环境：

spring 注解

版本3.1

需求：

自定义的类中获取注解的bean

实现：

1.实现ApplicationContextAware方法：

@Componentpublic class SpringBeanUtils implements ApplicationContextAware {	private static ApplicationContext applicationContext;	public void setApplicationContext(ApplicationContext arg0)			throws BeansException {		applicationContext = arg0;	}	public static 
    
      T getBean(String id, Class
     
       clasz) {		return applicationContext.getBean(id, clasz);	}}
     
    

2.直接获取：

KeyProperties instance=SpringBeanUtils.getBean("com.linkrmb.KeyProperties",				KeyProperties.class);
