是因为这个handler是无状态的吗？

是这样的，那个类只用作消息类型的判断和处理异常情况．没有拥有状态．:smiling_imp:
你说的对，只有确保ChannelHandler是线程安全的，才能使用@sharable. 👍
只有怎么判断和保证类的线程安全，需要我们开发人员自己的知识积累和判断了 👏

大佬 又有问题了 订阅跟发送qos都为2 订阅端接收不到消息是为什么

如果订阅者的qos<1 就能收到消息，这是为什么

我大概知道什么原因了，现在太晚了，对照一下mqtt的qos2的流程，再对比一下mqtt的级别码 能发现问题

大佬 我错了 应该是id重复的问题 不好意思最近有点忙
Publish 类下的 sendPublishMessage 方法 qos2 那个判断下面 new MqttPublishVariableHeader(topic, )这里的消息 重复了 我是抓了包之后发现 这条消息因为跟发送端的一直 好像被去重了，把这个改成其他的数字 就可以了 不好意思啊 最近有点忙 没怎么有时间看
