基于插件方式实现动态可插拔式功能扩展，主要应用包括支付插件、注册、营销活动计算等。 定义抽象接口标记为扩展点，由插件扩展实现具体扩展点，实现插拔式扩展，增加其灵活性。

• 插件扩展

  // 1.实现插件扩展点
  // 2.使用注解Extension 标记为扩展 
  @Extension
  public class ProbeDevice implements DeviceReg {
  
      private static final String PROBE = "probe";
  
      @Override
      public String deviceType() {
          return PROBE;
      }
  
      @Override
      public RegRequest extractRegRequest(Map<String, String> headers, byte[] body) {
          RegRequest request = new RegRequest();
          request.setDeviceType(PROBE);
          request.setDeviceNo("201107010450");
          Map<String, String> extra = new HashMap<>();
          extra.put("name", "探针");
          extra.put("version", "20201112_10.1.5.102902@release");
          request.setExtras(extra);
          return request;
      }
  }
