使用 JSF 2.3（Mojarra，主模块）在 Wildfly 14 中不可注入 FacesContext
FacesContext not injectable in Wildfly 14 with JSF 2.3 (Mojarra, main module)
我有一颗豆子：
import javax.faces.context.FacesContext;
import javax.faces.view.ViewScoped;
...
@Named
@ViewScoped
public class SimpleBean implements Serializable
{
private static final long serialVersionUID = 1L;
@Inject
protected FacesContext facesContext;
...
}
根据
https://arjan-tijms.omnifaces.org/p/jsf-23.html#1316
这应该适用于 2.3 ...
部署到 Wildfly 14 时，结果为：

问题:
这里出了什么问题，你是如何解决这个问题的？
顺便说一句，这里的答案没有解决：How to inject FacesContext with JSF 2.3 and TomEE?
根据
https://github.com/javaserverfaces/mojarra#activating-cdi-in-jsf-23
这是答案：
By default, JSF 2.3 will run in JSF 2.2 modus as to CDI support. Even
when you use a JSF 2.3 compatible faces-config.xml. In other words,
the new JSF 2.3 feature of injection and EL resolving of JSF artifacts
(spec issue 1316) won't work until you explicitly activate this.
In other words, @Inject FacesContext doesn't work by default. This
is necessary in order for JSF 2.3 to be fully backwards compatible.
There is currently only one way to activate CDI in JSF 2.3 and
herewith make JSF 2.3 to run in full JSF 2.3 modus. Put the
@FacesConfig annotation on an arbitrary CDI managed bean. For
example, a general startup/configuration bean.
@FacesConfig
@ApplicationScoped
public class YourApplicationConfig {
// ...
}
完整示例：
import javax.enterprise.context.ApplicationScoped;
import javax.faces.annotation.FacesConfig;
@FacesConfig
@ApplicationScoped
public class Jsf23Activator {
// ...
}
您需要 @ApplicationScoped 注释，否则它将不起作用。在那之后，在我的启动中，控制台最终显示：
