Spring websocket: how convert easily the Message<?>'s payload to POJO in ChannelInterceptorAdapter

Question

I have a Spring App working with websocket

I can do the connection and send messages etc.

The @Controller is:

    @MessageMapping(\         


        

Answer 1

The AbstractMessageBrokerConfiguration provides this bean:

@Bean
public CompositeMessageConverter brokerMessageConverter() {

You need to inject this bean into your MessageChannelInterceptorAdapter and call its fromMessage(Message<?> message, Class<?> targetClass):

Notification notification = (Notification) this.messageConverter.fromMessage(message, Notification.class);
