我是 Java EE 6 的新手，我正在尝试开发非常简单的 JAX-RS 应用程序。 RESTfull Web 服务工作正常。但是，当我运行测试应用程序时，我得到了以下结果。我做错了什么？或者我忘记了任何配置？当然，我正在创建一个 JNDI 并且正在使用 Netbeans 6.8 IDE。最后，感谢您的建议。
我的实体:

Exception Description: Cannot acquire data source [BookstoreJNDI].

最佳答案
首先，您的类路径中缺少一些 JAR，我的建议是添加 $GF_HOME/modules/gf-client.jar (不要将 JAR 复制到您的项目中，直接指向它)。
其次，您的测试在当前状态下不会通过，它缺少一些部分:
persist需要在事务内调用- 您需要
刷新更改才能获得分配的 ID。
这是一个改进的版本，它将使用自己的 EntityManager 并在事务内运行每个测试方法(在测试方法结束时回滚):
public class BookTest {
private static EntityManager em;
private static EntityManagerFactory emf;
@BeforeClass
public static void createEntityManagerFactory() {
emf = Persistence.createEntityManagerFactory("E01R01PU");
}
@AfterClass
public static void closeEntityManagerFactory() throws Exception {
emf.close();
}
@Before
public void beginTransaction() {
em = emf.createEntityManager();
em.getTransaction().begin();
}
@After
public void rollbackTransaction() {
if (em.getTransaction().isActive()) {
em.getTransaction().rollback();
}
if (em.isOpen()) {
em.close();
}
}
@Test
public void createBook() {
Book book = new Book();
book.setId(1);
book.setDescription("Mastering the Behavior Driven Development with " +
"Ruby on Rails");
book.setTitle("Mastering the BDD");
book.setPrice(25.9f);
book.setNumberofpage(1029);
em.persist(book);
em.flush(); // sync the in-memory changes with the db
// now this will pass
assertNotNull("ID should not be null", book.getId());
}
}
奖励:此测试将通过:)
请注意，人们通常更喜欢能够运行测试而无需启动容器，即不依赖 JNDI。以下 persistence.xml 展示了如何配置 EclipseLink 以连接到在服务器模式下运行的 Derby 数据库，您可以在测试上下文中使用该数据库:
