JSF Convert dates for title attribute

问题

I need to put a date into the title attribute of an image so that it displays when the user puts the mouse over. Problem is I would like to change the date format.

Any ideas?

<ice:graphicImage value="bean.image" title="#{bean.date}"/>

回答1:

Either do it directly in a getter method

public String getDate() {
    return new SimpleDateFormat("yyyy-MM-dd").format(this.date); 
}

or grab JSTL's <fmt:formatDate>.

<fmt:formatDate value="#{bean.date}" pattern="yyyy-MM-dd" var="date" />
<ice:graphicImage value="bean.image" title="#{date}"/>

(which would not work inside repeating components like UIData)
