Question

在Jhipster中使用Javers时出现此错误。我使用了Spring Boot的配置：

javers:
  mappingStyle: FIELD
  algorithm: SIMPLE
  commitIdGenerator: synchronized_sequence
  prettyPrint: true
  typeSafeValues: false
  newObjectSnapshot: false
  packagesToScan:
  auditableAspectEnabled: true
  springDataAuditableRepositoryAspectEnabled: true
  sqlSchema:
  sqlSchemaManagementEnabled: true
  sqlGlobalIdCacheDisabled: false
  objectAccessHook: org.javers.hibernate.integration.HibernateUnproxyObjectAccessHook
  prettyPrintDateFormats:
    localDateTime: 'dd MMM yyyy, HH:mm:ss'
    zonedDateTime: 'dd MMM yyyy, HH:mm:ssZ'
    localDate: 'dd MMM yyyy'
    localTime: 'HH:mm:ss'

public Object getIdOf(Object instance) {
        Validate.argumentIsNotNull(instance);
        if (!this.isInstance(instance)) {
            throw new JaversException(JaversExceptionCode.NOT_INSTANCE_OF, new Object[]{this.getName(), this.getBaseJavaClass().getName(), instance.getClass().getName()});
        } else if (this.hasCompositeId()) {
            Map compositeId = Collections.unmodifiableMap((Map)this.idProperties.stream().filter((p) -> {
                return p.get(instance) != null;
            }).collect(Collectors.toMap((p) -> {
                return p.getName();
            }, (p) -> {
                return p.get(instance);
            })));
            if (compositeId.isEmpty()) {
                throw new JaversException(JaversExceptionCode.ENTITY_INSTANCE_WITH_NULL_COMPOSITE_ID, new Object[]{this.getName(), this.getIdPropertyNames()});
            } else {
                return Collections.unmodifiableMap(compositeId);
            }
        } else {
            Object cdoId = this.getIdProperty().get(instance);
            if (cdoId == null) {
                throw new JaversException(JaversExceptionCode.ENTITY_INSTANCE_WITH_NULL_ID, new Object[]{this.getName(), this.getIdProperty().getName()});
            } else {
                return cdoId;
            }
        }
    }

public boolean isInstance(Object cdo) {
        Validate.argumentIsNotNull(cdo);
        return this.baseJavaClass.isAssignableFrom(cdo.getClass());
    }

当我尝试修改实体时，

Javers引发了 JaversExceptionCode.NOT_INSTANCE_OF 异常。

错误消息是：

Can't create InstanceId for EntityType 'Objective', class 'com.project.domain.Objective' bounded to EntityType is not assignable from given class 'com.project.domain.Objective'

此错误仅在我停止/启动应用程序时发生。但这不是定期发生的。我不知道Javers中是否有任何缓存。我们需要在每次重新启动应用程序时清除此问题。

实际上，我无法提供隔离该错误的测试用例，因为它与项目的模型映射有关。它还需要创建Jhipster上下文来重现该错误。然后让我在这里提出问题。我希望有人遇到类似的问题。

org.javers.common.exception.JaversException：NOT_INSTANCE_OF：无法为EntityType
