无法将 java.lang.Integer 字段 com.persistence.entity.CustomerOrderEntity.tenantId 设置为 java.lang.String

Question

每当我从 CustomerOrderEntity 中删除一对一关系时，我的下一个示例都会出现问题，我的测试没有问题通过，但是当我放回关系时，它失败告诉我不能将字符串分配给整数 我的代码有什么问题？ 我该如何解决？

    private CustomerOrderEntity order;
}

与下一个 Spring Boot 存储库

@Repository
public interface CustomerOrderEntityRepository extends JpaRepository<CustomerOrderEntity, String>, JpaSpecificationExecutor<CustomerOrderEntity> {

    @EntityGraph(CustomerOrderEntity.GRAPH_WITH_LINES)
    @Query("select entity from CustomerOrderEntity entity where entity.tenantId = :#{#param.tenantId} and entity.fulfilLocationId = :#{#param.fulfilLocationId} and entity.fulfilOrderId = :#{#param.fulfilOrderId}")
    Optional<CustomerOrderEntity> findOneByOrderIdWithLines(CustomerOrderEntity param);

    @EntityGraph(CustomerOrderEntity.GRAPH_WITH_DELIVERY)
    @Query("select entity from CustomerOrderEntity entity where entity.tenantId = :#{#param.tenantId} and entity.fulfilLocationId = :#{#param.fulfilLocationId} and entity.fulfilOrderId = :#{#param.fulfilOrderId}")
    Optional<CustomerOrderEntity> findOneByOrderIdWithDelivery(CustomerOrderEntity param);

    @EntityGraph(CustomerOrderEntity.GRAPH_WITH_ALL_PROPS)
    @Query("select entity from CustomerOrderEntity entity where entity.tenantId = :#{#param.tenantId} and entity.fulfilLocationId = :#{#param.fulfilLocationId} and entity.fulfilOrderId = :#{#param.fulfilOrderId}")
    Optional<CustomerOrderEntity> findOneByOrderIdWithAllProps(CustomerOrderEntity param);

}

以及下一个测试：

TestCase

当我尝试从存储库中检索 CustomerOrderEntity 时，它会给出下一个错误跟踪：

Answer 1

我认为您需要为域对象的属性添加 getter 和 setter。您可以首先为 CustomerOrderEntity.tenantId 添加一个 getter 和一个 setter，看看当您尝试重现此问题时是否会改变行为。
