Question

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 ...

部署到Wildfly 14时，结果为：

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"
              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：

这是怎么了？您该怎么解决？

顺便说一句，这里的答案没有解决：How to inject FacesContext with JSF 2.3 and TomEE?

Answer 1

根据

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

这是答案：

默认情况下，关于CDI支持，JSF 2.3将以JSF 2.2方式运行。甚至   当您使用与JSF 2.3兼容的Private Sub CommandButton21_Click() 'ActiveSheet.Unprotect "password" 'Change password accordingly. Dim x As Long Dim iCol As Integer Dim MaxRowList As Long Dim S As String Set wsSource = Worksheets("Sheet1") Set wsTarget = Worksheets("Sheet2") iCol = 1 MaxRowList = wsSource.Cells(Rows.Count, iCol).End(xlUp).Row For x = MaxRowList To 1 Step -1 S = wsSource.Cells(x, 16) If CDate(S) < Date Then AfterLastTarget = wsTarget.Cells(Rows.Count, 1).End(xlUp).Row + 1 wsSource.Rows(x).Copy wsTarget.Rows(AfterLastTarget).PasteSpecial Paste:=xlPasteValuesAndNumberFormats wsSource.Rows(x).Delete End If Next Application.ScreenUpdating = True 'ActiveSheet.Protect "password" 'Change password accordingly. MsgBox ("Update complete") End Sub时。换一种说法，   JSF 2.3的注入和EL解析的新JSF 2.3功能   （spec issue 1316）将不起作用，除非您明确激活它。   换句话说，faces-config.xml在默认情况下不起作用。这个   为了使JSF 2.3完全向后兼容，必须这样做。

在JSF 2.3和更高版本中，目前只有一种激活CDI的方法。   从而使JSF 2.3能够以完整的JSF 2.3方式运行。放在   在任意CDI托管bean上的@Inject FacesContext注释。对于   例如常规的启动/配置Bean。
@FacesConfig

完整示例：

@FacesConfig
@ApplicationScoped
public class YourApplicationConfig {
    // ...
}

您需要import javax.enterprise.context.ApplicationScoped; import javax.faces.annotation.FacesConfig; @FacesConfig @ApplicationScoped public class Jsf23Activator { // ... }批注，否则它将不起作用。之后，在我的启动中，控制台最终显示：

@ApplicationScoped

无法在带有JSF 2.3的Wildfly 14中注入FacesContext（Mojarra，主模块）
