假设有一个Person类,
[code="java"]
public class Person{
private java.util.Date birthday;
// settor and gettor methods.....
}
[/code]
现在客户端那边传来如下的json规则的字符串String personJson = "{birthday:\"06/28/2008 17:00:00\"}",要用
JSONOjbect.toBean(JSONObject.from(personJson ),Person.class)方法来获得相应的Person实例时就出问题了,报错如下:
[code="java"]

Person's brithday: Thu Jun 19 13:57:39 CST 2008
[/code]
这个怎么解决?
以下是我做实验用的Java代码:
[code="java"]
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());
}
}
[/code]
[b]问题补充:[/b]
To ham:
你所说的那个方案是针对 bean --> Json的,而现在的问题是从Json到Bean.
[b]问题补充:[/b]
多谢各位的帮忙,现在这个问题解决了,也就是在toBean前加一句话:JSONUtils.getMorpherRegistry().registerMorpher(new DateMorpher(new String[] {"MM/dd/yyyy HH:mm:ss"}) );来配置记下Date转化时的Morpher就OK了,大家有兴趣的话可以试下.
Thanks a lot!
