thymeleaf下拉菜单应为“rparen())”，但为“lparen(()”

尝试用thymeleaf枚举填充html中的下拉菜单时出错。我不确定问题出在哪里：

<select>
<option th:each="complexity : ${T(cz.test.sc.entity.common.Complexity.values()}"
        th:value="${complexity}"
        th:text="${complexity}">
</option>
</select>

枚举：

public enum Complexity {
    VERY_SIMPLE(1) {
        public String toString() {
            return "1. Very Simple";
        }
    },
    SIMPLE(2) {
        public String toString() {
            return "2. Simple";
        }
    },
    MEDIUM(3) {
        public String toString() {
            return "3. Medium";
        }
    },
    COMPLEX(4) {
        public String toString() {
            return "4. Complex";
        }
    },
    VERY_COMPLEX(5) {
        public String toString() {
            return "5. Very Complex";
        }
    };

    Complexity(int id) {
        EnumUtil.setEnumOrdinal(this, id);
    }
}

例外情况：

我认为你的循环中缺少了正确的偏执。 ${T(cz.test.sc.entity.common.Complexity.values()} 应该是 ${T(cz.test.sc.entity.common.Complexity).values()} .
