JSF和自动重载xhtml文件 [英] JSF and automatic reload of xhtml files

问题描述

我在使用JRebel，Spring，JSF Mojarra 2.0.3和WebLogic 10.3热重新加载XHTML文件方面遇到了一些问题。

I had some problems with hot-reloading XHTML files using JRebel, Spring, JSF Mojarra 2.0.3 and WebLogic 10.3.

JRebel重新加载常规Java类和js / / WebContent下的css文件成功，但不是JSF的.xhtml文件。需要完整的重新发布才能在服务器上更新xhtml文件。

JRebel reloads regular Java classes and js/css files under /WebContent successfully, but not JSF's .xhtml files. A full republish was necessary to get xhtml files updated on the server.

通过反复试验我终于通过向web.xml添加一些facelets参数并创建它来实现它一个自定义的ResourceResolver，如所述这篇博文。

By trial and error I finally got it to work by adding some facelets parameters to web.xml and creating a custom ResourceResolver as described in this blog post.

但是，我想知道为什么会这样，更具体地说：

However, I wonder WHY this works, and more specifically:

• 为什么是需要自定义ResourceResolver吗？


• 是不是JRebel应该通过监视xhtml文件所在的/ WebContent来处理这个问题？


• 我猜它与Facelets / JSF通过FacesServlet编译xhtml到servlets（？）有什么关系，JRebel无法检测到它？

推荐答案

JRebel处理/ WebContent文件夹更改。

JRebel handles /WebContent folder changes.

问题是Facelets会进行缓存而不会重新读取已更改的文件。要强制重读，​​请在 web.xml 中指定以下参数。

The problem is that Facelets do caching and do not reread changed files. To force reread specify the following parameters in web.xml.

JSF 2 （ Facelets 2.x）：

JSF 2 (Facelets 2.x):

<!-- Time in seconds that facelets should be checked for changes since last request. A value of -1 disables refresh checking. -->
<context-param>
    <param-name>javax.faces.FACELETS_REFRESH_PERIOD</param-name>
    <param-value>0</param-value>
</context-param>

<!-- Set the project stage to "Development", "UnitTest", "SystemTest", or "Production". -->
<!-- An optional parameter that makes troubleshooting errors much easier. -->
<!-- You should remove this context parameter before deploying to production! -->
<context-param>
    <param-name>javax.faces.PROJECT_STAGE</param-name>
    <param-value>Development</param-value>
</context-param>

JSF 1.2 （Facelets 1.x）参数是：

---

For JSF 1.2 (Facelets 1.x) parameters are:

<context-param>
    <param-name>facelets.REFRESH_PERIOD</param-name>
    <param-value>0</param-value>
</context-param>
<context-param>
    <param-name>facelets.DEVELOPMENT</param-name>
    <param-value>true</param-value>
</context-param>

在您的情况下不需要自定义资源解析程序。资源解析器只是从自定义文件系统文件夹中获取xhtml文件的一种棘手的方法。在你的情况下，JRebel会这样做（甚至更多）。

That custom resource resolver is not needed in your case. That resource resolver is just a tricky way to get xhtml files from custom file system folder. In your case JRebel does that (and even more).
