Hands-On Microservices with Spring Boot and Spring Cloud

Implementing the new composite API operations

Now, we can implement the composite create and delete methods!

The composite's create method will split up the aggregate product object into discrete objects for product, recommendation, and review and call the corresponding create methods in the integration layer:

@Overridepublic void createCompositeProduct(ProductAggregate body) {    try {        Product product = new Product(body.getProductId(),         body.getName(), body.getWeight(), null);        integration.createProduct(product);        if (body.getRecommendations() != null) {            body.getRecommendations().forEach(r -> {                Recommendation recommendation = new                 Recommendation(body.getProductId(),                 r.getRecommendationId(), r.getAuthor(), r.getRate(),                 r.getContent(), null
