Customizing property ordering

The order of properties appearing in the resulting JSON can also be customized using the @JsonbPropertyOrder annotation on the Java classes. For example, we can use the lexical order, as shown in the following example:

@JsonbPropertyOrder(PropertyOrderStrategy.LEXICOGRAPHICAL) 
public class Movie { 
     .... 
} 

Upon serializing the previous object, the resulting JSON attributes will be displayed sorted in alphabetical order; you can try this yourself.

There are three available values for the property order configuration property, as shown in the following table with an explanation for each:

Order Strategy	Explanation
ANY	The resulting JSON attributes are not guaranteed to be in any specific order.
LEXICOGRAPHICAL	The resulting JSON attributes are shown in alphabetical order.
REVERSE	The resulting JSON attributes are shown in reverse alphabetical order.
