En esta página, se describe cómo usar Pub/Sub en aplicaciones Java compiladas con el framework Spring.
Spring Cloud GCP tiene varios módulos para enviar mensajes a temas de Pub/Sub y recibir mensajes de suscripciones de Pub/Sub mediante el framework Spring. Puedes usar estos módulos por separado o combinarlos en diferentes casos de uso:
Con Spring Cloud GCP Pub/Sub Starter, puedes enviar y recibir mensajes con clases auxiliares y llamar a la biblioteca cliente de Java para Pub/Sub para situaciones más avanzadas.
Los adaptadores de canales de integración de Spring para Pub/Sub te permiten conectar canales de mensajes de integración de Spring con Pub/Sub.
El vinculador de Spring Cloud para Pub/Sub te permite usar Pub/Sub como middleware de mensajería en las aplicaciones de Spring Cloud Stream.
