本文应用 springboot 集成 IBM MQ 的客户端, 简略的实现音讯接管和发送逻辑.

这里的配置和上文中创立的队列信息统一

server.port=9111
## mq 的连贯 ip
project.mq.host=192.168.0.106
## mq 的连贯端口
project.mq.port=1414
## mq 的队列管理器名字
project.mq.queue-manager=QM144
## mq 的 java 客户端连贯通道
project.mq.channel=SYSTEM_DEF_SVRCONN
## mq 的用户名
project.mq.username=mqm
## mq 的明码
project.mq.password=Paic2023q2
## mq 的接管超时工夫
project.mq.receive-timeout=20000
## 收发队列名称（可选）project.mq.queuename=QUEUE1
