clientid_mqtt clientid_谷歌分析空clientID - 腾讯云开发者社区

其中讲到了：消息堆积重复消费自不必说，你 ClientID 都相同了。本篇着重聊聊为什么会消息堆积。文章中讲到，初始化 Consumer 时，会初始化 Rebalance 的策略。...入参需要以下四个： ConsumerGroup 消费者组的名字 currentCID 当前消费者的 clientID mqAll 当前 ConsumerGroup 所消费的 Topic 下的所有的 MessageQueue...cidAll 当前 ConsumerGroup 下所有消费者的 ClientID 实际上是将某个 Topic 下的所有 MessageQueue 分配给属于同一个消费者的所有消费者实例，粒度是 By...而我们开篇提到的 Consumer 的 ClientID 相同，会造成什么？当然是 index 的值相同，进而造成 mod、averageSize、startIndex、range 全部相同。

nested exception is java.lang.IllegalStateException: PathVariable annotation was empty on param 0.

当时声明明Feign接口方法时候，使用@PathVariable注解的接口方法： @GetMapping("/account/{clientId}") public User get(@PathVariable...String clientId); path路径部分只有一个clientId变量，那么说在“was empty on param 0”，也就是说clientId值没有取到！...解决: 将@PathVariable修改为@PathVariable(value="clientId")的写法，明确带有value="clientId"！...@GetMapping("/account/{clientId}") public User get(@PathVariable(value="clientId") String clientId);
