package com.xyc.initanddestorybean.component;import org.springframework.beans.factory.DisposableBean;import org.springframework.beans.factory.InitializingBean;import org.springframework.stereotype.Component;import javax.annotation.PostConstruct;import javax.annotation.PreDestroy;/** * 可以使用注解@Component注册，也可以用xml配置文件： * <bean id="testComponent" class="com.xyc.initanddestorybean.component.TestComponent" init-method="postConstruct" destroy-method="preDestroy"></bean> * Created by xyc on 2017/8/20 0020. */@Componentpublic class TestComponent implements InitializingBean, DisposableBean {    /**     * 执行顺序-1，初始化Bean     */    @PostConstruct    public void postConstruct() {        System.out.println("执行postConstruct了......");    }    /**     * 执行顺序-2，初始化Bean，InitializingBean接口提供     *     * @throws Exception     */    @Override    public void afterPropertiesSet() throws Exception {        System.out.println("执行afterPropertiesSet了......");    }    /**     * 执行顺序-3，销毁Bean     */    @PreDestroy    public void preDestroy() {        System.out.println("执行preDestroy了......");    }    /**     * 执行顺序-4，销毁Bean，DisposableBean接口提供     *     * @throws Exception     */    @Override    public void destroy() throws Exception {        System.out.println("执行destroy了......");    }}
