本文介绍了如何将基于方法的安全性添加到Spring Boot项目？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想在Spring Boot项目中添加基于方法的安全性。
I want to add method based security to a Spring Boot project.
似乎所有我需要的是添加 PermissionEvaluator 和 MethodSecurityExpressionHandler beans，使用 @EnableGlobalMethodSecurity注释我的以及 WebSecurityConfigurerAdapter （prePostEnabled = true） @PreAuthorize（isAuthenticated（）和hasPermission（＃param，'somePermissionName'））的方法。
It seemed that all I would need is to add PermissionEvaluator and MethodSecurityExpressionHandler beans, annotate my WebSecurityConfigurerAdapter with @EnableGlobalMethodSecurity(prePostEnabled = true) and the method with @PreAuthorize("isAuthenticated() and hasPermission(#param, 'somePermissionName')").
但添加 PermissionEvaluator bean
@Bean
public PermissionEvaluator permissionEvaluator() {
HelloPermissionEvaluator bean = new HelloPermissionEvaluator();
return bean;
}
我得到 IllegalArgumentException ：配置默认servlet处理需要ServletContext：
I get an IllegalArgumentException: "A ServletContext is required to configure default servlet handling":
Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'defaultServletHandlerMapping' defined in class path resource [org/springframework/web/servlet/config/annotation/DelegatingWebMvcConfiguration.class]: Instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: Factory method [public org.springframework.web.servlet.HandlerMapping org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport.defaultServletHandlerMapping()] threw exception; nested exception is java.lang.IllegalArgumentException: A ServletContext is required to configure default servlet handling

我在网上找到的所有内容都与jUnit测试有关。为什么抛出这个异常？我错过了什么？我是否必须添加ServletContext bean，如果是，如何？
All I could find on the web is related to jUnit testing. Why is this exception being thrown? What am I missing? Do I have to add a ServletContext bean, and if so, how?
我的要求是Gradle，Spring Boot和java config（而不是XML配置）。最小和完整的来源如下：

推荐答案
尝试将 PermissionEvaluator 放在单独的中@Configuration class。您似乎在 ServletContext 准备就绪之前强制它被实例化（必须超级创建Spring Security过滤器以便这可能发生）。
Try putting the PermissionEvaluator in a separate @Configuration class. You appear to be forcing it to be instantiated before the ServletContext is ready (Spring Security filters have to be created super early so this can happen).
