Problem description?? When we use the Spring Framework for project development, the Autosire mechanism in spring is often used in order to configure the bean, and autowire can be divided into ==byname== and ==bytype== depending on the injection

Let's sort out the automatic assembly autowire section of spring today. Here we want to solve the following problems:1. What is automatic assembly?2 What is the significance of automatic assembly?§ 3 what types of automatic assembly are available?§ 4

Annotations such as @Autowired and @resource inject beans from the spring container into properties, while annotations such as @component are managed in the spring container.@Autowiredspring2.1 allows the user to annotate the bean's attribute

Dependency injection (ioc di) Two Methods of dependency injection: 1. set Injection When Spring requires the set injection method, Bean needs to provide a construction method without parameters. And provides a property setter method. For example:

1. Using spring annotations to inject properties 1.1. How we injected attributes before using annotationsimplementation of the class: Class Usermanagerimpl implements Usermanager { private Userdao Userdao; public void Setuserdao

First, the automatic assembly modelThe following is the automatic connection mode, which can be used to instruct the spring container to use automatic connection for dependency injection. You can use the Autowire property of an element to specify

The official definition of automatic assembly is as follows:The Spring IoC container can automatically assemble (autowire) the association between beans that collaborate with each other. Therefore, if possible Let spring specify the bean

The notes are not updated because they have been busy for the past few days. Spring. Net has the ability to automatically assemble, that is, spring. Net can automatically distinguish the collaborative objects of an object through the definition of

The spring container can automatically assemble the relationships between the mutual collaboration beans, which helps reduce the configuration of the XML without having to write a large number of and elements based on the spring application.
