为什么@Resource + @EJB适用于EJB样式拦截器而不适用于CDI拦截器？

我的问题类似于 @InterceptorBinding / CDI/ EJB 3.2 - problems with injection

但我的问题是：为什么资源/ EJB注入对EJB拦截器工作正常，但在以CDI方式执行时会中断？ 特别是因为在所有其他情况下，EJB和CDI在Java EE 7中的工作方式非常相似（@Inject + @JJB在POJO中......）

这个差异是在某处记录还是错误？

设置 Glassfish 4.1（EJB 3.2），Weld 2.2.2.Final（CDI 1.1）=＆gt; Java EE 7

工作资源注入（EJB） 

public class ResourceInjectedInterceptor {

    @Resource(name = "java:comp/DefaultManagedExecutorService")
    private ManagedExecutorService managedExecutorService;

    @Resource
    private ManagedExecutorService managedExecutorService2;

    @EJB
    private SomeEjb someEjb;

    @AroundInvoke
    public Object intercept(InvocationContext ctx) throws Exception {
        return ctx.proceed();
    }
}

@Stateless
public class InterceptedBean {

    @Interceptors(AsyncTestInterceptor.class)
    public void beingIntercepted() {
        //...
    }
}

在上面的版本中，所有三个managedExecutorService，managedExecutorService2和someEjb都被注入，拦截器也按预期工作。

资源注入损失（CDI） 

@Intercept
@Interceptor
public class ResourceInjectedInterceptor {

    @Resource(name = "java:comp/DefaultManagedExecutorService")
    private ManagedExecutorService managedExecutorService;

    @Resource
    private ManagedExecutorService managedExecutorService2;

    @EJB
    private SomeEjb someEjb;

    @AroundInvoke
    public Object intercept(InvocationContext ctx) throws Exception {
        return ctx.proceed();
    }
}

@Inherited
@InterceptorBinding
@Retention(RUNTIME)
@Target({METHOD, TYPE})
public @interface Intercept {
}

public class InterceptedBean {

    @Intercept
    public void beingIntercepted() {
        //...
    }
}

<beans bean-discovery-mode="all"
       xmlns="http://xmlns.jcp.org/xml/ns/javaee"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/beans_1_1.xsd">
    <interceptors>
        <class>com.xxx.ejb.ResourceInjectedInterceptor</class>
    </interceptors>
</beans>

在运行时实例化拦截器时导致此异常（请参阅下面的完整堆栈跟踪） - 没有名称的@Resource无法按预期工作：

Caused by: javax.naming.NameNotFoundException: 
    No object bound to name java:comp/env/com.xxx.ejb.ResourceInjectedInterceptor/managedExecutorService2

删除managedExecutorService2＆＃34;修复＆＃34;问题，但是有一些Ejb的模拟异常。删除someEjb也会导致一个缺少重要部分的工作iterceptor：）

我尝试了什么

  • 尝试各种注释更改，直到我明白它基本上归结为EJB与CDI
  • 将@ javax.annotation.ManagedBean添加到CDI拦截器
  • 搜索Glassfish / Weld相关错误报告
  • 想知道lookup-name＆＃34; java：comp / env / com.xxx.ejb.ResourceInjectedInterceptor / managedExecutorService2＆＃34;在错误消息中生成它应该是＆＃34; java：comp / DefaultManagedExecutorService＆＃34;如在手动查找中
  • reading in the weld documentation没有找到任何线索
