如何在线程中获取spring 管理的bean

http://my.oschina.net/skyline520/blog/181158?fromerr=GjtR6Wec

spring xml中定义 

<!--spring 工具类-->

    <bean id="springContextUtil" class="com.skyline.pub.utils.SpringContextUtil"/>

SpringContextUtil的代码如下 

package com.skyline.pub.utils;

import org.springframework.beans.BeansException;

import org.springframework.context.ApplicationContext;

import org.springframework.context.ApplicationContextAware;

import java.util.Locale;

/**

 * Spring 获取 bean工具类

 */

public class SpringContextUtil implements ApplicationContextAware {

    private static ApplicationContext context = null;

    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {

        this.context = applicationContext;

    }

    public static <T> T getBean(String beanName){

        return (T) context.getBean(beanName);

    }

    public static String getMessage(String key){

        return context.getMessage(key, null, Locale.getDefault());

    }

}

然后在线程中直接使用 (注: uploadService 为spring 中配置的bean) 

@Override

    public void run() {

        UploadService uploadService = SpringContextUtil.getBean("uploadService");

        switch (sheetIndex){

            case 1:uploadService.updateMiddleSaleProcedure(start,limit); break;

            case 2:uploadService.updateProductCountProcedure();break;

            case 3:uploadService.updateMonthProcedure();break;

        }

        countDownLatch.countDown();

    }
