Spring Data Repository的Aspect建议不起作用

本文介绍了Spring Data Repository的Aspect建议不起作用的处理方法，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

我试图创建一些切入点，然后在存储库建议之前，以便在Spring Boot中为Spring Data中的某些存储库启用过滤实体管理器。我在项目中也有Web和服务层，而AspectLogging也适用于两者。但我不能为存储库做同样的事情。我已经挣扎了2天，我尝试了很多东西来解决它。我几乎阅读了关于此的所有文档，问题和主题（代理问题CGlib和JDK代理等）。我用jhipster来创建项目。

im trying to create some pointcuts and before advices for Repositories in order to enable filtering over entitymanager for some Repositories in Spring Data in Spring Boot. i also have web and service layer in project and AspectLogging works for both. But i couldnt do same for repositories. i have been struggling for 2 days and i tried so many things for fix it. i read almost every docs, issues and threads about this( proxy issues CGlib and JDK Proxy etc). i used jhipster for creating project.

我无法使用CrudRepository部署除@Pointcut之外的应用程序。甚至它部署的@Before也没有在Repository中调用方法调用。我想我有类似的问题，如下面的问题。 代理混淆

i cant deploy Application except @Pointcut with CrudRepository. and even its deployed @Before isnt called for a method call in Repository. i think i have a similar Problem like in following question. proxy confusion

有谁知道它可能是什么？

Does anyone know what its could be ?

类和配置如下所示。

存储库：

public interface ApplyRepository extends JpaRepository<Apply,Long>,QueryDslPredicateExecutor<Apply> { public Page<Apply> findAll(Predicate predicate, Pageable p); } ... }

数据库配置：

@Configuration @EnableJpaRepositories("com.xxx.zzz.business.repository") @EnableJpaAuditing(auditorAwareRef = "springSecurityAuditorAware") @EnableTransactionManagement//(proxyTargetClass = false) public class DatabaseConfiguration { ....

AspectJ配置：

AspectJ Config:

@Configuration @EnableAspectJAutoProxy(proxyTargetClass = true) // @EnableLoadTimeWeaving(aspectjWeaving = ... ) public class LoggingAspectConfiguration { ...

系统架构：

@Aspect public class SystemArchitecture { /** * A join point is in the web layer if the method is defined * in a type in the com.xyz.someapp.web package or any sub-package * under that.W */ @Pointcut("within(com.xxx.zzz.web.rest..*)") public void inWebLayer() { } /** * A join point is in the service layer if the method is defined * in a type in the com.xyz.someapp.service package or any sub-package * under that. */ @Pointcut("within(com.xxx.zzz.business.service..*)") public void inServiceLayer() { } /** * A join point is in the data access layer if the method is defined * in a type in the com.xyz.someapp.dao package or any sub-package * under that. */ @Pointcut("within(com.xxx.zzz.business.repository..*)") public void inDataAccessLayer() { } /** * All layers */ @Pointcut("inWebLayer() || inServiceLayer() || inDataAccessLayer()") public void inALL(){ } @Pointcut("within(org.springframework.data.repository.CrudRepository)") //@Pointcut("execution(*org.springframework.data.repository.Repository+.* (..))") //@Pointcut("execution(* com.xxx.zzz.business.repository+.*(..))") //@Pointcut("execution(* org.springframework.data.jpa.repository.JpaRepository+.*(..))") //@Pointcut("execution(* com.xxx.zzz.business.repository.ApplyRepository.*(..))") public void inDATAExec(){} }

FilterAspect：

FilterAspect:

@Aspect @Transactional public class FilterAspect { private final Logger log = LoggerFactory.getLogger(this.getClass()); @PersistenceContext private EntityManager entitymanager; @Before("com.xxx.zzz.aop.logging.SystemArchitecture.inDATAExec())") // "execution(* com.xxx.zzz.business.repository.InvoiceRepository.*(..))" public void doAccessCheck() { if (TransactionSynchronizationManager.isActualTransactionActive() && SecurityUtils.isAuthenticated()) { Session session = entitymanager.unwrap(Session.class); session.enableFilter("GLOBAL_FILTER").setParameter("customerId", SecurityUtils.getCurrentCustomerId()); } }

编辑：我解决了问题。它以某种方式与错误的切入点和名称相关。我试图在存储库中更改自定义注释的切入点。它不适用于方法或类级别。我在下面的链接中读到了有关此问题。 建议1 建议2 即将挣扎数小时用于目标和注释。但没有结果。 是否真的不可能在Spring Data Repositories中添加自定义注释来提供建议？

i solved problem. it was related somehow to wrong pointscuts and names. i tried to change pointcuts for custom annotation in Repository. it doesnt work for method or class level. i read in following links issues about this. advice 1 advice 2 im struggling for hours for target and annotation. but no result. is it really imposible to add custom annotations in Spring Data Repositories for advicing ?

注释：

@Retention(RetentionPolicy.RUNTIME) @Target(ElementType.METHOD) //@Inherited public @interface CustomerRequired { String value() default "customerrequired"; }

存储库：

public interface InvoiceRepository extends JpaRepository<Invoice,String>, QueryDslPredicateExecutor<Invoice> { @CustomerRequired public Page<Invoice> findAll(Predicate predicate, Pageable p); ... }

切入点和建议：

@Pointcut(value = "@target(customerRequired)",argNames = "customerRequired") public void targetCustomer(@SuppressWarnings("unused") CustomerRequired customerRequired) {/**/} @Before(value = "com.xxx.zzz.aop.logging.SystemArchitecture.targetCustomer(customerRequired) && com.xxx.zzz.aop.logging.SystemArchitecture.inDataLayer()") public void doAccessCheck(JoinPoint joinPoint, CustomerRequired customerRequired) { if (TransactionSynchronizationManager.isActualTransactionActive() && SecurityUtils.isAuthenticated()) { Session session = entitymanager.unwrap(Session.class); session.enableFilter("GLOBAL_FILTER").setParameter("customerId", SecurityUtils.getCurrentCustomerId()); } }

推荐答案

使用

@Pointcut("within(org.springframework.data.repository.CrudRepository)") public void inDATAExec(){}

使用如下

@Pointcut("this(org.springframework.data.repository.Repository)") public void inDATAExec(){}

它的作用是

any join point (method execution only in Spring AOP) where the proxy implements the Repository interface

你可以看一下 http：// docs .spring.io / spring / docs / current / spring-framework-reference / html / aop.html

希望有所帮助！
