java.lang.IllegalStateException : Unable to retrieve EntityManagerFactory for unitName HorizonPU with Arquillian 错误

Question

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，如下所示:

<?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">
        <jta-data-source>jdbc/horizonBase</jta-data-source>
        <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:

testarchive.war:
/WEB-INF/
/WEB-INF/classes/
/WEB-INF/classes/com/
/WEB-INF/classes/com/macraeanddick/
/WEB-INF/classes/com/macraeanddick/marketinghorizon/

/WEB-INF/classes/com/macraeanddick/marketinghorizon/company/Budget.class

/WEB-INF/classes/com/macraeanddick/marketinghorizon/company/BudgetLine.class
/WEB-INF/classes/com/macraeanddick/facades/
/WEB-INF/classes/com/macraeanddick/facades/BudgetFacade.class
/META-INF/
/META-INF/beans.xml
/META-INF/persistence.xml

我认为一切正常，POM如下:

但是如果我运行测试，我会得到以下信息:

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!

我终于弄清楚了这个问题。如果你正在部署一个网络应用程序，那么 persistence.xml 文件需要放在 WEB-INF/classes/META-INF/中，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。
