@ Componet (value= "xxx")

@ Scope (value= "singleton") / / Singleton. The default is Singleton.

Public class MyCass () {}

The above annotation instantiates in the spring container an object of type MyClass, the object name is xxx, and the first letter of the class name is myClass.

Public class TestClass {

/ / injection

@ Resource (name= "xxx") / / do not write name. The default is to match the class name in lowercase by default.

Public void method (MyClass T)

{}

}

Spring assembly principle: if you annotate the class name that needs to be instantiated with componet, the object will be instantiated into the spring container

When you need to use this object to instantiate other objects, you can use the @ Resource annotation before the set methods of other objects to use this object in the container
