我在使用Spring Security && Thymeleaf时遇到问题,特别是在尝试使用hasRole表达式时.'admin'用户有一个'ADMIN'角色,但hasRole('ADMIN')无论如何我会尝试将其解析为false

我的HTML:

1.<div sec:authentication="name"></div> <!-- works fine -->
2.<div sec:authentication="principal.authorities"></div> <!-- works fine -->

3.<div  sec:authorize="isAuthenticated()" >true</div> <!-- works fine -->
4.<span th:text="${#authorization.expression('isAuthenticated()')}"></span> <!-- works fine -->

5.<div th:text="${#vars.role_admin}"></div> <!--Works fine -->
6.<div  sec:authorize="${hasRole('ADMIN')}" > IS ADMIN </div> <!-- Doesnt work -->
7.<div  sec:authorize="${hasRole(#vars.role_admin)}" > IS ADMIN </div> <!-- Doesnt work -->
8.<div th:text="${#authorization.expression('hasRole(''ADMIN'')')} "></div> <!-- Doesnt work -->
9.<div th:text="${#authorization.expression('hasRole(#vars.role_admin)')}"></div> <!-- Doesnt work -->

结果是:

1.admin
2.[ADMIN]
3.true
4.true
5.ADMIN
6."prints nothing …
