application项目获取bean

　　对于web项目，编程方式获取bean如下：

 WebApplicationContext wac = ContextLoader.getCurrentWebApplicationContext();
 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

 public class SpringContextUtil implements ApplicationContextAware {
     // Spring应用上下文环境
     private static ApplicationContext applicationContext;
     /**
      * 实现ApplicationContextAware接口的回调方法，设置上下文环境
      *
      * @param applicationContext
      */
     public void setApplicationContext(ApplicationContext applicationContext) {
         SpringContextUtil.applicationContext = applicationContext;
     }
     /**
      * @return ApplicationContext
      */
     public static ApplicationContext getApplicationContext() {
         return applicationContext;
     }
     /**
      * 获取对象
      *
      * @param name
      * @return Object
      * @throws BeansException
      */
     public static Object getBean(String name) throws BeansException {
         return applicationContext.getBean(name);
     }
 }  

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

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