Ignore missing properties during Jackson JSON deserialization in Java

Question

In the example

class Person {
   String name;
   int age;
}

If the JSON object has a missing property \'age\',

{
  name :          


        

Answer 1

Annotation based approach is a better way for ignoring but If needed. The manual way of deserialization:

ObjectMapper mapper = new ObjectMapper().configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
Person       person = mapper.readValue(jsonFileReader, Person.class);
