To achieve an interface, constantly take data from the database, can be controlled to start and stop, the language java, framework ssm, would like to ask if there are any components available?

piecemeal idea:
can you write a method in the interface at the beginning to receive the request, and then cycle through the database data? But what should I do when I stop? Have thought about in the timer, but there is no mature train of thought, hope to point out. Thank you
data about tens of thousands of items, I do not know whether there will be a performance impact.
