title: How to map a nested value to a property using Jackson annotations?
body: <p>Let's say I'm making a call to an API that responds with the following JSON for a product:</p>
  
  <pre><code>{
    "id": 123,
    "name": "The Best Product",
    "brand": {
       "id": 234,
       "name": "ACME Products"
    }
  }
  </code></pre>
  
  <p>I'm able to map the product id and name just fine using Jackson annotations:</p>
  
  <pre><code>public class ProductTest {
      private int productId;
      private String productName, brandName;
  
      @JsonProperty("id")
      public int getProductId() {
          return productId;
      }
  
      public void setProductId(int productId) {
          this.productId = productId;
      }
  
      @JsonProperty("name")
      public String getProductName() {
          return productName;
      }
  
      public void setProductName(String productName) {
          this.productName = productName;
      }
  
      public String getBrandName() {
          return brandName;
      }
  
      public void setBrandName(String brandName) {
          this.brandName = brandName;
      }
  }
  </code></pre>
  
  <p>And then using the fromJson method to create the product:</p>
  
  <pre><code>  JsonNode apiResponse = api.getResponse();
    Product product = Json.fromJson(apiResponse, Product.class);
  </code></pre>
  
  <p>But now I'm trying to figure out how to grab the brand name, which is a nested property. I was hoping that something like this would work:</p>
  
  <pre><code>    @JsonProperty("brand.name")
      public String getBrandName() {
          return brandName;
      }
  </code></pre>
  
  <p>But of course it didn't. Is there an easy way to accomplish what I want using annotations? </p>
  
  <blockquote>
    <p>The actual JSON response I'm trying to parse is very complex, and I don't want to have to create an entire new class for every sub-node, even though I only need a single field.</p>
