You are making it way to complex, to enable file uploading simply configure it correctly using properties in the application.properties. multipart.enabled=true And make sure you have spring-webmvc on your class path (judging from the annotations used you already have). However there is one other thing and that is that file...

spring boot rabbitmq MappingJackson2MessageConverter custom object conversion
java,json,rabbitmq,spring-boot,spring-amqp
Ok, I finally got this working. Spring uses a PayloadArgumentResolver to extract, convert and set the converted message to the method parameter annotated with @RabbitListener. Somehow we need to set the mappingJackson2MessageConverter into this object. So, in the CONSUMER app, we need to implement RabbitListenerConfigurer. By overriding configureRabbitListeners(RabbitListenerEndpointRegistrar registrar) we...

Timing Issue with Spring Boot Annotation Configuration

I don't think it is timing issue. You are "in conflict" with this spring feature (from http://docs.spring.io/spring/docs/current/spring-framework-reference/htmlsingle/) Even typed Maps can be autowired as long as the expected key type is String. The Map values will contain all beans of the expected type, and the keys will contain the corresponding...

The big difference between your code and the example is in the XML config example that myTargetConnectionFactory is actually a bean managed by Spring. You aren't doing that. You are just creating a new object Spring doesn't know about. The magic happens when setting the targetConnectionFactory of myConnectionFactory. Even though...
