This may be the limitations of DisplayTag, its page pages are like this:
If there is 10,000 beans in a list, according to its mechanism, if it is the first page (n, each page), it will take the first n data, then remove the remaining 10000-n strips, when you click When the page "2", it wraps a circle from the background, putting the data of the second page, that is, record the N 1-2 N strips, and deletes the remaining. In this way, it achieves a flipping and prevents memory usage.
However, in any case, it still has an action that takes out all the numbers, and it is possible to cause memory overflow in the case of maximum data.
