1. The beans package provides the basic functions for managing and operating beans programmatically. The context package adds applicationcontext, which enhances the beanfactory function in a more framework-oriented manner.
2. The context package is based on the applicationcontext interface in the org. springframework. Context package. It is derived from the beanfactory interface and provides all the features of beanfactory. To work in a more framework-oriented way, the context package also provi
The Struts framework has the advantages of modular components, flexibility and reusability, and simplifies the development of MVC-based Web applications. Hibernate is an open source object link ing framework. Spring is an open-source project and is currently very active.

People who have studied the spring framework will surely hear the two concepts of Spring's IOC (inversion of Control) and DI (Dependency injection), which, for beginners of spring, always feel that the two concepts of IOC and DI are ambiguous and difficult to understand. Today, we share some of the technologies on the Web. Daniel's understanding of the spring Fra
First, let's say one conclusion: unit tests are isolated from the spring container of the main project, that is, unit tests cannot access the main Project Spring container and need to load the spring container yourself.
Next is the code instance, where the Web master project is running, and you might see code like this in the unit test:
