推荐答案

不要将数据库连接代码放在JSP中。将它放在普通的java类中并测试它是否正常工作。然后在需要显示结果时从JSP调用该Java类。这样你就可以将处理逻辑与表示逻辑分开，从而允许可以轻松阅读的可测试的，可重复使用的代码。

Don''t put the database connection code in a JSP. Put it in a normal java class and test that it works properly. Then call that Java class from the JSP when you need to display the results. That way you separate your processing logic from your presentation logic allowing for testable, reusable code which is also easy to read.
