Spring Boot Load orm.xml [英] Spring Boot Load orm.xml

问题描述

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?

I want to externalize my custom mappings for Jpa to an XML file. I've seen examples of using orm.xml however when I create orm.xml in resources/META-INF it does not appear to be loaded. All the examples I've seen it gets loaded through persistence.xml, which I don't have with Spring Boot. I didn't turn up much searching for answers. How do I make Spring Boot load my orm.xml file?

orm.xml示例

推荐答案

好的错误警报，默认情况下，Spring Boot会加载它，但是我的Intellij/Gradle设置存在另一个问题，即未部署最新版本/WAR因此它在没有orm.xml的情况下进行了部署.我必须进行gradle清理，并使Intellij中的缓存无效并重新启动.

Okay false alarm, it appears Spring Boot loads it by default, however my Intellij / Gradle setup had another issue, where it was not deploying the latest build / WAR so it deployed without the orm.xml. I had to do a gradle clean, and invalidate the cache in Intellij and restart.
