How to use Jackson to deserialise an array of objects

First create a mapper :

import com.fasterxml.jackson.databind.ObjectMapper;// in play 2.3ObjectMapper mapper = new ObjectMapper();

As Array:

MyClass[] myObjects = mapper.readValue(json, MyClass[].class);

As List:

List<MyClass> myObjects = mapper.readValue(jsonInput, new TypeReference<List<MyClass>>(){});

Another way to specify the List type:

List<MyClass> myObjects = mapper.readValue(jsonInput, mapper.getTypeFactory().constructCollectionType(List.class, MyClass.class));

From Eugene Tskhovrebov

List<MyClass> myObjects = Arrays.asList(mapper.readValue(json, MyClass[].class))

This solution seems to be the best for me.

For Generic Implementation:

public static <T> List<T> parseJsonArray(String json,                                         Class<T> classOnWhichArrayIsDefined)                                          throws IOException, ClassNotFoundException {   ObjectMapper mapper = new ObjectMapper();   Class<T[]> arrayClass = (Class<T[]>) Class.forName("[L" + classOnWhichArrayIsDefined.getName() + ";");   T[] objects = mapper.readValue(json, arrayClass);   return Arrays.asList(objects);}
