First, preface:

Choosing an excellent MVC framework for the development team is a difficult task, and it requires a high level of experience and expertise in a wide range of possible scenarios. One of your decisions will affect the team's future years. There are too many things to consider:

1, easy to use, to improve the development efficiency. Put a small amount of energy on the frame, and most of the energy is on the business.

2, excellent performance, this is a most eye-catching topic.

3. Try to use the public framework (avoid the use of niche, private framework), the newly recruited developers have a number of technical accumulation in this area, reduce the impact of mobility and re-adaptation.

If you're still worrying about this, this is the best thing for you. Choose Spring MVC.

Spring MVC is currently the best MVC framework, and since the release of Spring 2.5, ease of use has been greatly improved thanks to the support for annotation configurations. The Spring 3.0 is more complete and achieves the transcendence of Struts 2. More and more development teams are now choosing Spring MVC.

Struts2 is also a very good MVC architecture, with many advantages such as good structure, interceptor ideas, and rich functionality. But here is the disadvantage, Struts2 due to the use of value stack, OGNL expression, struts2 tag library, etc., will lead to the performance of the application degradation, should avoid the use of these features. The STRUTS2 multi-layer interceptor, multi-instance action performance is very good. You can refer to an article I wrote about the comparison between spring MVC and Struts2 and Servlets, "Struts2, Springmvc, servlet (JSP) performance comparison test"

Advantages of SPRING3 MVC:

1, Spring3 MVC is simple to use, low learning cost. The learning difficulty is less than the redundant function that STRUTS2,STRUTS2 does not use too much. Oh, of course this is not the deciding factor.

2, Spring3 MVC is easy to write a good performance program, Struts2 to be careful to write good performance program (refers to the MVC part)

3, Spring3 MVC flexibility is beyond your imagination, the spring framework of the extension of the legendary, Spring3 MVC certainly will not lag behind, not because of the use of the MVC framework and feel any restrictions.

STRUTS2 's many advantages:

1, the veteran of the well-known framework, from the Struts1 accumulated a large number of user groups. Rich technical documentation.

2, other aspects slightly ... (hehe, isn't it fair?) )

second, the core class and interface:

Let's take a look at some important interfaces and classes. Now do not know what they are do not matter, first mixed face ripe, for later know them to play a foundation.

Dispatcherservlet--Front Controller

Handlermapping interface--mapping of processing requests

Implementation classes for the Handlermapping interface:

simpleurlhandlermapping mapping a URL to a controller through a configuration file

defaultannotationhandlermapping maps a URL to a controller class via annotations

Handleradapter interface--mapping of processing requests

The Annotationmethodhandleradapter class, through annotations, maps a URL to the method of the Controller class

Controller interface--controllers

Since we have used the @controller annotation, the class that added the @controller annotation annotation can assume the responsibility of the Controller (Action),

So we don't have to use this interface.

Handlerinterceptor interface--Interceptor

Without graphs, we implement this interface ourselves to complete the work of the Interceptor.

Implementation class for the Viewresolver interface

The Urlbasedviewresolver class passes a configuration file and gives a view name to the

Internalresourceviewresolver class, than the above class, joined the JSTL support

View interface

Jstlview class

Localresolver interface

Handlerexceptionresolver interface--Exception handling

Simplemappingexceptionresolver Implementation Class

Modelandview class

No diagram.

Third, core flowchart

This picture is my personal painting, there is not rigorous place, we deal with the look. It's better than not watching.
