Spring Boot Load orm.xml

Question

我想将Jpa的自定义映射外部化为XML文件。我已经看到了使用orm.xml的示例，但是当我在resources / META-
INF中创建orm.xml时，似乎没有被加载。我看到的所有示例都是通过persistence.xml加载的，而Spring
Boot却没有。我没有太多寻找答案。如何使Spring Boot加载orm.xml文件？

示例orm.xml

Answer 1

好的错误警报是，Spring Boot默认情况下会加载它，但是我的Intellij / Gradle设置还有另一个问题，即它没有部署最新的build /
WAR，因此没有orm.xml进行了部署。我必须进行gradle清理，并使Intellij中的缓存无效并重新启动。
