【问题描述】：

所以，我想暂时禁用 spring 安全依赖，以执行几个任务。在 pom.xml 文件中，我这样注释掉它：

    <dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>
    <!--    <dependency>-->
    <!--        <groupId>org.springframework.boot</groupId>-->
    <!--        <artifactId>spring-boot-starter-security</artifactId>-->
    <!--    </dependency>-->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-thymeleaf</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.thymeleaf.extras</groupId>
        <artifactId>thymeleaf-extras-springsecurity5</artifactId>
    </dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-devtools</artifactId>
        <scope>runtime</scope>
        <optional>true</optional>
    </dependency>
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <scope>runtime</scope>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.springframework.security</groupId>
        <artifactId>spring-security-test</artifactId>
        <scope>test</scope>
    </dependency>
</dependencies>

但是，在我注释掉它之后，我刷新了 maven 依赖项，当我运行应用程序时，我在控制台中遇到了几个错误，例如：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'viewResolver' defined in class path resource [org/springframework/boot/autoconfigure/web/servlet/WebMvcAutoConfiguration$WebMvcAutoConfigurationAdapter.class]: Initialization of bean failed; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'thymeleafViewResolver' defined in class path resource [org/springframework/boot/autoconfigure/thymeleaf/ThymeleafAutoConfiguration$ThymeleafWebMvcConfiguration$ThymeleafViewResolverConfiguration.class]: Unsatisfied dependency expressed through method 'thymeleafViewResolver' parameter 1; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'templateEngine' defined in class path resource [org/springframework/boot/autoconfigure/thymeleaf/ThymeleafAutoConfiguration$ThymeleafDefaultConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.thymeleaf.spring5.SpringTemplateEngine]: Factory method 'templateEngine' threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'securityDialect' defined in class path resource [org/springframework/boot/autoconfigure/thymeleaf/ThymeleafAutoConfiguration$ThymeleafSecurityDialectConfiguration.class]: Post-processing of merged bean definition failed; nested exception is java.lang.IllegalStateException: Failed to introspect Class [org.thymeleaf.extras.springsecurity5.dialect.SpringSecurityDialect] from ClassLoader [jdk.internal.loader.ClassLoaders$AppClassLoader@1d44bcfa]

任何想法如何解决这个问题？

【问题讨论】：

如果这就是您注释掉的全部内容，它应该可以工作。该错误与注释掉的依赖无关。请检查您是否没有注释掉其他内容。

您排除了 Spring Security 但留在了 thymeleaf-extras-springsecurity5 依赖项中，这会触发 Thymeleaf 安装方言，由于没有 Spring Security 存在而失败。

你说得对，谢谢！

考虑将解决方案添加为答案并接受它或删除问题。谢谢！

【参考方案1】：

所以，我只是忘了禁用依赖项：thymeleaf-extras-springsecurity5。 把它注释掉后，它也工作得很好。
