当我的页面无法正确呈现时，我会在 jboss 控制台中看到此信息。有谁知道这是什么意思？

Answer 1

部署新的 EAR 时或 war从时间设置与部署应用程序的服务器的时间设置不同的机器创建，刷新 JSF组件可能发生。

日志将显示以下错误。

原因是，每当发出新请求时，服务器都会将页面视为在 future 时间戳中进行了修改并再次开始编译。这会导致再次创建组件树，从而导致组件存储的所有状态丢失。

要解决此问题，请添加 facelets.REFRESH_PERIOD到 web.xmlREFRESH_PERIOD指示，当请求页面时，编译器应检查更改的时间间隔(以秒为单位)。如果您不希望编译器在编译页面后检查更改，则使用值 -1 .设置低刷新周期有助于在开发过程中编辑正在运行的应用程序中的页面。
web.xml ，应该是这样的，

<context-param>
<param-name>facelets.REFRESH_PERIOD</param-name>
<param-value>-1</param-value>
</context-param>

-1表示不检查更改，因为生产服务器设置此值是安全的。
