Handling custom objects with JAX-RS SSE API

Information sent using the JAX-RS 2.1 SSE support (in Java EE 8) does not only have to be of String type – it supports Java primitives (Integer , Long etc.), JSON-B & JAX-B annotated types as well as custom objects whose encoding process (Java object to on-wire format) is defined using a MessageBodyWriter implementation

Here is simple example you can try out – no need to setup anything except Docker !

Meanwhile – here is the code snippet

To summarize

  • Multiple ​​OutboundSseEvents have been created – each differing in the data/media type (text, json, xml etc.)
  • the default SSE media type is TEXT_PLAIN, hence does not need to be explicitly specified when dealing with String data type
  • ​​​​​Employee class is a JSON-B annotated class
  • Customer is a JAX-B annotated class
  • Student has a custom MesaageBodyWriter implementation

For more details, just refer to the project

Cheers!
