The way springMvc automatically equips beans

Spring is a framework that is often used in our projects. Using bean injection in spring can reduce code. Project injection of beans is the most basic functionality in a project.

There are three main injection methods in spring.

1. java display injection

　　

2.xml display injection

　　Configure <context-component-scan base-package = 'com.bao'> in the configuration xml file in the project

3. Implicit injection of java

　　1) Add the @compoment annotation to the class

　　@compoment(name)

　　public class beanZhu imp beani ();

　　2) Increase the config of spring scan bean

　　@configuration

　　@ComponentScan

　　public class beanConfig()

Note that @name can be used to replace the @component alternative.
