How to search Bean class operation in Spring, 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.

One configuration file

Second interface

Axe

Package org.crazyit.app.service;public interface Axe {public String chop ();}

Person

Package org.crazyit.app.service;public interface Person {public void useAxe ();}

Three Bean

Chinese

The setter method public void setAxe (Axe axe) of package org.crazyit.app.service.impl;import org.springframework.stereotype.*;import org.crazyit.app.service.*;@Componentpublic class Chinese implements Person {private Axe axe; / / axe {this.axe = axe;} / / implements the useAxe () method of the Person interface public void useAxe () {System.out.println (axe.chop ());}}

SteelAxe

Package org.crazyit.app.service.impl;import org.springframework.stereotype.*;import org.crazyit.app.service.*;@Componentpublic class SteelAxe implements Axe {public String chop () {return "Steel axe is really fast to cut firewood";}}

StoneAxe

Package org.crazyit.app.service.impl;import org.springframework.stereotype.*;import org.crazyit.app.service.*;@Componentpublic class StoneAxe implements Axe {public String chop () {return "stone axe chopping wood is so slow";}}

Four test classes

Package lee;import org.springframework.context.*;import org.springframework.context.support.*;public class BeanTest {public static void main (String [] args) {/ / create Spring container ApplicationContext ctx = new ClassPathXmlApplicationContext ("beans.xml"); / / get the name of all Bean instances in the Spring container System.out.println ("-" + java.util.Arrays.toString (ctx.getBeanDefinitionNames ();}}

Five test results

-[chinese, steelAxe, stoneAxe, org.springframework.context.annotation.internalConfigurationAnnotationProcessor, org.springframework.context.annotation.internalAutowiredAnnotationProcessor, org.springframework.context.annotation.internalRequiredAnnotationProcessor, org.springframework.context.annotation.internalCommonAnnotationProcessor, org.springframework.context.annotation.ConfigurationClassPostProcessor.importAwareProcessor, org.springframework.context.annotation.ConfigurationClassPostProcessor.enhancedConfigurationProcessor]
