从spring容器中取出注入的bean 工具类，代码如下：

package com.hyzn.fw.util;import org.springframework.beans.BeansException;import org.springframework.context.ApplicationContext;import org.springframework.context.ApplicationContextAware;import org.springframework.stereotype.Component;/**  * @ClassName: SpringBeanUtil * @Description: TODO  Spring获取bean的工具类，可用于在线程里面获取bean  *                  需要在 类上 标注 @Component ，否则没有将此工具类 注入到spring容器中 * @author xbq * @version 1.0 * @date 2017-2-21 下午2:30:38 */@Componentpublic class SpringBeanUtil implements ApplicationContextAware{        private static ApplicationContext applicationContext = null;            // 获取ApplicationContext对象    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {          SpringBeanUtil.applicationContext = applicationContext;      }        /**     * @Title: getBeanByName     * @Description: TODO  通过bean的名字来获取Spring容器中的bean     * @param beanName     * @return     * @return: Object     */    public static Object getBeanByName(String beanName) {          if (applicationContext == null){              return null;          }          return applicationContext.getBean(beanName);      }        public static 
     
       T getBean(Class
      
        type) {          return applicationContext.getBean(type);      }  }
