how to display data in JSTL for list containing objetcs?

In request attribute I have list of objects (say user objects) so how can I loop through it display data on my jsp page? Can I use <c:foreach> but then how I can say that it is User object and access properties of that?

Solution

  • JSTL/EL doesn't care about the exact type. All you need to ensure is that the object in question has a getter method for the given property so that you can just specify the property name.

    Imagine,

    public class User {

    private Long id;
    private String name;
    private Integer age;

    // Getters/setters.
}

    then you can loop over a List<User> like follows:

    <table>
    <c:forEach items="${users}" var="user">
        <tr>
            <td>${user.id}</td>
            <td><c:out value="${user.name}" /></td>
            <td>${user.age}</td>
        </tr>
    </c:forEach>
</table>

    That's it.
