1 @Override
2 public void afterPropertiesSet() throws Exception {
3 final RocketMQMessageListener annotation = MyConsumer.class.getAnnotation(RocketMQMessageListener.class);
4 InvocationHandler h = Proxy.getInvocationHandler(annotation);
5 Field hField = h.getClass().getDeclaredField("memberValues");
6 hField.setAccessible(true);
7 Map memberValues = (Map) hField.get(h);
8 memberValues.put("topic", topic);
9 memberValues.put("consumerGroup", consumerGroup);
10 }
11 此时 topic consumerGroup 就可以通过配置中心或者文件来动态配置
12 比如：
13 @Value("${dynamic.spring.rocketmq.topic}"
14 private String topic
