In the java Enterprise application field, the powerful functions of ejbs are the same as the complicated configurations of ejbs, and they are also known for their difficulties in learning. But before, what can we do? You can only learn ejbs with a hard head. It is a bit of "understanding that there are tigers in the mountains and moving towards tigers. There has been an optimistic change in the form. The popularity of java open source has made the development of java Enterprise applications no l

EhCache is one of Hibernate's second-level cache technologies. It can store the queried data in memory or disk, saving the need to query the database again with the same query statement next time, greatly reducing the database pressure; EhCache usage notes When you use Hibernate to modify table data (save, update, delete, and so on), EhCache will automatically delete all the caches related to this table (this can achieve synchronization ). However, fo

the object is still in use. This can cause an important problem when trying to abstract the persistence layer through the DAO pattern. In order to fully abstract the persistence layer, all database logic, including open, closed sessions, cannot appear at the application level. Most often, the logic is hidden in the DAO's implementation class. A quick and poor solution is to avoid the DAO pattern and include the logic of the data connection in the application layer. This is feasible in small app

1. Is action thread-safe? If there is no way to ensure the thread security of action? If yes, explain the reasonIt is not thread-safe. Thread security can be ensured without declaring class variables. Because only one action instance exists, all threads share variables.
