1. The containers instantiate every bean,populate their properties,and call the init method,which makes the bean ready to be used.During the shutdown of the application,the destroy method of the bean is invoked.
  2. The init and destroy methods are used to perform initialization and cleanup operations.
  3. Below diagram shows the Spring Bean life cycle.

    http://invitationalshootout.com/2015/06/ forex trend indicator package com.java2learn.core; import org.springframework.beans.BeansException; import org.springframework.beans.factory.DisposableBean; import org.springframework.beans.factory.InitializingBean; import org.springframework.context.ApplicationContext; import org.springframework.context.ApplicationContextAware; public class SpringBeanDemo implements ApplicationContextAware,InitializingBean,DisposableBean { private String message; public SpringBeanDemo() { System.out.println("SpringBeanDemo is instantiating."); } public void setMessage(String message) { this.message = message; System.out.println("Inside setMessage method"); } public String getMessage() { return message; } @Override public void destroy() throws Exception { System.out.println("Inside destroy method"); } @Override public void afterPropertiesSet() throws Exception { System.out.println("Inside afterPropertiesSet method"); } @Override public void setApplicationContext(ApplicationContext applicationContext)throws BeansException { System.out.println("Inside setApplicationContext method:"); } }

  2. Create the Spring configuration file

    <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"> <bean id="springBean" class="com.java2learn.core.SpringBeanDemo"> <property name="message" value="Hello Spring Bean!!"></property> </bean> </beans>
