Comparing 2 strings in thymeleaf

String comparison in Java

As you know in Java, we cannot compare 2 strings with the == equal operator. The == operator is used to compare object references, not the primitive values. So effectively it checks if they have the same memory address, which they don’t.

String comparison in Thymeleaf

If you want to compare 2 strings in thymeleaf with th:if

Wrong code:

th:if=”${userAdapter.user.userStatus}==’ADMIN’”

Instead, you have to use Thymeleaf’s strings.equals() method like this

Correct code:

th:if=”${#strings.equals(userAdapter.user.userStatus, ‘ADMIN’)}”

If you want to do the opposite of !equals, add ! infront of # like ${!#string.equals(a,b)}
