This article introduces the relevant knowledge of "how to achieve Hibernate Struts pagination". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

First, there are two structures in Hibernate Struts pagination:

1. In Action, all the records are queried by DAO, then added to the session or request object, passed to the client, and paged by JSP. This method is very convenient when the amount of data is small, and does not affect the speed.

two。 In Action, only one page of records are queried through DAO at a time, and then passed to the JSP page.

This structure is good for programs with a large amount of data, but for a small amount of data, it will increase the request to the server and increase the load on the server.

2. Hibernate query

Since the fixed-point quantitative query method for the database is directly provided in Hibernate, I use the second method.

Such as:

Take out 100 records from Article 10, 000.

Query Q = session.createQuery ("from Cat as c"); q.setFirstResult (10000); q.setMaxResults (10000); List l = q.list (); so much for "how to implement Hibernate Struts pagination".
