Esta página descreve como usar o Pub/Sub em aplicativos Java criados com
o Spring Framework.
O Spring Cloud GCP tem vários módulos para enviar
mensagens para tópicos do Pub/Sub e receber mensagens de assinaturas do
Pub/Sub usando o Spring Framework. Use esses
módulos de maneira independente ou combine-os em diferentes casos de uso:
O Spring Cloud GCP Pub/Sub Starter
permite que você envie e receba mensagens usando classes
auxiliares e chame a biblioteca de cliente Java do Pub/Sub para cenários mais avançados.
Com os adaptadores de canal de integração do Spring para Pub/Sub, é possível conectar
os canais de mensagens da Spring Integration
ao Pub/Sub.
O Spring Cloud Stream Linker para Pub/Sub permite
usar o Pub/Sub como middleware de mensagens em aplicativos Spring Cloud Stream.
