各种数据库JDBC连接方式

1.Oracle数据库

import java.sql.SQLException;

public class OracleDBUtils {
	/**
	 * 获取数据库连接
	 */
	public static Connection getConnection() {
		Connection conn = null;
		
		try {
			Class.forName("oracle.jdbc.driver.OracleDriver"); 
			String url="jdbc:oracle:thin:@localhost:1521:orcl"; //orcl为数据库的SID 
			String user="test"; 
			String password="test"; 
			conn= DriverManager.getConnection(url,user,password);  
			
		} catch (SQLException e) {
			e.printStackTrace();
		} catch (ClassNotFoundException e) {
			System.out.println("未找到加载器，加载驱动程序失败！！！");
			e.printStackTrace();
		}catch(Exception e) {
			e.printStackTrace();
		}
		
		return conn;
	}
}
