spring 调用一个接口的所有实现类的方法

1.定义接口（其实定义接口就是一个标记作用）

public interface ITeleCommunicatinService {

public void dealYaoXin(TeleCommunicating tc);

}

2.通过ApplicationContext  获取到所有的实现了这个接口的方法 然后调用所有

public void dealReferenceService(TeleCommunicating tc){

ApplicationContext ac = SpringUtil.getContext();

Map<String, ITeleCommunicatinService> result = ac.getBeansOfType(ITeleCommunicatinService.class);

if(null != result && !result.isEmpty()){

for(Map.Entry<String, ITeleCommunicatinService> entry:result.entrySet()){

// System.out.println(entry.getKey());//默认是类名（不带报名）

// System.out.println(entry.getValue().getClass());//类的全名输出

try {

ITeleCommunicatinService it = SpringUtil.getBeanByType(entry.getValue().getClass());

it.dealYaoXin(tc);

} catch (Exception e) {

e.printStackTrace();

}

}

}

}

3.当这个dealReferenceService被调用时 ，ITeleCommunicatinService这个接口的所有实现类就会都被调用实现的方法。
