Question

我使用JBoss来部署使用CDI和CD的应用程序。 EJB。

“applicationContext.xml”包含JTA数据源连接。
“test-applicationContext.xml”包含RESOURCE_LOCAL数据源连接。

===案例1 ====

我有一个像这样的CDI bean：

@Named
@Transactional
public class EmployeeRoleInserter {
    @PersistenceContext(unitName = PersistenceConstants.PERSISTENCE_UNIT)
    private EntityManager entityManager;
...
}

和这样的JUnit测试：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:/test-applicationContext.xml"})
public class EmployeeRoleInserterTest {
    @Inject
    private EmployeeRoleInserter inserter;

    @Test
    public void testInsert() {

JUnit测试和事务有效，但JBboss上的部署会产生错误：

===案例2 ====

EJB bean：

@Stateless
public class EmployeeRoleInserter {     
    @PersistenceContext(unitName = PersistenceConstants.PERSISTENCE_UNIT)
    private EntityManager entityManager;

JUnit测试：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:/test-applicationContext.xml"})
public class EmployeeRoleInserterTest {
    @EJB
    private EmployeeRoleInserter inserter;

    @Test
    public void testInsert() {

测试用例会产生错误：

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.devinition.policy.employee.registration.EmployeeRoleInserter] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

但JBoss上的部署可以很好地处理事务！

===案例3 ===

最后我混合了它们（CDI和EJB）：

@Named
@Stateless
@Transactional
public class EmployeeRoleInserter {
    @PersistenceContext(unitName = PersistenceConstants.PERSISTENCE_UNIT)
    private EntityManager entityManager;

JUnit的

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:/test-applicationContext.xml"})
public class EmployeeRoleInserterTest {
    @Inject
    private EmployeeRoleInserter inserter;

    @Test
    public void testInsert() {

JUnit测试和交易运作良好。

JBoss上的部署也可以，但是事务不起作用！我的意思是自动提交就像真的

=> The question is "How can I make it work on both JBoss and JUnit Test???"

Answer 1

EmployeeRoleInserter bean中的

不要使用类的@Transactional注释，而是将它用于保存其中对象的方法或者将CRUD操作放在事务manualy中，而不是使用@Transaction注释，因为@Transaction puts the whole operations inside one transaction

同时使用@Named和@Stateless
