    我希望有人能帮我解决一个非常令人沮丧的问题。

    我想用Arquillian测试我正在开发的一个Web应用程序,我很难让JPA测试运行。我对Arquillian很陌生,我必须承认,我发现它很难使用。

    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。持久性单元位于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>

    收缩存档结构如下: 

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

    我认为这一切都很正常,POM如下:

        <testResource>
            <directory>src/test/resources-glassfish-embedded</directory>
        </testResource>
    </testResources>

    但如果我运行测试,我会得到以下结果:

    我完全不知道我做错了什么,已经为此浪费了一天。任何建议都将不胜感激!

    我终于找到了这件事的真相。如果您正在部署web应用程序,那么persistence.xml文件需要位于web-INF/classes/META-INF/中,换句话说,META-INF不应该位于归档的顶层。通常,Arquillian的文档并不十分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");

    注意,persistence.xml现在添加了 .addAsResource ,beans.xml添加为 .addAsWebInfResource .
