如何使用Java获取数据库状态？

Question

I am new to the java programing and trying to develop an application. On my jsp page I am allowing user to enter the db details and then click on test button to check whether connection is set or not.

Answer 1

You can catch the SQLException from DriverManager.getConnection(). By this you can validate the connection.

Answer 2

If there is no Exception occurred while connecting with the given database details
you can tell connection is success.Else catch the exception and show message accordingly to the user

Answer 3

您可以使用jdbc触发"select 1"查询，并且如果没有引发任何异常，则可以说连接已完成。
