我添加了一个PhaseListener到faces-config.xml:

<lifecycle>
    <phase-listener>com.project.NotificationListener</phase-listener>
</lifecycle>

这个类似乎是正确的,因为它非常简单.

public class NotificationListener implements PhaseListener {

    @Inject
    private MyCDIStuff stuff;

    @Override
    public PhaseId getPhaseId() {
        return PhaseId.RENDER_RESPONSE;
    }

    @Override
    public void beforePhase(PhaseEvent event) {
        this.stuff.doStuff();
    }
}

'beforePhase'方法被正确调用,但MyCDIStuff对象为null.我尝试使用@Singleton最可能不正确的类的注释,并且它也没有使注入工作.

有没有办法注入CDI托管bean PhaseListener？

我搜索了每一个地方,但似乎我找不到最好的答案让我解决这个错误,有我的堆栈跟踪,有人可以告诉我发生了什么事情,我花了两个约会来找到这个错误.... :(
