我使用 Java 8、glassfish 5 build 25、Eclipse。我正在尝试从 Java EE 7 升级到 Java EE 8。所以我从这个简单的示例开始。

Web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://xmlns.jcp.org/xml/ns/javaee"
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
    id="WebApp_ID" version="4.0">
    <display-name>Play ID</display-name>
    <context-param>
        <param-name>javax.faces.PROJECT_STAGE</param-name>
        <param-value>Development</param-value>
    </context-param>
    <servlet>
        <servlet-name>Faces Servlet</servlet-name>
        <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>Faces Servlet</servlet-name>
        <url-pattern>*.xhtml</url-pattern>
    </servlet-mapping>
</web-app>

CDI 豆：

@Named
@ViewScoped
public class CommentFront implements Serializable {
    private static final long serialVersionUID = 1L;

    public void addComment() {
        System.out.println("I don’t work: ");   
    } 
}

简单的 JSF 页面 comment.xhtml

<!DOCTYPE html >
<html lang="en" 
    xmlns="http://www.w3.org/1999/xhtml" 
    xmlns:h="http://xmlns.jcp.org/jsf/html"
    xmlns:c="http://xmlns.jcp.org/jsp/jstl/core"
    >
<h:head>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no" />
    <title>Derbyware</title>

<h:body>
    <h:form id="form">
        <h:commandButton id="OneBtn" value="1 Comment" action="#{commentFront.addComment()}" >  
        </h:commandButton>

    </h:form>
</h:body>
</h:head>
</html>

错误：

javax.el.PropertyNotFoundException: /comment.xhtml @17,89 action="#{commentFront.addComment()}": Target Unreachable, identifier 'commentFront' resolved to null

当我第一次启动 glassfish 时，它会打印：

    2018-10-31T14:26:57.985+0000|Info: WELD-000411: Observer method [BackedAnnotatedMethod] public org.glassfish.jms.injection.JMSCDIExtension.processAnnotatedType(@Observes ProcessAnnotatedType<T>) receives events for all annotated types.

为什么像这样简单的东西在 glassfish 5 上不起作用？？？？

解决方案1：

我从 将 faces-config.xml 从 2.2 更改为 2.3 的答案中使用了这个导致 javax.el.PropertyNotFoundException: Target Unreachable, identifier 'bean' resolve to null

import javax.enterprise.context.ApplicationScoped;
import javax.faces.annotation.FacesConfig;

@ApplicationScoped
@FacesConfig(version = FacesConfig.Version.JSF_2_3)
public class JSFActivator {

}

现在一切正常。

解决方案2：

切换到 Payara 5.183，它开箱即用。不需要解决方案1

意见：为什么玻璃鱼这么坏。Java EE 8 的参考实现应用程序服务器如何在如此简单的工作中失败，真是可悲。我希望现在它已经从 Oracle 转向 Eclipse。

我想我会改用 Payara，直到 glassfish 修复。
