API模块接收请求，推送到消息队列
router模块消费消息，分发到各个模块
每个模块消费消息，在推回API模块，因为api模块需要知道最终执行结果
API模块配置：
spring:
cloud:
stream:
bindings:
outbound-agent-state-list.destination: outbound.agent-state-list #生产
agent-state-list-reply-channel: #消费回调回来的消息
destination: outbound.agent-state-list-reply

durableSubscription: false
consumer.maxPriority: 10
rabbit.bindings:
outbound-agent-state-list.producer.routing-key-expression: '''router'''
agent-state-list-reply-channel.consumer.durableSubscription: false
@Component
public interface OutboundOutputChannels {

接收回调消息并出来业务逻辑
@Slf4j
