Comparing the enum constants in thymeleaf

Question

I have an enum, Constants:

enum Constants {
    ONE,TWO,THREE;
}

How can I compare the enum Constants in Thymeleaf.

Thank

Answer 1

I tend to add isXXX() methods to my enums:

enum Constants {
    ONE,TWO,THREE;
    public boolean isOne() { return this == ONE; }
    public boolean isTwo() { return this == TWO; }
    public boolean isThree() { return this == THREE; }
}

Then, if value is an instance of your enum, you can use th:if="${value.one}".
