我有一个bean：
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…
当部署到Wildfly 14时，这将导致：

我的faces-config.xml是：
<?xml version="1.0" encoding="UTF-8"?>
<faces-config xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

问题：
这里出了什么问题，你如何解决？
顺便说一句，这里的答案并没有解决这个问题：如何用JSF 2.3和TomEE注入FacesContext？
根据
https://github.com/javaserverfaces/mojarra#activating-cdi-in-jsf-23
这就是答案：
默认情况下，JSF 2.3将以JSF 2.2的方式运行，以支持CDI。即使当您使用JSF 2.3兼容的CCD_ 1时。换句话说，JSF 2.3注入和JSF工件EL解析的新特性(规范第1316期(在您明确激活之前不会工作。换句话说，默认情况下
@Inject FacesContext不起作用。这为了使JSF 2.3完全向后兼容，这是必要的。目前只有一种方法可以在JSF 2.3中激活CDI，并且在此使JSF 2.3在完整的JSF 2.3模式中运行。把任意CDI托管bean上的
@FacesConfig注释。对于例如，一个通用的启动/配置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，在我的启动控制台最终显示：
