'How to check if list is empty using thymeleaf?

<div th:if="${tblUserList != null}">
 --content--
</div>

The above thymeleaf code is not working, where tblUserList is a list. So I want to check whether the list is empty instead of checking its null. How to do that?

Solution 1:[1]

You can do as follows:

<div th:if="${not #lists.isEmpty(tblUserList)}">
 --content--
</div>

Solution 2:[2]

With Thymeleaf 3.x.x you can validate list more elegant:

<div th:if="${tblUserList!=null and !tblUserList.empty}"></div>

or

<div th:if="${tblUserList!=null and !tblUserList.isEmpty()}"></div>

Solution 3:[3]

Or simply:

<div th:if="${!myList.empty}">

Solution 4:[4]

Instead of negating you could use thymeleafs inverted if unless

<div th:unless="${myList.empty}">
