Spring Security hasRole（）不工作

Question

我在使用Spring Security&Thymeleaf时遇到了一个问题，特别是在尝试使用hasRole表达式时。admin“用户有一个角色”admin“，但hasRole('admin')在尝试时解析为false

我得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 -->

结果如下：

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

我已经在security.xml文件中启用了use-expressions

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

并且在我的配置中包含了SpringSecurityDiscuale

<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>

    </dependency>

@Entity
@Table(name = "roles")

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

public enum RoleType {

    ADMIN 
}

而用户具有一组角色

为什么HasRole()不起作用？

我很感激你的帮助，谢谢。

th:if=“${#strings.contains(#authentication.principal.authorities,'admin')}”

尝试在html-tag中使用hasAuthority而不是hasrole。

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