Spring Boot实体基于AOP扩展元数据方案失效问题求助

我有一个Spring Boot 2.7.6应用，部分实体由Mongo仓库管理，想要为实体扩展元数据。计划构建元数据仓库存储所有实体的元数据，让实体实现带默认方法的IMetadata接口，通过切面从元数据仓库加载数据并返回。

代码结构 #

IMetadata接口 #

package io.zzzz.interfaces;
//imports are there

public interface IMetadata {
  @JsonIgnore
  default List<Metadata> getMetadata() {
    return null;
  }
}

SampleEntity实体类 #

package io.zzzz.entities;
//imports are there

@Getter
@Setter
@NoArgsConstructor
@Configurable
@Document("samples")
public class SampleEntity implements IMetadata {
  @Id private String id;
  // ... many other fields
}

MetadataAspect切面类 #

package io.zzzz;
//imports are there

@Aspect
@Component
@EnableAspectJAutoProxy(proxyTargetClass=true)
@Slf4j
public class MetadataAspect implements ApplicationContextAware {
  @Override
  public void setApplicationContext(ApplicationContext context) throws BeansException {
    metadataService = context.getBean(MetadataService.class);
  }

  @Around("execution(* getMetadata(..))")
  public Object getMetadataAdvice(ProceedingJoinPoint joinPoint) {
    log.debug("Accessing metadata ...");
    var metadataOwner = joinPoint.getTarget();
    var md = metadataService.getMetadataForEntity((IMetadata) metadataOwner);
    log.debug("Accessed metadata.");
    return md;
  }
}

已添加的依赖 #

<dependency>
  <groupId>org.springframework</groupId>
  <artifactId>spring-instrument</artifactId>
  <version>5.3.24</version>
  <scope>runtime</scope>
</dependency>
<dependency>
  <groupId>org.springframework.boot</groupId>

</dependency>
<dependency>
  <groupId>org.aspectj</groupId>
  <artifactId>aspectjrt</artifactId>
  <version>1.9.7</version>
</dependency>

配置操作 #

• 已在应用中添加@EnableLoadTimeWeaving注解
• 配置VM参数：-javaagent:<path>/spring-instrument-5.3.24.jar
• 因方案未生效，在META-INF下创建aop.xml：

<aspectj>
  <weaver>
    <include within="io.zzzz.entities..*"/>
  </weaver>
  <aspects>
    <aspect name="io.zzzz.MetadataAspect"/>
  </aspects>
</aspectj>

当前问题 #

添加VM参数-Daj.weaving.verbose=true后能看到织入操作，通用切面可以拦截服务方法，但getMetadata方法始终未被拦截，不知道如何解决，怀疑该方案不可行。
