SpringBeanFactoryUtils 源代码：

package com.common.common.util;
    
    import org.springframework.beans.BeansException;
    import org.springframework.context.ApplicationContext;
    import org.springframework.context.ApplicationContextAware;
    
    public class SpringBeanFactoryUtils   implements ApplicationContextAware {    
        private static ApplicationContext appCtx;    
        /**  
         * 此方法可以把ApplicationContext对象inject到当前类中作为一个静态成员变量。  
         * @param applicationContext ApplicationContext 对象.  
         * @throws BeansException  
         * @author wangdf 
         */    
         
        public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {    
            appCtx = applicationContext;    
        }  
           
        /** 
         * 获取ApplicationContext 
         * @return 
         * @author wangdf 
         */  
        public static ApplicationContext getApplicationContext(){  
            return appCtx;  
        }  
           
        /**  
         * 这是一个便利的方法，帮助我们快速得到一个BEAN  
         * @param beanName bean的名字  
         * @return 返回一个bean对象  
         * @author wangdf 
         */    
        public static Object getBean(String beanName) {    
            return appCtx.getBean(beanName);    
        }    
    }
