我正在使用 CDI-Unit JARhttp://jglue.org/cdi-unit/以便能够在我的 JUnit 4 测试中使用 CDI，我已经注入了我的 EJB 并调用了一个方法来持久化一个Client对象，但是我收到以下错误：

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，但我遇到了另一个错误：

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);
    }

}

这是我的 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，我收到此错误：

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

WELD-001475: The following beans match by type, but none have matching qualifiers:
  - Managed Bean [class com.proj.EJB.OperationsEJB] with qualifiers [@EJbQualifier @Any]

先感谢您。

@Ejb 的注解替换类型使得应该注入的 bean 必须具有注解 @Default。

@Stateless
@Default 
public class OperationsEJB {

应该有帮助。

也许：ejb-cdi-unit可以提供帮助。我们遇到了类似的问题，并为此在 cdi-unit 之上创建了一个额外的模块。
