In traditional Java applications, bean lifecycle is very simple. Java keyword new is used to instantiate Bean (maybe non-serialized ). This is enough. On the contrary, bean lifecycle is more detailed in spring containers. Understanding the lifecycle of spring bean is very important, because you may need to use the oppo

In the previous blog mentioned in the container launch Get Beandefinition object has a scope property. This property controls the scope of the Bean object. This section describes the scope and life cycle of the bean, and how it does not. I. Scope of the BeanThe bean container starts reading the bean's XML configuration file, and then converts each

1. Named Bean Each bean has one or more identifiers. These identifiers must be unique within the container in which they are loaded. A bean often has and has only one identifier, but if more than one name is required, additional aliases can be considered. XML-based configuration source file, you can use the ID or the name attribute to specify the

Bean's life cycle:The Spring IOC container can manage the Bean's life cycle,Spring allows custom tasks to be performed at specific points in the Bean life cycle.The process by which the Spring IOC container manages the Bean's life cycle:1 Creating a Bean instance from a constructor or factory method2 setting values and references to other beans for the Bean's properties3 Call the

Configuring a factory bean is usually created by the application using new, and in order to separate the creation and use of the object, the factory pattern is used, where the application takes the creation and initialization responsibility of the object to the factory object. In general, the application has its own factory object to create the bean. If you give the application's own factory object to sprin

Default ScopeIn Spring IOC containers, there are two default bean scopes: Singleton, the Bean's lifetime and container are synchronized once the bean is created, the bean is destroyed only when the container is closed, the bean with the same ID is instantiated only once during the lifetime of the container, an

Bean's Chinese meaning is "beans", as the name implies JavaBean is aJava applet。 JavaBean actually refers to a special Java class that is typically used toimplement some of the more common simple functions, and can be easily reused or inserted into other applications. All Java classes that follow certain programming principles can be called JavaBean.I. Java Bean Technology OverviewJava beans are Java-based component models that are composed of propert

First, what is a bean?1, Java object-oriented, the object has methods and properties, then you need an object instance to invoke methods and properties (i.e. instantiation);2. All classes that have methods or attributes need to be instantiated to use these methods and attributes in order to be figurative;3. Rule: All subclasses and classes with methods or attributes are added to the annotations of the registered b
