Struts2 Ognl标记中的日期比较

Question

My requirement is to display a date from db and the status message to inform whether the date coming from db is past date, current date or a future date.

I'm displaying the date from db by

<s:property value="%{selObj.lastdate}"/>

Now how to get the current date in OGNL tags, I have tried

<s:propery value="%{new Date()}"/>

I need this current date to compare with selObj.lastdate and find out the date is passed?

Answer 1

要获取当前日期/时间，您不需要修改您的操作类，只需将此行添加到您的jsp：

<s:property value="@java.util.Calendar@getInstance().time" />

Answer 2

If you can modify your action side:

You can try to write a getter as like:

public Date getCurrentDate(){
    return new Date();
} 

at your Java(Action) side.

So you can get that value:

<s:property value="currentDate"/>

at your JSP side.

Answer 3

That's is the right way to compare and get current date. I have to suggest to display a date in UI, should use like this;

<s:date name="currentDate"  format="dd-MM-yyyy" />

It will be formatted date.
