Spring acts as the role of the management container in the SSH box fake. We all know that hibernate is used to make the persistence layer, because it makes JDBC a good package, programmers can not write a large number of SQL statements when interacting with the database.

At the Java One conference in 2005, Sun released all of the JDK 1.6,j2xx renamed JAVAXX,J2EE as Java EE. In March 2018, the Eclipse Foundation renamed Java EE as Jakarta EE.
Spring is a application framework that serves all levels: it provides the configuration base for the bean, AOP support, JDBC extraction framework, abstract transaction support, and so on. It has a very striking feature: if you don't need spring support at some level, you can use only one part of it without using string
In today's MVC Framework, it seems that webwork2 has gradually become the mainstream, and the combination of webwork2 + springframework has become increasingly popular. This seems to mean that the MVC framework provided by spring is far worse than webwork2, so we use webwork2 in succession. Indeed, spring's MVC framework
