Arquillian：执行此操作需要事务

Question

我正在尝试使用 arquillian- 运行我们的 JPA 单元测试，并嵌入一个 Wildfly。 到目前为止，当我对项目进行清理和构建时，我得到了以下步骤：

1. 嵌入的 wildfly 将部署在项目的 /target 文件夹中
2. MSSQL 数据库驱动程序将被部署并注册为驱动程序
3. arquillian 创建一个包含所有必需依赖项的 .war 文件
4. arquillian 将我项目的 .war 部署到嵌入式 wildfly 并开始对嵌入式 wildfly 进行单元测试

现在我的问题：当我在单元测试中调用 entitymanager 上的 .create() 或 .delete() 方法时，出现以下异常：

Caused by: javax.persistence.TransactionRequiredException: JBAS011469: Transaction is required to perform this operation (either use a transaction or extended persistence context)

这些是我的 pom.xml 的重要依赖项：

在我的 persistence.xml 中，我设置了 transaction-type="JTA"。

这是 .war 文件由 arquillian/shrinkwrap 创建的部分。 这东西用 Arquillian 的 @Deployment 标签注解：

PomEquippedResolveStage loadPomFromFile = Maven.resolver().loadPomFromFile("pom.xml");
        File[] asFile = loadPomFromFile.importRuntimeAndTestDependencies().resolve().withTransitivity().asFile();


        //MavenStrategyStage asFile = loadPomFromFile.importRuntimeAndTestDependencies().resolve();

        WebArchive webArchive = ShrinkWrap.create(WebArchive.class)
                .addAsLibraries(asFile)
                .addPackages(true, "de.companyXYZ")
                .addPackages(true, "org.springframework.beans.factory.config")
                // Adding persistence unit
                .addAsResource("test-persistence.xml", "META-INF/persistence.xml")
                // Add ms-sql driver for the embedded wildfly
                .addAsWebInfResource("wildfly-ds-driver.xml")
                // Add datasource for the embedded wildfly
                .addAsWebInfResource("wildfly-ds.xml")
                .addAsWebInfResource(EmptyAsset.INSTANCE, "beans.xml");

        webArchive.as(ZipExporter.class).exportTo(new File("./target/test-package.war"), true);

那么，有人可以帮我解决这个问题吗？ 我不明白为什么我会得到这个异常——因为野蝇应该做事务管理——这就是我对他的期望......

我添加，这解决了我的交易问题

import org.jboss.arquillian.transaction.api.annotation.Transactional;

    @Transactional
