使用 Eclipse 的 Facelets 中的 EL 建议/自动完成/代码辅助 [英] EL proposals / autocomplete / code assist in Facelets with Eclipse

问题描述

我尝试在 Facelets 页面中激活 EL 提议，但是当我按 Ctrl+Space 时，它​​不起作用.由于其他问题，我设法激活了 JSF 标签提案，但 EL 提案不起作用.

如何在 Eclipse 中激活此功能?这是一个已知问题吗?

例如:

解决方案

Eclipse 不支持开箱即用.甚至 JSP 中的支持也非常有限.只有 的属性和 faces-config.xml 中硬编码为 的托管 bean 可用通过自动完成.然而，有一些插件支持 @ManagedBean 和 @Named bean 上的 EL 自动完成.

例如，被告知可以很好地用于 JSP 中的 EL 提案，但我不确定小脸.几年前，我在为 JSP 安装和配置插件方面没有很好的经验.

另见:

• 属性Eclipse 自动完成快捷方式不显示使用复合组件的新标签

I tried to activate EL proposals in a Facelets page, but when I hit Ctrl+Space, it doesn't work. I managed to activate JSF tag proposals thank to other questions, but EL proposals aren't working.

How can I activate this feature in Eclipse? Is it a known issue?

For example:

<h:inputHidden id="id" value="#{Ctrl+Space not working!}"/>

解决方案

Eclipse doesn't support this out the box. Even the support in JSP is very limited. Only the properties of <jsp:useBean> and managed beans hardcoded as <managed-bean> in faces-config.xml are available by autocomplete. There are however plugins which supports EL autocomplete on @ManagedBean and @Named beans.

For example, the JBoss Tools plugin (specifically the CDI feature) which can be installed as described here: How do I Install JBoss AS / WildFly Server in Eclipse for Java EE.

(which has in its current 3.2.0 version unicode bugs, as you see above in the rightmost window)

You can even use Ctrl+Click on the managed bean name #{bean} in an EL expression in Facelets file to navigate to the concrete backing bean class. You can also use Ctrl+Shift+G on the managed bean method in a backing bean class to find all references to the particular property or action in Facelets files.

The Aptana plugin is told to work fine for EL proposals in JSPs, but I am not sure for Facelets. I didn't had good experiences with installing and configuring the plugin for JSP some years ago.
