使用EvaluationContextExtensionSupport和自定义PermissionEvaluator将Spring Boot 2.0.6迁移到2.1.0时'Invalid bean definition'

在Spring Boot 2.1.0中， EvaluationContextExtensionSupport 已弃用，https://docs.spring.io/spring-data/commons/docs/current/api/org/springframework/data/repository/query/spi/EvaluationContextExtensionSupport.html表示直接实施EvaluationContextExtension

即使它只是被弃用，它立即开始使用此堆栈跟踪进行此升级失败：

Caused by: org.springframework.beans.factory.support.BeanDefinitionOverrideException: Invalid bean definition with name 'methodSecurityInterceptor' defined in class path resource [org/springframework/security/config/annotation/method/configuration/GlobalMethodSecurityConfiguration.class]: Cannot register bean definition [Root bean: class [null]; scope=; abstract=false; lazyInit=false; autowireMode=3; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=org.springframework.security.config.annotation.method.configuration.GlobalMethodSecurityConfiguration; factoryMethodName=methodSecurityInterceptor; initMethodName=null; destroyMethodName=(inferred); defined in class path resource [org/springframework/security/config/annotation/method/configuration/GlobalMethodSecurityConfiguration.class]] for bean 'methodSecurityInterceptor': There is already [Root bean: class [null]; scope=; abstract=false; lazyInit=false; autowireMode=3; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=methodSecurityConfiguration; factoryMethodName=methodSecurityInterceptor; initMethodName=null; destroyMethodName=(inferred); defined in class path resource [ournamespace/configuration/MethodSecurityConfiguration.class]] bound.

    at org.springframework.context.annotation.ConfigurationClassBeanDefinitionReader.loadBeanDefinitionsForConfigurationClass(ConfigurationClassBeanDefinitionReader.java:141)
...and so on

我不认为这只是我们当前代码中所做的一个副作用 . 如果我根据https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-2.1-Release-Notes#bean-overriding允许bean覆盖 spring.main.allow-bean-definition-overriding=true ，那么我只是得到另一个异常 .

java.lang.IllegalStateException: Duplicate key org.springframework.data.spel.ExtensionAwareEvaluationContextProvider$EvaluationContextExtensionAdapter@10dfbbbb at java.util.stream.Collectors.lambda$throwingMerger$0(Collectors.java:133) ~[na:1.8.0_162]

但是，我甚至不想覆盖任何bean行为，目标是让Spring自定义权限评估器再次按照Spring的意图工作 .

This is how it did work in the last version:

在Spring Boot 2.0.6中，我们有以下内容来使我们的自定义PermissionEvaluator类工作：

一个扩展 EvaluationContextExtensionSupport 的类

import org.springframework.data.repository.query.spi.EvaluationContextExtensionSupport;
import org.springframework.security.access.expression.SecurityExpressionRoot;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.context.SecurityContextHolder;

public class SecurityEvaluationContextExtension extends EvaluationContextExtensionSupport {

    @Override
    public String getExtensionId() {
        return "security";
    }

    @Override
    public SecurityExpressionRoot getRootObject() {
        Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
            return new SecurityExpressionRoot(authentication) {
        };
    }
}

然后是一个使用我们的权限评估程序创建表达式处理程序的类，并使用带有 EvaluationContextExtension 的@Bean

import ournamespace.security.CustomPermissionEvaluator;
import ournamespace.security.SecurityEvaluationContextExtension;
import lombok.RequiredArgsConstructor;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.repository.query.spi.EvaluationContextExtension;
import org.springframework.security.access.expression.method.DefaultMethodSecurityExpressionHandler;
import org.springframework.security.access.expression.method.MethodSecurityExpressionHandler;
import org.springframework.security.config.annotation.method.configuration.GlobalMethodSecurityConfiguration;

@Configuration
@RequiredArgsConstructor
public class MethodSecurityConfiguration extends GlobalMethodSecurityConfiguration {

    private final CustomPermissionEvaluator permissionEvaluator;

    @Override
    protected MethodSecurityExpressionHandler createExpressionHandler() {
        DefaultMethodSecurityExpressionHandler expressionHandler =
                new DefaultMethodSecurityExpressionHandler();
        expressionHandler.setPermissionEvaluator(permissionEvaluator);
        return expressionHandler;
    }

    @Bean
    EvaluationContextExtension securityExtension() {
        return new SecurityEvaluationContextExtension();
    }
}

最后我们在一个基本上是空的类中有这个：

@EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfiguration extends WebSecurityConfigurerAdapter {
   ...
}

这是因为如果我们将它放在 MethodSecurityConfiguration 类中，自定义权限评估程序从未应用于所有方法 . 有问题的服务器是oauth2资源服务器，因此我们不在 WebSecurityConfigurerAdapter 中配置任何其他服务器 . 我们还实现了自己的 UserDetails ，如果这与新解决方案有任何相关性，我们会扩展 DefaultUserAuthenticationConverter .

我已尝试直接实现 EvaluationContextExtension 类，如弃用警告中所述 . 通过将extends接口更改为 implements EvaluationContextExtension ，这只是一个简单的修改 . 我也尝试过换成看似更新的包 org.springframework.data.spel.spi

我已经尝试删除我们自己的 SecurityEvaluationContextExtension 并直接返回https://docs.spring.io/spring-security/site/docs/current/api/org/springframework/security/data/repository/query/SecurityEvaluationContextExtension.html作为bean但由于某种原因，数据包在Spring Boot 2.1.0中不可用

我试过完全删除那个bean的定义 .

所有这些都会导致启动时出现各种“无效的bean定义”错误 .

有谁知道在哪里可以找到迁移指南或任何其他资源，了解它现在应该如何工作？

仅供参考，实际 CustomPermissionEvaluator 类：

import ournamespace.configuration.Constants;
import ournamespace.exception.InternalException;
import ournamespace.model.Account;
import ournamespace.model.Member;
import ournamespace.model.Project;
import ournamespace.repository.MemberRepository;
import ournamespace.service.ServiceUtil;
import lombok.RequiredArgsConstructor;
import org.springframework.security.access.PermissionEvaluator;
import org.springframework.security.core.Authentication;
import org.springframework.stereotype.Component;

import java.io.Serializable;

import static ournamespace.model.MemberStatus.JOINED;
import static ournamespace.model.ProjectRole.*;

@RequiredArgsConstructor
@Component
public class CustomPermissionEvaluator implements PermissionEvaluator {

    private final MemberRepository memberRepository;

    @Override
    public boolean hasPermission(Authentication auth, Object targetDomainObject, Object permission) {
        if (targetDomainObject == null)
            return false;

        if (!(permission instanceof String))
            return false;

        if (auth == null)
            return false;

        Account account = ServiceUtil.getAccount(auth);

        if (targetDomainObject instanceof Project)
            return hasPermissionOnProject(account, (Project) targetDomainObject, (String) permission);
        //and so on
    }
}

以及如何使用它的示例：

public interface ProjectRepository extends PagingAndSortingRepository<Project, UUID> {

    @Override
    @PreAuthorize("hasPermission(#project, " + Constants.WRITE + ")")
    <S extends Project> S save(@Param("project") S project);
}
