The Event-driven model in spring, also known as the Publish-subscribe pattern, is a typical application of the observer pattern, as summarized in the previous blog post, http://www.cnblogs.com/fingerboy/p/5468994.html Here's a look at the application of the observer pattern in Spring.The structure of the spring Event-driven model.　　Start by clarifying the concepts of several

Spring containerThe spring container can help you manage all your bean objects. Jargon is called IOC control inversion. In a traditional program. The generation of objects is completed by the developer. In control reversal, the object's generation is all given to the frame. This advantage is to reduce the dependence of the program.The Bean's life cycle in spring

Control reversal (IoC) Control inversion: the so-called control inversion means that the application itself is not responsible for the creation and maintenance of dependent objects, and the creation and maintenance of dependent objects are the responsibility of external containe

Spring Study Notes-Why use Spring In our project, we don't need Hibernate, Struts, or ibatis. But we use Spring in almost every project. Why? Let's analyze the advantages of Spring:1. Reduce coupling between components to achieve decoupling between different layers of software2. You can use many services provided by co
