JMS Application with Spring Boot

Spring JMS supports Message Converters. Some Message Converters are provided out of the box :

Message Converter What It Does
SimpleMessageConverter Converts Strings to and from TextMessage, byte arrays to and from BytesMessage, Maps to and from MapMessage, and Serializable objects to and from ObjectMessage. Spring uses SimpleMessageConverter by default
MappingJackson2MessageConverter Uses the Jackson 2 JSON library to convert messages to and from JSON
MarshallingMessageConverter Uses JAXB to convert messages to and from XML
MessagingMessageConverter Converts a Message from the messaging abstraction to and from a Message using an underlying MessageConverter for the payload and a JmsHeaderMapper to map the JMS headers to and from standard message headers

Developer can create custom message conversion functionality. Custom converter class must implement MessageConverter interface, which has two methods :

  • Message toMessage(Object object, Session session) – converts Java object to JMS message using the supplied Session to create the message object. Returns JMS Message.
  • Object fromMessage(Message message) – converts JMS message to Java object
