我在使用Spring Security和Thymeleaf时遇到了问题,特别是在尝试使用hasRole表达式时。'admin'用户具有'ADMIN'角色,但无论如何尝试,hasRole('ADMIN')
都会解析为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 -->
结果为:
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
我已在我的security.xml文件中启用了use-expressions。
<security:http auto-config="true" use-expressions="true">
我还在我的配置中包含了SpringSecurityDialect
<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>
在我的pom.xml文件中的所有必要依赖项
<!--Spring security-->

Role.java
@Entity
@Table(name = "roles")
public class Role implements Serializable {
@Id
@Enumerated(EnumType.STRING)
private RoleType name;
//... getters, setters
}
角色类型
public enum RoleType {
ADMIN
}
用户拥有一组角色。
为什么hasRole()
无法工作?
非常感谢您的帮助,谢谢。
解决方法
th:if="${#strings.contains(#authentication.principal.authorities,'ADMIN')}"
ROLE_ADMIN
而不是ADMIN
。 - woemlerADMIN
