Use Pulsar Client: Apache Pulsar provides an official Java client library that allows you to interact with Pulsar topics and consume/produce messages. You can use this client library within your Spring application.
Configure Connection and Consumer/Producer: You would configure the Pulsar client with connection details, such as the Pulsar broker URL, and create Pulsar producer and consumer instances. These configurations can be done in your Spring application configuration files.
Message Processing:Implement your message processing logic within Spring components, such as @Service classes or message listeners. When messages are received from Pulsar, you can use these components to process the messages.
Error Handling: Handle exceptions and errors that may occur during message processing, such as handling message deserialization errors or communication issues with Pulsar.
Spring Integration: Depending on your requirements, you may integrate Pulsar with other Spring components and technologies, such as Spring Boot, Spring Integration, or Spring Cloud Stream, to create more complex and robust messaging pipelines.
