Best way to map json to a Java object

I'm using restTemplate to make a rquest to a servlet that returns a very simple representation of an object in json.

{
     "id":"SomeID"
     "name":"SomeName"
}

And I have a DTO with those 2 fields and the corresponding setters and getters. What I would like to know is how to create the object using that json response without having to "parse" the response.

Solution

  • Personally I would recommend Jackson. Its fairly lightweight, very fast and requires very little configuration. Here's an example of deserializing:

    @XmlRootElement
public class MyBean {
    private String id;
    private String name;

    public MyBean() {
        super();
    }

    // Getters/Setters
}


String json = "...";
MyBean bean = new ObjectMapper().readValue(json, MyBean.class);
