ObjectMapper class can be used to work with different date formats in JSON. It can be used to parse/generate a long of data.
Example
The 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\":\"Zafrul\", \"age\":21, \"dateOfBirth\":917327917730}";
//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;
}
}
Output
Given below is the output of the code −
Tue Dec 12 00:00:00 IST 2000
