This page describes how to use Pub/Sub in Java applications built with the Spring Framework.
Spring Cloud GCP has several modules for sending messages to Pub/Sub topics and receiving messages from Pub/Sub subscriptions using the Spring Framework. You can use these modules independently or combine them for different use cases:
- Spring Cloud GCP Pub/Sub Starter lets you send and receive messages using helper classes and call the Pub/Sub Java client library for more advanced scenarios.
- Spring Integration Channel Adapters for Pub/Sub let you connect Spring Integration Message Channels with Pub/Sub.
- Spring Cloud Stream Binder for Pub/Sub lets you use Pub/Sub as messaging middleware in Spring Cloud Stream applications.
