I have a pretty standard Java POJO. Let's call it Dog:
Dog.java has a series of fields. In Java, convention says field names should start with a lower case. This means I have:
- public String name;
- public String dogType;
- public String weight;
At the same time, I have a requirement on my JSON format that the JSON members (name, dogType, and weight) all be written with a capital letter at the beginning i.e. Name, DogType, and Weight.
I am using Jackson.
If I use the standard serialization code as below, I get JSON member names written exactly the same way they are in Java.
ObjectMapper mapper = new ObjectMapper();
String json = mapper.writerWithDefaultPrettyPrinter().writeValueAsString(jReq);
System.out.println(json);
To address my problem, I have 2 options:
- either I use the Jackson annotation
@JsonProperty(value="DogType"), or - I use a naming strategy as described in the API.
My question is: is there a clean way of doing it?
There are quite a few questions on SO about this that explain both ways:
But none go into the pros and cons.
My initial hunch is that I should go for the naming strategy. Is that a good approach or a bad one?
