在 maven-verify 中没有自动检测 JPA 实体 [英] No autodetection of JPA Entities in maven-verify

问题描述

如果我将 persistence.xml 放在 src/test/META-INF 文件夹中，则自动检测实体不适用于 maven-verify.当persistence.xml 位于src/main/META-INF 文件夹中时，它可以工作.

If I put the persistence.xml in the src/test/META-INF folder, autodetection the Entities does not work with maven-verify. When the persistence.xml is located in the src/main/META-INF folder it works.

在 Eclipse 中运行测试适用于两种情况.

Running the tests in eclipse works in both cases.

当persistence.xml 位于src/test 文件夹中时，有没有办法让自动检测为maven-verify 工作?

Is there a way to get autodetection to work for maven-verify when the persistence.xml is located in the src/test Folder?

持久性.xml:

<persistence xmlns="http://java.sun.com/xml/ns/persistence" version="1.0">

  <persistence-unit name="Unit" transaction-type="RESOURCE_LOCAL">
    <properties>
      <!-- Scan for annotated classes and Hibernate mapping XML files -->
      <property name="hibernate.archive.autodetection" value="class" />
    </properties>
  </persistence-unit>

</persistence>

推荐答案

默认情况下，自动检测适用于与 persistence.xml 位于同一类路径项中的实体.它可以通过 元素进行配置.

By default autodetection works for entities in the same classpath item as persistence.xml. It can be configured by <jar-file> elements.

要在 persistence.xml 在 src/test/resources/META-INF 中时启用正确的自动检测，我使用以下技巧:

To enable correct autodetection when persistence.xml is in src/test/resources/META-INF I use the following trick:

persistence.xml:

<persistence ...>
    <persistence-unit ...>
        <jar-file>${project.build.outputDirectory}</jar-file>
        ...
    </persistence-unit>
</persistence>

pom.xml - 为 src/test/resources 启用资源过滤:

pom.xml - enable resource filtering for src/test/resources:

<project ...>
    ...
    <build>
        <testResources>
            <testResource>
                <directory>src/test/resources</directory>
                <filtering>true</filtering>
            </testResource>
        </testResources>
    </build>
</project>

如果您的 persistence.xml 实际上在 src/test/META-INF 中，我不确定如何使用它.

Though I'm not sure how to use it if your persistence.xml is actually in src/test/META-INF.
