Question

我有一个带有此pom.xml的SpringBoot应用程序：

...
<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.6.RELEASE</version>
        <relativePath/> 
    </parent>

<!-- Spring Security -->
        <dependency>
            <groupId>org.thymeleaf.extras</groupId>
            <artifactId>thymeleaf-extras-springsecurity4</artifactId>
        </dependency>
...

，它工作正常。然后，我将SpringBoot版本更新为

...
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.0.RELEASE</version>
        <relativePath/> 
    </parent>

        <dependency>
            <groupId>org.thymeleaf.extras</groupId>
            <artifactId>thymeleaf-extras-springsecurity4</artifactId>
            <version>3.0.4.RELEASE</version> 
        </dependency>
...

我在1个模板中遇到此错误：

Exception evaluating SpringEL expression: "#authorization.expression('hasRole(''ROLE_ADMIN'')')" (template: "tdk/common/menu" - line 87, col 21)

此处是模板：

 <li th:if="${#authorization.expression('hasRole(''ROLE_ADMIN'')')}"    class="menu-principal pure-menu-item" th:classappend="${activeMenuItem == ‘tdkMessages'} ?  pure-menu-selected">
                    <a href=“/tdk/list" class="pure-menu-link">
                        <i class="fas fa-cloud-download-alt fa-lg fa-fw"></i>&nbsp; tdk
                    </a>
                </li>

Answer 1

Thymeleaf现在具有针对Spring Security 5的特殊扩展名/方言。您将需要使用它而不是Spring Security 4的扩展名/方言。

<dependency>
    <groupId>org.thymeleaf.extras</groupId>
    <artifactId>thymeleaf-extras-springsecurity5</artifactId>
</dependency>

应该做到这一点，<version>由Spring Boot管理，因此您不需要添加它。

将SpringBoot从2.0.6.RELEASE更新到2.1.0.RELEASE后评估SpringEL表达式的异常
