spring mvc architecture diagram

for each request, the variables of the servlet life cycle such as request,session are encapsulated into a map, supplied for each action, and thread-safe, so in principle, is more memory-intensive.4, The interceptor implementation mechanism, STRUTS2 has its own interceptor mechanism, SPRINGMVC with the independent AOP way, so that Struts2 configuration file volume is still larger than SPRINGMVC.5. The SPRINGMVC entrance is the servlet, and Struts2 is the filter (it is noted here that the filter

here want to the 3 models to sum up small respectively. Let's go back to the MVC architecture model. I have been working in the past few years the first contact is MVC (then there are no two models, haha), then give me the most intuitive feeling is the M and V of the Implementation code separation, so that a program can have different presentation forms; C is u

so on. It means that we probably need more than one representation of a resource, for example one that contains the whole page wi Th all menus, one of the contains just the content, and maybe one that presents the data in a popup style.Progressive enhancement is a unobtrusive-in-a-do, so we don't have JavaScript generating HTML, we just use JavaScript For rendering, the history management, refreshing and validating based on server-generated data.The movie Database–an example applicationLearn th

First, we introduce the concept of MVC: MVC (Model View Controller) models, views, and controllers are a widely used structural design pattern. Model: is the data that needs to be displayed in the MVC design pattern. Under normal circumstances, the model needs to read data from the database, save the state of the model, and provide access to data and data mainten

layer and the business logic layer is too close, so between the presentation layer and the business logic layer to add a layer of control layer, by judging the performance layer from the request (that is, the user's request) to decide which business processing logic to invoke. This gradually evolved the MVC framework.MVC,That is, the model---view---controller, although MVC is also three layers, but not cor

In this chapter, I will describe the sample hierarchy and give a brief introduction to MyBatis. This article
