Convert JSON to Map

Question

What is the best way to convert a JSON code as this:

{ 
    \"data\" : 
    { 
        \"field1\" : \"value1\", 
        \"field2\" : \"value2\"
    }
}

Underscore-java library can convert json string to hash map. I am the maintainer of the project.

Code example:

import com.github.underscore.lodash.U;
import java.util.*;

public class Main {

    @SuppressWarnings("unchecked")
    public static void main(String[] args) {
        String json = "{"
            + "    \"data\" :"
            + "    {"
            + "        \"field1\" : \"value1\","
            + "        \"field2\" : \"value2\""
            + "    }"
            + "}";

       Map data = (Map) U.get((Map) U.fromJson(json), "data");
       System.out.println(data);

       // {field1=value1, field2=value2}
    }
}
