注意此日志中输出的最后一个caused by输出：(reply-code=530, reply-text=NOT_ALLOWED - vhost /testVHost not found, class-id=10, method-id=40)，原因是vhost没找到，在yml中配置是，virtual-host属性配置多加了个‘/’去掉即可。去掉后如下：

spring.rabbitmq:
  addresses: amqp://abc:abc@192.168.1.100:5672,amqp://abc:abc@192.168.1.101:5672,amqp://abc:abc@192.168.1.102:5672
  publisher-confirms: true
  virtual-host: testVHost  #注意此处前面没有/，也就是rabbit web管理界面上显示的vhost名字，在没有自定义vhost时，默认的vhost是 ‘/’
