显示每个操作的成功/失败响应答案

【问题标题】：Display Success/Failure response for each operation显示每个操作的成功/失败响应
【发布时间】：2016-01-01 22:28:24
【问题描述】：

我想在我的页面上显示每个操作的响应消息。当更新用户并且操作成功时，我想显示一条可关闭的消息：

“用户成功更新”如果操作不成功我想显示我在服务器端遇到的错误或异常。

我已尝试使用此处的示例： http://www.primefaces.org/showcase/ui/message/messages.xhtml

几个问题：

消息不可关闭
所有消息同时显示，我无法为消息附加密钥，即使我为每条消息使用了不同的“for”属性。

    public void updateNormalIdentifier(NormalIdentifier normalIdentifier) {
        ...
        FacesContext.getCurrentInstance().addMessage("Message1", new FacesMessage(FacesMessage.SEVERITY_INFO, "Update", "Update"));

    public void insertNormalIdentifier(Integer userId) {

        } catch (Exception e) {
            logger.error(e, e);
        }
    }


    public void removeNormalIdentifier(NormalIdentifier identifier) {
      ...
    }
}

我使用过“p:message”，但现在，我如何在几秒钟后隐藏消息。另外，当页面重新加载时，我如何清除所有消息。这是更新的代码：

【问题讨论】：

您可以在每个阶段使用一些可以通用的通知机制来发送不同类型的通知。想到了 Cometd，您可以使用它在每个步骤中向客户端发送消息。
您尝试在 3.1.1 上使用 5.2.x 展示示例...不好

标签： spring jsf-2 primefaces

【解决方案1】：

如果你想使用for 属性，你应该使用<p:message 而不是<p:messages。

很遗憾，closable 属性仅在更新版本的<p:messages 元素上可用。
