我有一个从队列监听并发布到多个队列的实现。因此,我实现了一个通用接口,通过传递不同主题的名称向它们发送消息。
假设:
我在用google云pubsub
spring cloud gcp依赖项版本:1.1.3.release
spring云依赖版本:greenwich.release
spring集成核心版本:5.1.7.0发布
spring cloud gcp starter发布子版本:1.1.3.release
我在干什么?我正在侦听一个队列并执行一些逻辑,然后手动将ack消息发送到同一个队列(可以看到下面方法中的consumer.ack()),并将另外两条消息发送到其他队列(电子邮件触发队列和对其他微服务的异步acking)。我做错了什么,我找不到办法,我找了很多,尝试了不同的东西。
Spring特性
spring.cloud.gcp:
project-id: theProjectId
credentials:
location: XXX.json
scopes: DEFAULT_SCOPES
pubsub:
enabled: true
publisher:
retry:
total-timeout-seconds: 120
initial-retry-delay-second: 5
subscriber:
executor-threads: 1
initial-retry-delay-seconds: 20
