在嵌入式 TomEE 8.0 中使用带有 OpenJPA 的实体管理器时出现神秘 "org.apache.openjpa.persistence.PersistenceException: null" 异常
Getting cryptic "org.apache.openjpa.persistence.PersistenceException: null" exception when using entity manager with OpenJPA in embedded TomEE 8.0
我正在尝试为使用 Apache TomEE Maven 插件开发的 Java 企业 Web 应用程序编写测试。该应用程序工作正常，一切似乎都正常运行。我考虑过将 JUnit Jupiter 5 和 EJBContainer API 与嵌入式 TomEE 8.0.0 一起使用（我对 TomEE Maven 插件使用相同的版本）。但是，在我 bootstrap 嵌入式容器之后，一旦调用使用实体管理器的方法，就会启动一个非常混乱的异常。下面是异常，以及嵌入式容器在抛出之前记录的一些信息。

This means that your application will be less efficient than it would if you ran the OpenJPA enhancer.

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没有出现：
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.
下一行也是如此，它没有包含在上一个块中：
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，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），一切似乎都运行良好......直到它不工作. Criteria API 用于在应用程序中编写查询，其中一些使用 JOIN 子句和 GROUP BY，并且由于一些严重的错误，EclipseLink 在制定 JPQL 等效查询时简单地忽略了 GROUP BY。我试图通过在纯 JPQL 中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，导致应用程序在 运行 在非测试环境中。但这与主要问题并没有真正的关系，所以让我们继续。
下面是我的测试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.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（测试数据库在内存中，主要的数据库是基于文件的，尽管因为我使用的是 TomEE Maven 插件，所以没有太大的实际区别。
请注意，在使用 PersistenceContext 注释在整个应用程序中注入实体管理器时，我没有指定 unitName 元素以确保根据天气测试使用正确的持久性单元正在 运行 与否；不会出现歧义，因为 persistence.xml 和 test.persistence.xml 都只定义了一个持久化单元，所以容器会自动选择合适的持久化单元（当 运行 测试时，主要资源文件被忽略，有利于测试的）。
如前所述，一旦调用实体管理器方法（甚至 entityManager.getProperties()）就会抛出异常。在测试中，调用了方法userAgent.createUser(user)，看起来像这样：
public void createUser(@NotNull final User user) {
this.entityManager.persist(user);
}
最后，我通过调整提供的说明解决了问题 here。
准确地说，我将以下块添加到 POM 文件的 plugins 部分。
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>3.0.0-M4</version>

如果您在这里 运行 遇到相同的问题，请确保 openejb-javaagent 工件的版本与 <argline> 标签中指定的版本相匹配（8.0.0在这种情况下）。
我正在尝试为使用 Apache TomEE Maven 插件开发的 Java 企业 Web 应用程序编写测试。该应用程序工作正常，一切似乎都正常运行。我考虑过将 JUnit Jupiter 5 和 EJBContainer API 与嵌入式 TomEE 8.0.0 一起使用（我对 TomEE Maven 插件使用相同的版本）。但是，在我 bootstrap 嵌入式容器之后，一旦调用使用实体管理器的方法，就会启动一个非常混乱的异常。下面是异常，以及嵌入式容器在抛出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没有出现：
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.
下一行也是如此，它没有包含在上一个块中：
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，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），一切似乎都运行良好......直到它不工作. Criteria API 用于在应用程序中编写查询，其中一些使用 JOIN 子句和 GROUP BY，并且由于一些严重的错误，EclipseLink 在制定 JPQL 等效查询时简单地忽略了 GROUP BY。我试图通过在纯 JPQL 中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，导致应用程序在 运行 在非测试环境中。但这与主要问题并没有真正的关系，所以让我们继续。
下面是我的测试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（测试数据库在内存中，主要的数据库是基于文件的，尽管因为我使用的是 TomEE Maven 插件，所以没有太大的实际区别。
请注意，在使用 PersistenceContext 注释在整个应用程序中注入实体管理器时，我没有指定 unitName 元素以确保根据天气测试使用正确的持久性单元正在 运行 与否；不会出现歧义，因为 persistence.xml 和 test.persistence.xml 都只定义了一个持久化单元，所以容器会自动选择合适的持久化单元（当 运行 测试时，主要资源文件被忽略，有利于测试的）。
如前所述，一旦调用实体管理器方法（甚至 entityManager.getProperties()）就会抛出异常。在测试中，调用了方法userAgent.createUser(user)，看起来像这样：
public void createUser(@NotNull final User user) {
this.entityManager.persist(user);
}
最后，我通过调整提供的说明解决了问题 here。
准确地说，我将以下块添加到 POM 文件的 plugins 部分。
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>3.0.0-M4</version>
