全局JSF异常处理程序不'；我不能抓住所有的错误

我实现了一个异常处理程序，如本页所述：

遗憾的是，我仍然收到一些错误，这些错误不是由这个解决方案处理的。你知道如何捕捉所有错误吗

我的处理人没有发现这一点：

服务JSF请求时未引发此异常。它是在执行异步EJB服务调用时抛出的。也就是说，运行在不同于服务JSF请求的线程中

由于它是异步执行的，因此无法在返回JSF请求结果的响应中获得任何异常。因此，如果不删除

@Asynchronous

注释使其同步，就不可能让它最终进入JSF错误页面

无论如何，如果将其呈现到错误页面并不那么重要，但实际上您对日志/邮件/任何内容更感兴趣，那么您可以使用拦截器获取（异步）EJB服务调用期间引发的任何异常，如下所示：

public class ExceptionHandlerInterceptor {

    @AroundInvoke
    public Object logExceptions(InvocationContext context) throws Exception {
        try {
            return context.proceed();
        }
        catch (Exception e) {
            // Log/mail/whatever it here.

            throw e; // Don't forget to rethrow!
        }
    }

}

只需将该类放在EJB项目中的某个位置，并通过EJB类上的

@Interceptors

注释注册它

@Stateless
@Interceptors(ExceptionHandlerInterceptor.class)
public class FooService {}

或者通过

/META-INF/EJB jar.xml

中的以下条目在整个EJB项目范围内：

<interceptors>
    <interceptor>
        <interceptor-class>com.example.ExceptionHandlerInterceptor</interceptor-class>
    </interceptor>
</interceptors>
<assembly-descriptor>
    <interceptor-binding>
        <ejb-name>*</ejb-name>
        <interceptor-class>com.example.ExceptionHandlerInterceptor</interceptor-class>
    </interceptor-binding>
</assembly-descriptor>

com.example.ExceptionHandlerInterceptor
*
com.example.ExceptionHandlerInterceptor

这是在ajax请求期间还是在常规HTTP请求期间发生的？遗憾的是，此方法尚未触发。我读到一些关于CDI+接收器不起作用的消息？还有别的办法吗？
