我正在尝试创建EJB3.0容器管理的持久性bean,并且在连接到单元测试使用的内存中HSQLDB时遇到问题。我正在使用OpenEJB来实现我的独立容器实现。
我在持久性XML中有以下内容。
<persistence-unit name="wyvern-unit-test">
<description>In-memory HSQLDB database persistence unit used for unit testing.</description>
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<class>com.acme.test.model.LogEntry</class>
<class>com.acme.test.modell.Addressee</class>
<properties>
<property name="hibernate.connection.driver_class" value="org.hsqldb.jdbcDriver"/>
<property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/>
<property name="hibernate.connection.url" value="jdbc:hsqldb:mem:db"/>
<property name="hibernate.connection.username" value="sa"/>
<property name="hibernate.connection.password" value=""/>
<property name="hibernate.hbm2ddl.auto" value="create-drop"/>
</properties>
</persistence-unit>
这是我的服务bean:
@Stateless
public class LogEntryServiceBean implements LogEntryService {
@PersistenceContext
private EntityManager entityManager;
@Override
public LogEntry find(String uuid) {
return entityManager.find(LogEntry.class, uuid);
}
@Override
public void save(LogEntry logEntry) {
entityManager.merge(logEntry);
}
@Override
public void remove(LogEntry logEntry) {
entityManager.remove(entityManager.merge(logEntry)); // NOTE: [MF] Using "seek and destroy" pattern.
}
}
这是我的单元测试:
public class LogEntryServiceBeanTest {
private static Context context;
@BeforeClass
public static void beforeClass() {
context = EJBContainer.createEJBContainer().getContext();
}
@AfterClass
public static void afterClass() throws NamingException {
context.close();
}
@Test
public void createLogEntryTest() throws NamingException {
LogEntryService logEntryService = (LogEntryService) context.lookup("java:global/classes/LogEntryServiceBean");
LogEntry logEntry = new LogEntry();
Addressee addressee = new Addressee();
logEntry.setSummary("This is a log entry.");
addressee.setName("John Smith");
addressee.setEmailAddress("john.smith@acme.com.au");
logEntry.getAddressees().add(addressee);
logEntryService.save(logEntry);
}
}
当我运行单元测试时,我收到以下错误:
java.sql.SQLException:分配连接时出错。原因:无法分配连接,因为:java.net.ConnectException:在端口1527上连接到服务器localhost时出错,并显示消息Connection refused。
关于我做错了什么(或根本不做)的任何想法?
由于
答案 0 :(得分:1)
那是:
@BeforeClass
public static void beforeClass() {
context = EJBContainer.createEJBContainer().getContext();
}
应该是:
@BeforeClass
public static void beforeClass() {
Properties properties = new Properties();
properties.setProperty(Context.INITIAL_CONTEXT_FACTORY, "org.apache.openejb.client.LocalInitialContextFactory");
context = new InitialContext(properties);
}
另外,因为HSQLDB是一个非JTA数据源,我需要指定我的persistence.xml持久性单元,如下所示:
<persistence-unit name="wyvern-unit" transaction-type="RESOURCE_LOCAL">
