当我启动 jboss 时，它返回：

我正在学习一些教程后的Java持久性.

我正在使用Java EE 7和Payara服务器.

我注意到每个使用不同的持久性方法.

例子:

• 简单

  @Stateless
  public class BookServiceBean implements BookService {
      @PersistenceContext
      private EntityManager em;
  
      public void createOrUpdate(Book book) {
          em.persist(book);
      }
      public void remove(Book book) {
          em.remove(book);
      }
  }

• with flush(),这是在persistene.xml中的 "AUTO"上没有设置验证策略时使用的,对吧？

  @Stateless
  public class BookServiceBean implements BookService {
      @PersistenceContext
      private EntityManager em;
  
      public void createOrUpdate(Book book) {
          em.persist(book);
          em.flush();
      }
      public void remove(Book book) {
          em.remove(book);
          em.flush();
      }
  }

我正在按照本教程,但我有一些问题来设置jdbc连接.

在我的arquillian.xml中,我写道:

...
<container qualifier="payara-remote" default="true">
    <configuration>
        <property name="resourcesXml">
            src/test/resources-payara-remote/glassfish-resources.xml
        </property>
    </configuration>
</container>
...

当我运行我的测试时,我收到此警告:

AVVERTENZA: Configuration contain properties not supported by the backing object org.jboss.arquillian.container.glassfish.remote_3_1.GlassFishRestConfiguration
Unused property entries: {resourcesXml=
            src/test/resources-payara-remote/glassfish-resources.xml
        }
Supported property names: [adminHttps, remoteServerHttpPort, libraries, type, remoteServerAddress, target, remoteServerAdminPort, remoteServerAdminHttps, adminUser, authorisation, adminPort, properties, adminHost, adminPassword]

所以我认为"resourceXml"不受支持......我如何告诉arquillian使用该文件？

而且,在该文件中我声明了一个jdbc/test.我必须在persistence.xml中编写什么才能使用该数据库连接？

先感谢您

UPDATE

我希望在"src/test/resources-payara-remote/glassfish-resources.xml"中使用我的test-db声明jdbc连接(不在远程服务器中创建jdbc连接),但我不知道如何设置arquillian以使用.xml文件中声明的jdbc连接.

我不知道为什么我无法捕获 EJB 中的方法抛出的 NoResultException ......

try {
    User user = userFacade.findByEmail(email);
    userController.setSelected(user);
    getSelected().setUserOid(user.getOid());
} catch (NoResultException noResultException) {
    JsfUtil.addErrorMessage("No user found with provided email");
    System.err.println(noResultException.getMessage());
} catch (EJBException e){
    System.err.println(e.getMessage());
}

EJB

@Stateless
public class UserFacade extends AbstractFacade<User> {

    ...

    public User findByEmail (String email) throws NoResultException{
        User user = em.createNamedQuery("User.findByEmail", User.class).
                setParameter("email", email).getSingleResult();
        return user;
    }

    ...

为什么这段代码会捕获 EJBException 而不是 NoResultException 以及如何捕获 NoResultException？

Avvertenza:   javax.ejb.EJBException
...
...
Caused by: javax.persistence.NoResultException: getSingleResult() did not retrieve any entities.
