Spring 数据存储库的方面建议不起作用
Aspect Advice for Spring Data Repository doesnt work
我正在尝试为存储库创建一些切入点和之前的建议，以便在 Spring 数据 Spring Boot 中启用对某些存储库的 entitymanager 过滤。我在项目中也有 web 和服务层，AspectLogging 对两者都有效。但是我不能对存储库做同样的事情。我已经苦苦挣扎了 2 天，我尝试了很多方法来修复它。我几乎阅读了所有关于此的文档、问题和线程（代理问题 CGlib 和 JDK 代理等）。我使用 jhipster 创建项目。
我无法使用 CrudRepository 部署除 @Pointcut 之外的应用程序。甚至它部署的 @Before 也不会被 Repository 中的方法调用调用。我想我有一个类似的问题，就像下面的问题一样。 proxy confusion

有人知道它可能是什么吗？
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：
@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(){}
}
过滤方面：
@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有关。我试图更改存储库中自定义注释的切入点。它不适用于方法或 class 级别。我在以下链接中阅读了有关此的问题。

我为目标和注释苦苦挣扎了几个小时。但没有结果。
在 Spring 数据存储库中添加自定义注释真的不可能吗？
注解：
@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());
}
}
而不是使用
@Pointcut("within(org.springframework.data.repository.CrudRepository)")
public void inDATAExec(){}
像下面这样使用
@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
你可以看看http://docs.spring.io/spring/docs/current/spring-framework-reference/html/aop.html
希望对您有所帮助！
