Question

我想在我的页面上显示每个操作的响应消息。更新用户并且操作成功时，我想显示一个可关闭的消息：

＆＃34;用户已成功更新＆＃34;如果操作不成功，我想显示我在服务器端获得的错误或异常。

我尝试过使用这里的示例： {{3}}

几个问题：

消息不可关闭
所有消息都是同时显示的，即使我使用了不同的＆＃34;用于消息，我也无法将密钥附加到消息上。每条消息的属性。

我正在使用：

<dependency>
    <groupId>org.primefaces</groupId>
    <artifactId>primefaces</artifactId>
    <version>3.1.1</version>
</dependency>

豆：

    public void updateNormalIdentifier(NormalIdentifier normalIdentifier) {

        FacesContext.getCurrentInstance().addMessage("Message1", new FacesMessage(FacesMessage.SEVERITY_INFO, "Update", "Update"));
    }

    public void insertNormalIdentifier(Integer userId) {
        try {
            ..
            FacesContext.getCurrentInstance().addMessage("Message2", new FacesMessage(FacesMessage.SEVERITY_ERROR, "Insert", "Insert"));
        } catch (Exception e) {
            logger.error(e, e);
        }
    }


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

我已经使用了＆＃34; p：message＆＃34;，但现在，我怎样才能在几秒钟后隐藏消息。另外，如何在页面重新加载时清除所有消息。这是更新的代码：

Answer 1

如果您想使用<p:message属性，则应使用<p:messages代替for。

不幸的是，closable属性仅适用于更新版本的<p:messages元素。
