Re: The different output with Date whether the Http request have application/json

[哈哈哈哈]

HI Thanks for reply
Yes its does change to what i format
but not with if the request with application/json
app still return millionseconds

and after a day for testing
I finally find out its nothing about struts2-json-plugin


its struts2-rest-plugin cause the issue !!


if i add this plugin
The Date Object will turn to millionseconds
But I didnt see any word about it at official page
https://struts.apache.org/plugins/rest/

here is my action code ===

import java.util.Date;
import com.opensymphony.xwork2.Action;
import com.opensymphony.xwork2.ModelDriven;
public class TmpAction implements ModelDriven<Object> {
  private Date model = new Date();
  public Date getModel() {
    return model;
  }
  public void setModel(Date model) {
    this.model = model;
  }
  public String index() {
    return Action.SUCCESS;
  }
}

===
here is my struts.xml ===
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
        "-//Apache Software Foundation//DTD Struts Configuration 2.5//EN"
        "http://struts.apache.org/dtds/struts-2.5.dtd";>

<struts>
<constant name="struts.json.dateformat" value="dd/MM/yyyy" />
   <package name="api" extends="json-default"
        namespace="/api">
        <action name="/tmp/*"
            class="TmpAction" method="index">
            <result type="json">
                <param name="root">model</param>
            </result>
        </action>
    </package>
</struts>
