java - Spring Security hasRole()无法正常工作

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”用户的角色为“ADMIN”，但无论如何我尝试将hasRole('ADMIN')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 because hasRole('ADMIN') resolves to false"
7."prints nothing because hasRole(#vars.role_admin) resolves to false"
8.false
9.false

我在security.xml文件中启用了use-expressions

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

并且在我的配置中还包含了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>

我的pom.xml文件中的所有必需依赖项

<!--Spring security-->
    <dependency>
        <groupId>org.springframework.security</groupId>
        <artifactId>spring-security-core</artifactId>
        <version>4.0.1.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.security</groupId>
        <artifactId>spring-security-web</artifactId>
        <version>4.0.1.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.security</groupId>
        <artifactId>spring-security-config</artifactId>
        <version>4.0.1.RELEASE</version>
    </dependency>

    <!--Thymeleaf Spring Security-->
    <dependency>
        <groupId>org.thymeleaf.extras</groupId>
        <artifactId>thymeleaf-extras-springsecurity4</artifactId>
        <version>2.1.2.RELEASE</version>
        <scope>compile</scope>
    </dependency>

角色.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
}

并且User具有Set的Role为什么hasRole()不起作用？
感谢您的帮助，谢谢
解决方法th:if="${#strings.contains(#authentication.principal.authorities,'ADMIN')}"

最佳答案

尝试在HTML标签内使用hasAuthority代替hasRole。

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