java - 在嵌入式 TomEE 8.0 中使用带有 OpenJPA 的实体管理器时出现神秘的 "org.apache.openjpa.persistence.PersistenceException: null"异常

我试图为使用 Apache TomEE Maven 插件开发的 Java Enterprise Web 应用程序编写测试。该应用程序运行良好，一切似乎都正常运行。我考虑使用 JUnit Jupiter 5 和带有嵌入式 TomEE 8.0.0 的 EJBContainer API(我对 TomEE Maven 插件使用相同版本)。然而，在我引导嵌入式容器之后，一旦调用使用实体管理器的方法，就会启动一个非常令人困惑的异常。下面是异常，以及嵌入式容器在抛出异常之前记录的一些信息。

值得注意的是，嵌入式容器记录了以下行，当我使用 TomEE Maven 插件正常启动应用程序时，该行不会出现:

INFO: Creating subclass and redefining methods for "[class application.entities.User, class application.entities.Vote, class application.entities.Report, class application.entities.BacklogEntry, class application.entities.Review]". This means that your application will be less efficient than it would if you ran the OpenJPA enhancer.

下面的行也是如此，它没有包含在前一个 block 中:

INFO: JAVA AGENT NOT INSTALLED. The JPA Persistence Provider requested installation of a ClassFileTransformer which requires a JavaAgent.  See http://tomee.apache.org/javaagent.html

我尝试按照 URL http://tomee.apache.org/javaagent.html 提供的说明进行操作，这很可能会解决问题，但这些似乎已经过时了，最终我无法让它们工作。

然后我将用于测试的持久性提供程序从默认的 OpenJPA 3.1.0 切换到 EclipseLink 2.7.5(当前最新版本)，一切似乎都工作正常......直到它不起作用。 Criteria API 用于在应用程序中编写查询，其中一些查询使用 JOIN 子句和 GROUP BY，并且由于一些令人讨厌的错误，EclipseLink 在制定 JPQL 等效查询时只是忽略 GROUP BY。我试图通过用普通 JPQL 编写这些查询来临时解决这个问题，但其中一些查询在 ORDER BY 子句中使用 COALESCE 函数，你知道什么...... OpenJPA 不支持这，导致应用程序在运行时抛出错误在非测试环境中。但这与主要问题并不真正相关，所以让我们继续。

这是我的测试类(class):

public class UsersAgentTest {

    private static EJBContainer container;

    @BeforeAll
    public static void initializeContainer() {
        Properties properties = new Properties();
        properties.put("openejb.altdd.prefix", "test");
        container = EJBContainer.createEJBContainer(properties);
    }

    @AfterAll
    public static void stopContainer() {
        if (container != null)
            container.close();
    }

    @Test
    public void test() throws NamingException {
        Context context = container.getContext();
        UsersAgent usersAgent = (UsersAgent) context.lookup("java:global/soundrate/UsersAgent");
        User user = new User()
                .setUsername("test_user")
                .setEmail("user@test.org")
                .setPassword("password123")
                .setSignUpDate(new Date())
                .setRole(User.Role.USER);
        usersAgent.createUser(user);
        Assertions.assertNotNull(usersAgent.getUser("test_user"));
    }

}

这些是 test.persistence.xml 和 test.resources.xml 文件:

<persistence 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"
             version="2.1">
    <persistence-unit name="soundrateTestPersistenceUnit" transaction-type="JTA">
        <jta-data-source>jdbc/soundrateTestDataSource</jta-data-source>
        <properties>
            <property name="javax.persistence.schema-generation.database.action"
                      value="drop-and-create"/>
        </properties>
    </persistence-unit>
</persistence>

<resources>
    <Resource id="jdbc/soundrateTestDataSource" type="javax.sql.DataSource">
        JdbcDriver = org.hsqldb.jdbcDriver
        JdbcUrl = jdbc:hsqldb:mem:soundrate
    </Resource>
</resources>

persistence.xml 和 resources.xml 文件几乎相同，唯一的区别是数据源和持久性单元名称以及 JDBC URL(测试数据库位于内存中，主要数据库是基于文件的，尽管由于我使用的是 TomEE Maven 插件，因此没有太大的实际差异)。

请注意，当使用 PersistenceContext 注释在整个应用程序中注入(inject)实体管理器时，我没有指定 unitName 元素来确保使用正确的持久性单元取决于是否正在运行测试；不会出现任何歧义，因为 persistence.xml 和 test.persistence.xml 都只定义了一个持久单元，因此容器会自动选择正确的一个(当运行测试时主要资源文件将被忽略，以支持测试文件)。

如前所述，一旦调用实体管理器方法(甚至entityManager.getProperties())，就会引发异常。在测试中，调用了userAgent.createUser(user)方法，如下所示:

public void createUser(@NotNull final User user) {
    this.entityManager.persist(user);
}

最佳答案

最后，我通过调整提供的说明解决了这个问题here 。准确地说，我将以下 block 添加到 plugins POM 文件中的部分。

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>3.0.0-M4</version>
    <configuration>
        <forkCount>1</forkCount>
        <reuseForks>false</reuseForks>
        <argLine>-javaagent:"${project.build.directory}/openejb-javaagent-8.0.0.jar"</argLine>
        <workingDirectory>${project.build.directory}</workingDirectory>
    </configuration>
</plugin>
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-dependency-plugin</artifactId>

    <executions>
        <execution>
            <id>copy</id>
            <phase>process-resources</phase>
            <goals>
                 <goal>copy</goal>
            </goals>
            <configuration>
                <artifactItems>
                    <artifactItem>
                        <groupId>org.apache.tomee</groupId>
                        <artifactId>openejb-javaagent</artifactId>
                        <version>8.0.0</version>
                        <outputDirectory>${project.build.directory}</outputDirectory>
                    </artifactItem>
                </artifactItems>
            </configuration>
        </execution>
    </executions>
</plugin>

如果您在这里遇到同样的问题，请确保 openejb-javaagent 的版本工件与 <argline> 中指定的工件匹配标签(在本例中为 8.0.0)。
