无法在带有JSF 2.3的Wildfly 14中注入FacesContext（Mojarra，主模块） [英] FacesContext not injectable in Wildfly 14 with JSF 2.3 (Mojarra, main module)

问题描述

我有一个豆子：

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 ...

this should work with 2.3 ...

部署到Wildfly 14时，结果为：

When deploying to Wildfly 14, this results in:

我的faces-config.xml是：

My faces-config.xml is:

<?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"
              xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-facesconfig_2_3.xsd"
              version="2.3">
    ...

问题：

这里出了什么问题以及如何解决这个问题？

What's wrong here and how do you solve this?

顺便说一句，这里的答案没有解决：如何使用JSF 2.3和TomEE注入FacesContext？

BTW the answer here didn't solve it: How to inject FacesContext with JSF 2.3 and TomEE?

推荐答案

根据

https://github.com/javaserverfaces/mojarra#activating-cdi-in-jsf-23

这是答案：

默认情况下，JSF 2.3将以JSF 2.2方式运行关于CDI支持。使用兼容JSF 2.3的 faces-config.xml 甚至
。换句话说，
是新的JSF 2.3注入功能和JSF工件的EL解析功能
（规格问题1316 ）只有在您明确激活它后才能起作用。
换句话说， @Inject FacesContext 默认情况下不起作用。为了使JSF 2.3完全向后兼容，必须使用
。

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.

当前只有一种方法可以在JSF 2.3和
中激活CDI。因此，可以使JSF 2.3以完整的JSF 2.3方式运行。将
@FacesConfig 注释放在任意CDI托管bean上。以
为例，它是一个常规的启动/配置Bean。

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，否则该注释将不起作用。之后，在我的启动中，控制台最终显示：

You need the @ApplicationScoped annotation or it will not work. After that in my startup the console finally displays:
