Question

自JPA 2.1起，可以将EJB注入实体侦听器。但是，WildFly 9.0.2最终失败，出现以下异常。

提出这个问题只是因为我读到了从WildFly 8.2开始向实体监听器注入EJB和/或CDI事件的地方。因此，我觉得我在某个地方出错了。

与GlassFish成功（至少在GlassFish 4.1上）不同，WildFly是否要求我们特别注意将EJB和/或CDI事件注入实体监听器？

我在一个完全空白的企业应用程序上对此进行了测试，该应用程序只有一个空白会话bean（无状态），它将被注入实体监听器和一些JPA实体。

听众：

public class ProductListener {

    @Inject
    private TestService service;

    @PostPersist
    public void postPersist() {

    }
}

EJB完全空白：

@Stateless
public class TestBean implements TestService {

}

如果注入点（TestService）被删除，则异常消失。

使用@ApplicationScoped或@Singleton指定听众也无济于事（实际上不应该这样做）。

Hibernate版本最终为5.0.5，Weld版本为2.2.16。

更新1：

更新到Hibernate 5.0.6 final。

更新2：

问题仍然存在于2016年1月29日星期五发布的 WildFly 10.0.0 final ，其中Hibernate 5.0.7 final / Weld 2.3 final。

更新3：

根据issue status，这已经在Hibernate 5.1.0 final中得到修复，它应该在WildFly 10.0.0 final中相应地工作，但它仍然无法使用相同的异常 - 没有任何改进。

Answer 1

正如@Franck所指出的，它是一个错误，最终于去年仅在版本11（wildfly）中得到修复（在EAP 7.1中也得到了修复）。我们使用EAP 7.0（wildfly 10）和相同的问题，我们无法升级。解决方法是，我们现在使用@Tiny的建议，将功能移至EJB并使用@EJB iso @Inject。
