constructor: autowiring is done based on constructor arguments, meaning Spring will look for beans with the same type as the constructor arguments.įor example, let’s create the store bean with its dependency, the item, injected into it by type.If there’s more than one bean of that type, the framework throws an exception. When the container executes the annotated method, it registers the return value as a bean within a BeanFactory. The Bean is a method-level annotation used to declare a spring bean. This means Spring will look for a bean with the same type of the property to set. The following annotations provide metadata to Spring to control how to instantiate, configure, and wire the beans together. The constructor of MyService takes an instance of M圜omponent as a parameter, which Spring will automatically inject when creating an instance of MyService.
