Property injection: Property injection uses the setXxx () method to inject Bean property values or dependent objects. Property inje

Spring also has an abstract bean. You only need to set the abstract attribute to true in the configuration file. It does not configure the class attribute because it will not be instantiated. When the bean of another spring inherits the abstract bean, You need to configure i

In general, we register a bean in spring and directlyid= "WebSocket" class= " Com.sdyy.common.spring.websocket.WebsocketEndPoint "/>This creates an object bean for us, using the Websocketendpoint construction method (which is no parameter).———————————————————————————— Dividing line —————————————————————————————————————————————But there is another way to register

Common annotations for Spring beans@Component: usually annotations, available for any bean@Repository: Typically used to annotate the DAO layer, which is the persistence layer@Service: Typically used to annotate service tiers, or services tiers@Controller: Typically used to annotate the controller layer, which is the control layerAutomatic detection of classes and the registration of beansDefining beansThe

Assembly also has a unique drawback: when there are multiple constructors, spring cannot choose exactly which constructor to initialize, so it also runs out of the exception. AutoDetect: The best self-assembly.When spring Initializes a bean with the autowire= "AutoDetect" set, it is first assembled with a constructor. If there are multiple beans or cons

1. servlet container The entire servlet lifecycle seems to be handled by the servlet container. If you place it in a spring container for creation, the servlet object can be created by the spring container, but the servlet container may not know that the servlet exists because it is not in its container. Therefore, the servlet should be handed over to the Web server and not to
