Java framework is too much, a search on the internet a large basket, there is no understanding of what.
I still use my experience to describe the framework of the Java EE.
1. First force pushes the struts2 frame, which is the most classic frame (can say no "one"). can help you quickly build out an MVC model. (Note: Struts1 is rarely used, and there are many problems, it is highly recommended to use STRUTS2).
The 2.Spring framework, which is the second-ranked framework (I am personally ranked, non-authoritative), is where its "dependency injection" and "inversion of control" are all about. Simply put, the parameters are injected into the container when the program is running, as if it were to the V3 version.
3. Persistent layer Frame Select Hibernate and Ibatis. Hibernate automation ability, the development of large-scale applications can save development time, Ibatis small and concise, flexible.
4.Jquery is the following prototype after another excellent javacript framework, encapsulated a lot of JavaScript methods, is the development of JSP framework, is currently popular in general development, are using struts2+spring+hibernate ( Ibatis) integration, front end with jquery or other similar frameworks.
For simple systems, sometimes a framework of spring MVC is used.
