问题描述

我写了一个PhaseListener，我正在其中检查验证"阶段.有没有一种方法可以使我在侦听器的afterPhase()方法中检查验证是否失败，并且验证阶段之后的下一个阶段将是渲染响应"阶段.

I have written a PhaseListener in which I am checking for the Validations phase. Is there a way using which I can check in the afterPhase() method of listener that validation has failed and the next phase after the Validation phase will be Render Response phase.

推荐答案

如何使用FacesContext，您可以检查是否有入队消息吗?例如

How about using FacesContext, can you check if there are any enqueued messages? Eg.

FacesContext context = FacesContext.getCurrentInstance();
Iterator<FacesMessage> messages = context.getMessages();
