如何在Glassfish 3.1中结合@Asynchronous和Weld / CDI事件和@Observes（at = TransactionPhase.AFTER_COMPLETION） [英] How do I combine @Asynchronous and Weld/CDI Events and @Observes(during=TransactionPhase.AFTER_COMPLETION) in Glassfish 3.1

问题描述

首先让我声明，以下代码示例在GF 3.0.1中工作正常。当我们切换到GF 3.1时，麻烦就开始了。

我正在使用一种方法

 code> @Asynchronous 
 public void executeFlowStep（
 @Observes（during = TransactionPhase.AFTER_COMPLETION）
 ExecuteFlowStepEvent executeFlowStepEvent）{
  

由于交换机，每当这样收到一个 ExecuteFlowStepEvent ，我会收到以下错误消息：

  WELD-000401通知观察者事件[package]时失败.ExecuteFlowStepEvent 
  

没有给出进一步的信息或堆栈跟踪。
如果我删除 @Asynchronous 注释和 AFTER_COMPLETION 属性，那么这样做会打破程序因为我依赖于 AFTER_COMPLETION 时间。

我试图向焊工论坛寻求帮助，到目前为止尽管似乎还有其他人遇到同样的问题： http://seamframework.org/Community/WeldUsers

我至少想知道：
这是一个bug，还是这个想要的。这是否意味着Weld不能使用异步方法/ AFTER_COMPLETION属性？为什么在GF 3.0.1中工作？
有没有人设法在GF 3.1上做这个工作？

解决方案

根据链接您作为对自己的问题的评论发布，这是一个在Wield 1.1.2和GlassFish 3.1中修复的错误.2（build 14 +）。

First of all let me state, that the following code example worked just fine in GF 3.0.1. The troubles started when we switched to GF 3.1.

I'm using a method

@Asynchronous
public void executeFlowStep(
    @Observes(during=TransactionPhase.AFTER_COMPLETION) 
    ExecuteFlowStepEvent executeFlowStepEvent) { 

Since the switch, whenever this should receive an ExecuteFlowStepEvent I get the following error message:

WELD-000401 Failure while notifying an observer of event [package].ExecuteFlowStepEvent

No further information or stacktrace is given. It works if I remove the @Asynchronous annotation and the AFTER_COMPLETION attribute, of course this breaks the program as I depend on the AFTER_COMPLETION timing.

I tried to ask for help on the Weld Forums, so far to no avail, although there seem to be other people with the same problem: http://seamframework.org/Community/WeldUsers

I at least would like to know: Is this a bug, or is this wanted. Does this imply that Weld does NOT work with Asynchronous methods/AFTER_COMPLETION attributes? Why did this work in GF 3.0.1? Has anyone managed to make this work on GF 3.1?

解决方案

According to the link you posted as a comment to your own question, this is a bug that was fixed in Wield 1.1.2 and GlassFish 3.1.2 (build 14+).
