1, Spring boot and cloud build microservices, return data from JSON into XMLProblem: The Spingboot item itself is annotated with @restcontroller, and the return result is also in JSON format, but the XML format returned by both the consumer and the provider after the Eureka of the Springcloud is built. The produces= "Application/json" must be added to the provider-consumer approach, but is it useless to @restcontroller the integrated @responsebody in the annotation itself?Solution: Remove this
