Question

I have a String with the following value:

[
  {
    "key1": "value11",
    "key2": "value12"
  },
  {
    "key1": "value21",
    "key2": "value22"
  }
]

And the following class:

public class SomeClass {
    private String key1;
    private String key2;
    /* ... getters and setters omitted ...*/
}

And I want to parse it to a List<SomeClass> or a SomeClass[]

Which is the simplest way to do it using Jackson ObjectMapper?

Answer 1

I finally got it:

ObjectMapper objectMapper = new ObjectMapper();
TypeFactory typeFactory = objectMapper.getTypeFactory();
List<SomeClass> someClassList = objectMapper.readValue(jsonString, typeFactory.constructCollectionType(List.class, SomeClass.class));
