springboot项目整合nsq，消费者直连nsqd

　　　　项目需要用到nsq，并且是单点的，网上看到的springboot整合nsq都是先连接lookup后，从lookup获取nsqd的连接信息。由于本项目用到了docker，映射的端口都不是原始端口了。而lookup分发的连接nsqd还是默认的4150端口。所以是连不通的。这时候需要直连nsqd，撇开lookup。

　　　　查看官网  https://nsq.io/clients/client_libraries.html

 

　　　　由于要用到认证，所以只能选择   nsq-j   。翻看点进去的文档。有个名字是直连消费者的类：  DirectSubscriber  

　　　　看api以及父类的api，感觉可用。

　　加入依赖包：
