String-formatted date to JavaBean

[Raymon Wang]

Hi, ALl:

When converting form json-formated string to JavaBean, I met the
problem about java.util.Date converting.

the following is the Java file that I tested with:

    ========================================

        package json;

        import java.util.Date;

        import net.sf.json.JSONObject;

        public class Person {
            private Date birthday;

            public Date getBirthday() {
                return birthday;
            }

            public void setBirthday(Date birthday) {
                this.birthday = birthday;
            }

            public static Person  getInstance(String jsonVale) {
                return
(Person)JSONObject.toBean(JSONObject.fromObject(jsonVale),Person.class);
            }

            public static void main(String[] args) {
                String personJson = "{birthday:\"06/28/2008
17:00:00\"}";

                Person p = getInstance(personJson);

                System.out.println("Person's brithday: "+
p.getBirthday());
            }
        }

=====================================================
Running the class would report the following message:

Person's brithday: Thu Jun 19 13:57:39 CST 2008

As the result shows,"Thu Jun 19 13:57:39 CST 2008 " is not equal to
"06/28/2008 17:00:00". I know it may be related to JSONConfig, however
I dont solve it.

Would you please help me with that?

Thanks in advance!

public static Person getInstance(String jsonVale) { 
        return  (Person)JSONObject.toBean(JSONObject.fromObject(jsonVale),Person.class); 
}

changed to:

public static Person getInstance(String jsonVale) {
    JSONUtils.getMorpherRegistry().registerMorpher(new DateMorpher(new String[] {"MM/dd/yyyy HH:mm:ss"}) );
    return (Person)JSONObject.toBean(JSONObject.fromObject(jsonVale),Person.class);
}

i.e:
   add a sentence of "JSONUtils.getMorpherRegistry().registerMorpher(new DateMorpher(new String[] {"MM/dd/yyyy HH:mm:ss"}) );" to configure the Morpher.

You need to register a DateMorpher with that specific format, assuming you will handle dates in that format only. If not you may supply DateMorpher with more formats.

import net.sf.ezmoprh.object.DateMorpher

...
JSONUtils.getMorpherRegistry().registerMorpher(new DateMorpher(new String[]{"dd/MM/yyyy HH:mm:ss"}));
Person p = getInstance(personJson);
...
