Message Converters Customization
Customize message converters to handle various data formats beyond JSON, such as Protobuf or Avro.
What are Message Converters?
In Spring WebSockets, message converters are like translators. They handle the magic of turning data from your application (like a Java object) into a format that can be sent over the network (like a JSON string or binary data), and vice-versa.
Think of them as intermediaries between your Java code and the raw WebSocket messages.
JSON: Spring's Default
By default, Spring Boot WebSockets are set up to use JSON (JavaScript Object Notation) for message conversion. This is handled by the MappingJackson2MessageConverter.
- JSON is human-readable and widely supported.
- It's great for most common use cases.
- Spring automatically converts your Java objects to JSON and back.
