启用Spring AOP后，Spring数据存储库无法工作[JAVA 11]
启用Spring AOP后，Spring数据存储库无法工作[JAVA 11]
提问于 2018-11-10 17:18:36
您好，我有一个使用Spring 5、Spring Data、Spring AOP和Java 11的应用程序(我也在使用JAVA 9模块系统)。我的-context/ Spring -aspects版本是5.1.2。aspects Data版本是2.1.2。aspects这两个版本都是最新的。我用以下方式创建了存储库：
@Repository
public interface AirportRepository extends JpaRepository<Airport, Long> {
}我已经使用以下命令启用了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
}在我引入Spring AOP之前，它一直工作得很好，使用下面的配置。
@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，我得到了以下错误：
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

... 103 moreSpring生成的代理类型似乎存在不匹配，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，即使我的类路径中有SpringProxy类，错误也会变为如下所示。请帮助：

尝试将AOP lib添加到依赖项中
<!-- https://mvnrepository.com/artifact/org.springframework/spring-aop -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-aop</artifactId>
<version>5.1.2.RELEASE</version>
