converting activemq msg in spring boot - spring

Question

I am using spring boot to decode the jms message
configuration
#Bean
public JmsListenerContainerFactory<?> myFactory(ConnectionFactory connectionFactory,
DefaultJmsListenerContainerFactoryConfigurer configurer) {
DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
// This provides all boot's default to this factory, including the message
// converter
configurer.configure(factory, connectionFactory);
factory.setMessageConverter(this.jacksonJmsMessageConverter());
// You could still override some of Boot's default if necessary.
return factory;
}
#Bean // Serialize message content to json using TextMessage
public MessageConverter jacksonJmsMessageConverter() {
MappingJackson2MessageConverter converter = new MappingJackson2MessageConverter();
converter.setTargetType(MessageType.TEXT);
converter.setObjectMapper(new ObjectMapper());
return converter;
}
and I am able to receive the message, and decode the message
#JmsListener(destination = "myQueue", containerFactory = "myFactory")
public void receiveMessage(ActiveMQTextMessage msg) throws JMSException, IOException {
String text = msg.getText();
ObjectMapper mapper = new ObjectMapper();
MyObject obj = mapper.readValue(text, MyObject.class);
my problem is I don't want to call mapper.readValue(xxx) everytime, I prefer
to configure the mapper and conversion in the messageconverter bean, I the key
is to call the msg.getText() from the converter, but how do I get a reference of
of the msg in the converter, or there are smarter way to do it.

Answer 1

Spring do that for you since you have configured the MessageConverter of the factory by factory.setMessageConverter(this.jacksonJmsMessageConverter());
so use the argument like this :
#JmsListener(destination = "myQueue", containerFactory = "myFactory")
public void receiveMessage(MyObject obj) throws JMSException, IOException {
//do stuff with obj
}
