我正在进行 JUnit 测试，我的堆栈跟踪中出现了我无法理解的错误。我也不确定我用于 OpenEJB 和 Hibernate 的版本。
我的 JUnit：
public class UsersDaoTest {
@EJB
private UsersDao usersDao;
@Test
public void testPersist() {
UsersBean usersBean = TrialUtil.generateUser(usersDao, "one", "john", "password", "john", "smith", "james");
assertNotNull(usersBean);
}
@Test
public void testIsUserRegistered() {
TrialUtil.generateUser(usersDao, "one", "john", "password", "john", "smith", "james");
assertNotNull(usersDao.isUserRegistered("john", "password"));
}
private static EJBContainer container;
@BeforeClass
public static void start() {
container = TrialUtil.createContainer();
}
@Before
public void inject() throws NamingException {
container.getContext().bind("inject", this);
}
@AfterClass
public static void stop() {
container.close();
} }
虽然这是我的 TrialUtil 课程：
public class TrialtUtil {
public static UsersBean generateUser(UsersDao usersDao,
String userId, String username, String password, String firstName,
String lastName, String middleName) {
UsersBean usersBean = new UsersBean();
usersBean .setUserId(userId);
usersBean .setUsername(username);
usersBean .setPassword(password);
usersBean .setFirstName(firstName);
usersBean .setLastName(lastName);
usersBean .setMiddleName(middleName);
usersDao .makePersistent(usersBean);
return usersBean;
}
public static EJBContainer createContainer() {
// TODO Auto-generated method stub
final Properties p = new Properties();
// HSQL
p.put("SampleDataSource", "new://Resource?type=DataSource");
p.put("SampleDataSource.JdbcDriver", "org.hsqldb.jdbcDriver");
p.put("SampleDataSource.JdbcUrl", "jdbc:hsqldb:mem:mem:aname");
p.put("SampleDataSource.UserName", "sa");
return EJBContainer.createEJBContainer(p);
} }
持久性.xml：
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">

<properties>
<property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect" />
<property name="hibernate.hbm2ddl.auto" value="create" />

</persistence-unit>
所以这是我的堆栈跟踪（对不起，我无法正确格式化。）：

所以 NullPointerException 指向 TrialUtil 类container.close();。我已经阅读了这个和这个，但我不太确定我在 Eclipse(JavaEE) 中使用的是什么版本。如果有人知道这些错误，请帮助。谢谢你。
