Second, the annotation is divided into two categories: 1, a class is the use of beans, that is already configured in the XML file with the bean to use, complete the attributes, methods of assembly; For example, @autowired, @Resource, can be passed through the Bytype (@Autowired), ByName (@Resource) The way to get the bean; 2, a class is registered Bean, @Compon

Eliminates redundant parent-class configuration, such as transaction management: Because there is no target attribute in the declaration, it must be declared as an abstract class, that is, abstract = true; Attention By default,ApplicationContext (not beanfactory) instantiates all singleton beans. So it's important to note that if you just want to use a (parent) bean definition as a template and it specifies the class attribute, you have to set

Scan package (profile) 2. Annotations for specific functions ( instantiation function) @Component general annotations: instantiating objects @ Controller: Instantiating objects of the control layer

We know that in spring2.0, there are two types of beans except singleton and prototype. By default, three types of beans are added: request, session, and global session. The added beans are mainly used in Web applications. This article does not want to analyze the usage of the three types of beans, but simply analyzes the implementation principle of the framework. Spring2.0 adds a scope interface to indicate the bean range. Public interface scope { Ob

In addition to component scanning and automatic assembly, there are Java code-based assembly and XML-based assembly.There are some scenarios where we cannot use automatic assembly, for example, we are going to assemble the components in our third-party library into our application, and the automatic assembly is not valid because automatic assembly can only scan packages in this application.At this point we're going to choose between code-based assembly and XML-based assembly, before we say that

Bromon originality, please respect copyright After so long mixing in the Java World, I have been asked the most questions since I broke away from the deep-rooted Java cainiao community. The first question is "What books should I read when I learn java ", the second is "What is J2EE ". The first question is confusing, and the second question is hard to explain. The J2EE framework is huge, with 13 core technologies. It is too complicated to explain. The concept of J2EE is often abused. What is a J

Spring core learning (5) inject beans into Bean-Parse dependencies, beanbean- Preface: start to learn the core idea of Spring and learn it through a simplified version of Spring code. Content: 1.

What exactly is the bean's life cycle like in spring?1. The container looks up the bean's definition information and instantiates it2. Using dependency injection, spring configures all the Bean's properties according to the Bean definition information3. If the bean implements the Beannameaware interface, the factory calls the Bean's Setbeanname () method to pass the Bean's ID4. If the
