[FIXED] Spring Security hasRole() not working

Issue

I'm facing a problem when using Spring Security && Thymeleaf, specifically when trying to use the hasRole expression. The 'admin' user has a role 'ADMIN' but hasRole('ADMIN') resolves to false anyway I try it

My 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 -->

results in:

1.admin
2.[ADMIN]
3.true
4.true
5.ADMIN
6."prints nothing because hasRole('ADMIN') resolves to false"
7."prints nothing because hasRole(#vars.role_admin) resolves to false"
8.false
9.false

I have enabled use-expressions in my security.xml file

<security:http auto-config="true" use-expressions="true">

And also included the SpringSecurityDialect in my config

<bean id="templateEngine"
      class="org.thymeleaf.spring4.SpringTemplateEngine">
    <property name="templateResolver" ref="templateResolver" />  
    <property name="additionalDialects">
        <set>
            <bean class="org.thymeleaf.extras.springsecurity4.dialect.SpringSecurityDialect" />
        </set>
    </property>      
</bean>

All the necessary dependencies in my pom.xml file

<!--Spring security--> 
    <dependency>
        <groupId>org.springframework.security</groupId>
        <artifactId>spring-security-core</artifactId>

        <scope>compile</scope>
    </dependency>

Role.java

@Entity
@Table(name = "roles")

    public class Role implements Serializable {
    
        @Id
        @Enumerated(EnumType.STRING)
        private RoleType name;
        //... getters, setters
    }

RoleType

public enum RoleType {

    ADMIN 
}

And Userhas a Set of Roles

Why is hasRole() not working?

I appreciate your help, thank you

Workaround

th:if="${#strings.contains(#authentication.principal.authorities,'ADMIN')}"

Solution

Try use hasAuthority instead hasRole inside HTML-tag.

sec:authorize="hasAuthority('ADMIN')"
