1. 或者  
2. @Service  
3. public class SpringTool implements ApplicationContextAware {  
4.     private static ApplicationContext context = null;  
5.     @Override  
6.     public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {  
7.         context = applicationContext;  
8.     }  
9.     public static ApplicationContext getApplicationContext() {  
10.         return context;  
11.     }  
12.   
13.   
14. }  

或者@Servicepublic class SpringTool implements ApplicationContextAware {    private static ApplicationContext context = null;    @Override    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {        context = applicationContext;    }    public static ApplicationContext getApplicationContext() {        return context;    }}
