Boon - Long To Date
ObjectMapper class can be used to work with different date formats in JSON. It can be used to parse/generate long version of date.
Example
Following example is using ObjectMapper class to generate a Date string from a long version.
import java.util.Date; import org.boon.json.JsonFactory; import org.boon.json.ObjectMapper; public class BoonTester { public static void main(String args[]) { ObjectMapper mapper = JsonFactory.create(); String jsonString = "{\"name\":\"Mahesh\", \"age\":21, \"dateOfBirth\":976559400000}"; //mapper converts long to date automatically Student student = mapper.readValue(jsonString, Student.class); System.out.println(student.dateOfBirth); //by default mapper converts date to long jsonString = mapper.writeValueAsString(student); System.out.println(jsonString); } } class Student { public String name; public int age; public Date dateOfBirth; public Student(String name, int age, Date dateOfBirth) { this.name = name; this.age = age; this.dateOfBirth = dateOfBirth; } }
