java.lang.IllegalStateException：无法使用 Arquillian 检索 unitName HorizonPU 的 EntityManagerFactory
java.lang.IllegalStateException: Unable to retrieve EntityManagerFactory for unitName HorizonPU with Arquillian
我希望有人能帮助我解决一个非常令人沮丧的问题。
我想使用 Arquillian 来测试我正在开发的 Web 应用程序，但我很难尝试让 JPA 测试达到 运行。我是 Arquillian 的新手，我必须承认我发现它使用起来非常棘手。
我的测试用例如下：
@RunWith(Arquillian.class)
public class BudgetFacadeTest
{
@Deployment
public static WebArchive deploy(){
WebArchive archive = ShrinkWrap.create(WebArchive.class, "testarchive.war")
.addClasses(Budget.class, BudgetLine.class, BudgetSection.class, BudgetFacade.class)
.addAsManifestResource("META-INF/persistence.xml", "persistence.xml")
.addAsManifestResource(EmptyAsset.INSTANCE, "beans.xml");
System.out.println(archive.toString(true));
return archive;
}
@EJB
BudgetFacade instance;
@Test
public void testArquillianWorking(){
instance.count();
}
}
这很简单。持久化单元在单独的测试文件夹中，如下：
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">
<persistence-unit name="HorizonPU" transaction-type="JTA">

<exclude-unlisted-classes>false</exclude-unlisted-classes>
<properties>
<property name="javax.persistence.schema-generation.database.action" value="drop-and-create"/>
<property name="eclipselink.logging.level.sql" value="FINE"/>
<property name="eclipselink.logging.parameters" value="true"/>
</properties>
</persistence-unit>
</persistence>
压缩包结构如下：

我完全不知道我做错了什么并且已经在这上面浪费了一天的时间。任何建议将不胜感激！
我终于弄清了这一点。如果你正在部署一个网络应用程序，那么 persistence.xml 文件需要进入 WEB-INF/classes/META-INF/，换句话说，META-INF 不应该在存档的顶层。通常，Arquillian 的文档并不清楚如何实现这一点，但我的问题的解决方案是将测试中的部署方法更改为：
WebArchive archive = ShrinkWrap.create(WebArchive.class, "testarchive.war")
.addClasses(Budget.class, BudgetLine.class, BudgetSection.class, BudgetFacade.class)
.addAsResource("META-INF/persistence.xml")
.addAsWebInfResource(EmptyAsset.INSTANCE, "beans.xml");
请注意 persistence.xml 现在添加了 .addAsResource，beans.xml 添加为 .addAsWebInfResource。
