spring 打印所有创建的beans

1，创建一个类，实现接口 BeanPostProcessor

package com.zuikc.web.controller;

import org.springframework.beans.BeansException;
import org.springframework.beans.factory.config.BeanPostProcessor;

public class GetBeansNames implements BeanPostProcessor {
    public Object postProcessBeforeInitialization(Object bean, String beanName) throws BeansException {
        return bean; // we could potentially return any object reference here...
    }
    //在创建bean后输出bean的信息
    public Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException {
        System.out.println("Bean ‘" + beanName + "‘ created : " + bean.toString());
        return bean;
    }
}

2，在application.xml 中加入刚才创建的类名的bean

<bean class="com.zuikc.web.controller.GetBeansNames" />

3，在启动tomcat的时候就会打印创建beans的名称
