The spring container first loads the parent container generated by Servletcontextlistener (corresponding applicationcontext.xml), and SPRINGMVC (corresponding Mvc_dispatcher_ Servlet.xml) produces a sub-container. The instance of the @service annotation assembled when the sub-container controller is scanned for assembly is not transacted, that is, a service with no transaction capability, and the service that the parent container initializes is a guar
The springmvc framework is mainly centered around the dispatcherservlet core. It intercepts requests and assigns them to the corresponding processor for processing, and then returns the results to users. Including annotation-driven controllers, request and response information processing, view parsing, localization parsing, file uploading parsing, exception handling, form binding, etc.
Springmvc is implemented based on model2. Using the processor to separate models, views, and controls, springm
Now the mainstream web MVC framework, in addition to struts this main force, followed by spring MVC, so this is a programmer need to master the mainstream framework, the framework is more choice, to deal with the changing needs and business, the implementation of the program is more natural.

I personally think that it is not very difficult to use the framework. The key is to understand its ideas, which is very helpful for us to improve programming. However, if you don't use it, you can talk about your thoughts on paper !!! First technology, then thinking. Practice.

Currently, the mainstream web MVC framework is not only the main force of struts, but also spring MVC. Therefore, this is also the mainstream framework that programmers need to master. There are more frameworks to choose from, when dealing with changing needs and businesses, there will naturally be more feasible solutions. However, to flexibly use

After the project is established, there will be a bunch of errors because the corresponding jar has not been introduced locally. Here's how to fix it:When you click OK, you'll download the required content from the Web. The content is not much, but very slow. Generally, the download completion error disappears. If it fails, try again.If you try it a few times, it may be the wrong package. You need to remove the download to the local content and download it again.Delete the directory of the speci
Using spring MVC has been around for 2 years, but still stuck in the use stage, feeling like this is not the way to go, so still want to go deep to explore.

Spring and SPRINGMVC, as the default framework for the Bean Management container and the MVC layer, have been adopted by many Web applications, while in practice, many XML-based configuration methods have been replaced by the powerful annotation functionality, but in actual projects, There are some strange exceptions when configuring spring and SPRINGMVC, such as
Spring MVC framework. The bank example shows how to model and build simple applications. The sample application contains some technologies (such as dependency injection) that have been learned, but mainly demonstrates the features of spring MVC.

The view parser provided by Spring MVC uses Viewresolver for view parsing to implement a rendering model in the browser. Viewresolver can parse multiple views such as JSPs, velocity templates, freemarker templates, and XSLT.The two most important interfaces of the spring processing view are viewresolver and view. The Viewresolver interface provides a mapping betw
