IOC (DI): In fact, the concept of the core of the spring architecture is not so complex, much less obscure as some books describe. Java programmers know that every business logic in a Java program requires at least two or more objects to work together, and usually each object uses a syntax such as new object to complete the application of the partner object when

Where to load the configured resources, actually to the lower classes to do, such as Filesystemxmlapplicationcontext, is to the file system to read an XML form of the ApplicationContext Classpathxmlapplicationcontext to the class loading path to read the ApplicationContext.

Brief introductionaspect-oriented programming (AOP) provides another way to think about the structure of a program, making up for the lack of object-oriented programming (OOP). In addition to classes (classes), AOP provides slices. Cut to the point of concern for modularity, such as transaction management across multiple types and objects. (These attention-point terms are often referred to as crosscutting (crosscutting) concerns.) ） One of the key components of

are equivalent, but from the name of the annotation class it is easy to see that the 3 annotations correspond to the persistence layer, the business layer, and the control layer (the WEB layer), respectively. Although there is nothing new about these 3 annotations and @Component, Spring will add special features to them in future releases. Therefore, if a WEB application uses a classic three-tier hierarchy, it is best to annotate the classes in the h

Concept One, what spring is 1 is an application framework that provides strong support for the development of applications, such as support for transaction processing and persistence, and so on.2 is a bean container that manages the entire lifecycle of the Bean object, maintaining the various existing state of the bean, such as instantiating the Bean object, destroying it, single instance of the bean and mu
