Maven的测试过程中的persistence.xml未找到 [英] persistence.xml not found during maven testing

问题描述

我想一个Maven构建进行集成测试过程中，测试数据加载到测试数据库。 persistence.xml中被复制到目标/测试类/ META-INF / 正确的，但我得到的时候测试运行此异常。

I'm trying to load test data into a test DB during a maven build for integration testing. persistence.xml is being copied to target/test-classes/META-INF/ correctly, but I get this exception when the test is run.

javax.persistence.PersistenceException：
  没有持久性提供
  EntityManager的一个名为aimDatabase

javax.persistence.PersistenceException: No Persistence provider for EntityManager named aimDatabase

这看起来像是没有找到或装载的persistence.xml。

It looks like it's not finding or loading persistence.xml.

推荐答案

只是一个基于Maven的/ Eclipse的JPA项目解决了同样的问题。

Just solved the same problem with a Maven/Eclipse based JPA project.

我有我的META-INF目录下的的src / main / JAVA 与concequence，它没有在测试阶段之前复制到目标目录。

I had my META-INF directory under src/main/java with the concequence that it was not copied to the target directory before the test phase.

这个目录移动到的src / main /资源解决了这个问题，并确保了 META-INF / persistence.xml中文件是目标/班present 当测试运行。

Moving this directory to src/main/resources solved the problem and ensured that the META-INF/persistence.xml file was present in target/classes when the tests were run.

我的认为的是，JPA面把我的 META-INF / persistence.xml中文件中的的src / main / java的，这竟然是我的问题的根源。

I think that the JPA facet put my META-INF/persistence.xml file in src/main/java, which turned out to be the root of my problem.
