String url = "jdbc:oracle:thin:@localhost:1521:orcl"; //获取连接URL
String user = "scott"; //连接用户名
String password = "tiger"; //连接密码
 conn = DriverManager.getConnection(url, user, password); //获取数据库连接
if (conn != null) {

}
} catch (Exception e) {
e.printStackTrace();
}
return conn; //返回Connection实例
}
public static void main(String[] args) {
