Spring 批处理 - 由以下原因引起：org.hibernate.hql.internal.ast.QuerySyntaxException：未映射
Spring Batch - Caused by: org.hibernate.hql.internal.ast.QuerySyntaxException: is not mapped
我希望使用 Spring Boot v2.2.6.RELEASE + Batch 示例将 Oracle 数据加载到 Postgres 中。在此示例中，我分别为 Oracle 和 Postgres 创建了两个数据源。
我使用了 JpaPagingItemReader，它通过执行 JPQL 读取 Oracle Table 并将数据加载到 Postgres。 JpaPagingItemReader 尝试进行查询时，出现以下错误。
错误：

嗯，你的潜在错误是：
Caused by: org.hibernate.hql.internal.ast.QuerySyntaxException: LifeCycleStatusEntity is not mapped
这意味着您没有将 LifeCycleStatusEntity 映射为 @Entity，或者您的 ApplicationContext 或 EntityManagerFactory/SessionFactory 设置不正确。没有更多信息很难判断。
我希望使用 Spring Boot v2.2.6.RELEASE + Batch 示例将 Oracle 数据加载到 Postgres 中。在此示例中，我分别为 Oracle 和 Postgres 创建了两个数据源。
我使用了 JpaPagingItemReader，它通过执行 JPQL 读取 Oracle Table 并将数据加载到 Postgres。 JpaPagingItemReader 尝试进行查询时，出现以下错误。

嗯，你的潜在错误是：
Caused by: org.hibernate.hql.internal.ast.QuerySyntaxException: LifeCycleStatusEntity is not mapped
这意味着您没有将 LifeCycleStatusEntity 映射为 @Entity，或者您的 ApplicationContext 或 EntityManagerFactory/SessionFactory 设置不正确。没有更多信息很难判断。
