如何在 spring 启动应用程序中启动和停止 google pubsub 订阅者？

Question

I have implemented a google pubsub topic-subscriber (spring-boot and cloud stream framework) using the spring.io guides example.

App starts consuming the messages as soon as the app is up. I would like to implement an api where we start and stop the consumption of messages on demand.

Let's say GET /pubsub/messages -> start the subscriber -> gets messages (synchronous or asynchronous) -> stops the subscriber.

Any thoughts would be helpful.

See this answer Stop consume message for Stream listener

You need to add the actuator Boot starter and inject the BindingsEndpoint to stop/start the binding.

You can set autoStartup to false to prevent the binding from starting immediately.
