Spring specifies what the execution method of InitMethod and DestroyMethod is for bean. In view of this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

1. Create a class

/ * * @ author: zhaobin * @ date: 10:16 * @ description on 2021-11-25: * / public class Cat {public Cat () {System.out.println ("initialize the constructor first");} public void start () {System.out.println ("start method");} public void destroy () {System.out.println ("destroy method");}}

two。 Create a bean

/ * * @ author: zhaobin * @ date: 10:14 on 2021-11-25 * @ description: * / @ Configurationpublic class EventConfig {@ Bean (initMethod = "start", destroyMethod = "destroy") public Cat create () {Cat cat = new Cat (); System.out.println ("next initialize the start method in Cat") / / return a pet class, so that you have this Cat class in the spring container to execute the start method in initMethod.

3. The order of loading is: create method-> constructor of Cat class-> output print in create method-> start method in Cat class-> destroy method in Cat class
