Jackie

Simple JSON serialization and deserialization from/to object.

What is Jackie good for?

Yet another JSON object serializer/deserializer, that is small and relatively fast.

Example

Let have sample object class, that defines primitive structure.

JackieExample.java

package test.project;
import java.util.Date;
import cz.tvrzna.jackie.Jackie;
public class JackieExample
{
    private Long id;
    private String name;
    private boolean active;
    private Date createDate;
    public JackieExample()
    {
    }
    public JackieExample(Long id, String name, boolean active, Date createDate)
    {
        this.id = id;
        this.name = name;
        this.active = active;
        this.createDate = createDate;
    }
}

Object To JSON

Jackie jackie = new Jackie();
JackieExample example = new JackieExample(123456789l, "Jackie's example", true, new Date());
System.out.println(jackie.toJson(example));

and the result is

{"id":123456789,"name":"Jackie's example","active":true,"createDate":"2020-03-10T13:43:24"}

JSON To Object

final String json = "[{\"id\":123456789,\"name\":\"Jackie's example\",\"active\":true,\"createDate\":\"2020-03-10T13:43:24\"}]";
Jackie jackie = new Jackie();
JackieExample example = jackie.fromJson(json, JackieExample.class);
`

JSON To List

final String json = "[{\"id\":123456789,\"name\":\"Jackie's example\",\"active\":true,\"createDate\":\"2020-03-10T13:43:24\"}]";
Jackie jackie = new Jackie();
List<JackieExample> lstExamples = jackie.fromJson(json, List.class, JackieExample.class);
`

JSON To Map

final String json = "{0: {\"id\":123456789,\"name\":\"Jackie's example\",\"active\":true,\"createDate\":\"2020-03-10T13:43:24\"}}";
Jackie jackie = new Jackie();
Map<Integer, JackieExample> mapExample = jackie.fromJson(json, Map.class, Integer.class, JackieExample.class);
