使用EJB时不使用CDI的Java

Question

为了能够在我的http://jglue.org/cdi-unit/ 4测试中使用CDI，我使用了CDI，我注入了JUnit并调用了一个方法来持久化一个Client对象，但是我得到了以下错误：

java.lang.NoClassDefFoundError org/jboss/weld/environment/se/Weld

我的无状态EJB (OperationsEJB.java)：

@Stateless
public class OperationsEJB {

    @PersistenceContext(unitName="db_PU")
    EntityManager em;

    public void addClient(Client client) {

        try {
            em.persist(client);
        } catch (Exception e) {

        }
    }
}

我的JUnit测试：

import static org.junit.Assert.*;
import javax.inject.Inject;
import org.jglue.cdiunit.AdditionalClasses;
import org.jglue.cdiunit.CdiRunner;
import org.jglue.cdiunit.ejb.SupportEjb;
import org.junit.Test;
import org.junit.runner.RunWith;

@RunWith(CdiRunner.class)
@AdditionalClasses(OperationsEJB.class)
@SupportEjb
public class TestApp {

    @Inject
    OperationsEJB ejb;

    @Test
    public void test() {

        Client c1 = new Client();
        c1.setNomClient("client1");

        ejb.addClient(c1);

        assertNotNull(c1);
    }

}

我没有使用Maven，我已经下载了weld-se-core-2.3.0.Final.jar，并发现了另一个错误：

java.lang.NoClassDefFoundError: org/jboss/weld/environment/ContainerInstanceFactory

编辑:

现在我正在使用Maven，这是我的JUnit测试代码：

OpTest.java：

@RunWith(CdiRunner.class)
@AdditionalClasses({OperationsEJB.class})
@SupportEjb
public class OpTest {

    @Inject
    OperationsEJB ejb;

    @Test
    public void test() {


        assertNotNull(ejb);
    }

}

以下是我的EJB：

@Stateless
public class OperationsEJB {

    @PersistenceContext(unitName = "db_PU")
    EntityManager em;

    public void addClient(Client client) {

        em.persist(client);
    }
}

当我运行测试时，我会得到以下错误：

Oct 18, 2015 3:59:04 PM org.jboss.weld.bootstrap.WeldStartup <clinit>

JUnit日志中显示的错误是：

org.jboss.weld.exceptions.DeploymentException: WELD-001408: Unsatisfied dependencies for type OperationsEJB with qualifiers @Default
  at injection point [UnbackedAnnotatedField] @Inject @EJB proj.OpTest.ejb
  at proj.OpTest.ejb(OpTest.java:0)
WELD-001475: The following beans match by type, but none have matching qualifiers:
  - Managed Bean [class com.proj.EJB.OperationsEJB] with qualifiers [@EJbQualifier @Any]

提前谢谢你。

Answer 1

@Ejb的注释替换使得应该注入的bean具有注释@Default是必要的。

@Stateless
@Default 
public class OperationsEJB {

应该能帮上忙。

也许：ejb单元可以帮上忙。我们也有类似的问题，并为此在cdi单元之上创建了一个额外的模块。
