启用S​​pring AOP后，Spring数据存储库不起作用[JAVA 11]

标签： spring spring-data-jpa spring-aop java-11

嗨，我有一个使用Spring 5，Spring Data，Spring AOP和Java 11的应用程序（我也使用JAVA 9模块系统）。 我的spring-context / spring-aspects版本是5.1.2。 Spring Data版本是2.1.2.RELEASE 这两个版本都是最新的。 我以以下方式创建存储库：

@Repository
public interface AirportRepository extends JpaRepository<Airport, Long> {
}

我已使用

启用了Spring数据存储库 
@Configuration
@EnableTransactionManagement
@PropertySource("classpath:persistence-jndi.properties")
@PropertySource("classpath:hibernate.properties")
@EnableJpaRepositories(basePackages = "com.xx.yy.persistence")
public class PersistenceJNDIConfig {
  //Datasource configs
}

在使用以下配置引入Spring AOP之前，它一直运行良好。 

@ComponentScan(basePackages = "com.xx.yy")
@EnableAspectJAutoProxy(exposeProxy = true)
public class AdminServicesConfiguration {
}

和

@Aspect
@Component
public class DasErrorHandler {

    @Around("@target(com.xx.yy.commons.aop.ErrorManagedDAS)")
    public Object handle(ProceedingJoinPoint proceedingJoinPoint){
        //Some code
    }
}

但是现在在服务器启动时，出现以下错误：

Caused by: java.lang.IllegalStateException: Cannot convert value of type 'com.sun.proxy.$Proxy82 implementing org.springframework.data.util.Streamable,org.springframework.aop.SpringProxy,org.springframework.aop.framework.Advised,org.springframework.core.DecoratingProxy' to required type 'org.springframework.data.repository.core.support.RepositoryComposition$RepositoryFragments' for property 'repositoryFragments': no matching editors or conversion strategy found

    at org.springframework.beans.AbstractNestablePropertyAccessor.convertIfNecessary(AbstractNestablePropertyAccessor.java:585)
    ... 103 more

似乎由Spring生成的代理类型不匹配，这导致了上述错误，我尝试通过以下方式强制Spring使用CGLIB代理：

@EnableAspectJAutoProxy(exposeProxy = true, proxyTargetClass = true )

然后，即使我的类路径上有SpringProxy类，错误也会变为以下错误。请帮助：

编辑：模块的module-info.java如下

module com.xx.yy.admin.services {
    //External
    requires spring.webmvc;
    requires spring.web;
    requires spring.context;
    requires javax.servlet.api;
    requires org.apache.commons.collections4;
    requires org.apache.logging.log4j;
    requires org.apache.logging.log4j.core;
    requires spring.aop;
    requires org.aspectj.weaver;
    requires spring.aspects;

    //Internal
    requires com.xx.yy.utils;
    requires com.xx.yy.persistence;
}

module com.xx.yy.persistence {
    requires spring.context;
    requires spring.beans;
    requires spring.core;
    requires spring.data.commons;
    requires spring.data.jpa;
    requires spring.tx;

尝试将AOP库添加到依赖项

x <- c(1,1,2,3,5)
n <- length(x)
res <- 5
unique(combn(c(x,rep(0,n-1)), n, function(x) x[x!=0][sum(x)==res], FALSE))[-1]
# [[1]]
# [1] 1 1 3
# 
# [[2]]
# [1] 2 3
# 
# [[3]]
# [1] 5
