根据生产或测试环境，在Eclipse中使用不同的JPA.persistence.xml [英] Use different JPA.persistence.xml in Eclipse depending on production or test environment

问题描述

我们正在与gradle合作，并拥有默认的项目结构：

We are working with gradle and have the default project structure:

/src
   /main
     /java
     /resources
       /META-INF
         persistence.xml
   /test
     /java
     /resources
       /META-INF
         persistence.xml

虽然我们用gradle运行我们的junit测试，一切都很好没有关于源路径等的特殊的gradle配置）：使用'test'的persistence.xml。

While we run our junit tests with gradle, all is fine (we do not have any special gradle configuration concerning source paths or the like): the persistence.xml from 'test' is used.

但是，如果我们尝试运行我们的junit测试使用eclipse，始终使用'main'的peristence.xml。

But if we try to run our junit tests with eclipse, always the peristence.xml from 'main' is used.

我们如何配置eclipse以使用main的persistence.xml作为一个启动配置，但是对于所有junit测试，test的persistence.xml是

How can we configure eclipse to use the persistence.xml from 'main' for one launch configuration, but the persistence.xml from 'test' for all junit tests?

推荐答案

关于从类路径加载的资源：

Another thing to try, if this is a general problem about resources loaded from your classpath:

在Ec中lipse的项目属性Java Build Path-> Order and Export将您的测试文件夹放在src文件夹的上方。

In Eclipse's project properties, Java Build Path->Order and Export, put your test folder above your src folder.

然后在部署程序集下排除您的测试文件夹

Then under Deployment Assembly, exclude your test folder

这将确保在Eclipse中直接启动测试时，您将首先搜索测试文件夹的classpath资源。但是当您作为webapp启动时，测试文件夹将从 WEB-INF / classes 中排除。

That will ensure that when you launch tests directly from within Eclipse, you will search the test folder first for classpath resources. But when you launch as a webapp instead, the test folders would be excluded from WEB-INF/classes.
