}

try {
			String driver = "com.sybase.jdbc3.jdbc.SybDriver";
			Class.forName(driver).newInstance();
			String url = "jdbc:sybase:Tds:192.168.100.252:4500/myDB";//
			// myDB为你的数据库名
			Properties sysProps = System.getProperties();
			sysProps.put("user", username); // 设置数据库访问用户名
			sysProps.put("password", password); // 密码
			connection = DriverManager.getConnection(url, sysProps);
		} catch (Exception e) {
			e.printStackTrace();
		}

// 得到连接
		Connection ct = null;
		try {
			// 加载驱动
			Class.forName("oracle.jdbc.driver.OracleDriver");
			ct = DriverManager.getConnection(
					"jdbc:oracle:thin:@127.0.0.1:1521:simlink", "your username", "your pwd");
		} catch (ClassNotFoundException e) {
			e.printStackTrace();
		} catch (SQLException e) {
			e.printStackTrace();
		}

5、SqlServer连接

String driverName = "com.microsoft.jdbc.sqlserver.SQLServerDriver";
		String dbURL = "jdbc:microsoft:sqlserver://localhost:1433;databasename=li"; // 1433是数据库的端口，"li"是你的数据库名称
		String userName = "sa"; // sa是数据库的超级用户，最好不要换别的名字，权限问题
		String userPwd = "123456"; // sa的密码

		Connection dbConn = null;
		try {
			Class.forName(driverName).newInstance();
			dbConn = DriverManager.getConnection(dbURL, userName, userPwd);
			System.out.println("连接成功!");
		} catch (Exception e) {
			e.printStackTrace();
		}
