application项目获取bean

　　对于web项目，编程方式获取bean如下：

1 WebApplicationContext wac = ContextLoader.getCurrentWebApplicationContext();
2 CrmHttpClientBuilder builder = (CrmHttpClientBuilder) wac.getBean("crmHttpClientBuilder");

　　但是对于应用类项目要如何获取呢？方式之一就是通过实现ApplicationContextAware接口。
　　1. 定义接口

 1 public class SpringContextUtil implements ApplicationContextAware {    
 2     // Spring应用上下文环境    
 3     private static ApplicationContext applicationContext;    
 4     /**  
 5      * 实现ApplicationContextAware接口的回调方法，设置上下文环境  
 6      *   
 7      * @param applicationContext  
 8      */    
 9     public void setApplicationContext(ApplicationContext applicationContext) {    
10         SpringContextUtil.applicationContext = applicationContext;    
11     }    
12     /**  
13      * @return ApplicationContext  
14      */    
15     public static ApplicationContext getApplicationContext() {    
16         return applicationContext;    
17     }
18     /**  
19      * 获取对象  
20      *   
21      * @param name  
22      * @return Object
23      * @throws BeansException  
24      */    
25     public static Object getBean(String name) throws BeansException {    
26         return applicationContext.getBean(name);
27     }    
28 }  

2. 在applicationContext里面定义bean；只有这样定义才可以在spring初始化加载的时候填充该类的applicationContext。
 <bean id="springContextUtils" class="brave.SpringContextUtil" />
3. 使用

1 CrmTracingFactoryBean beanFactory = (CrmTracingFactoryBean) SpringContextUtil.getBean("tracing");
2 beanFactory.setLocalServiceName("lorry-dubbo-good");
