Question: Is it possible to override Include.NON_NULL defined in the POJO while creating the ObjectMapper?
Explanation:
Suppose I have a POJO as below:
@JsonInclude(Include.NON_NULL)
class POJO {
String name;
String description;
//Constructors, Getters & Setters, etc
}
And a test class as below:
class Main {
public static void main(String args[]) {
POJO p = new POJO();
ObjectMapper mapper = new ObjectMapper();
String jsonString = mapper.setSerializationInclusion(Include.ALWAYS)
.writerWithDefaultPrettyPrinter()
.writeValueAsString(p);
//jsonString should contain empty name & description fields, but they doesn't
}
}
