为什么 WildFly 10 + JSF 2.3 不能与 Omnifaces 2.6.1 一起使用？

【问题标题】：Why is WildFly 10 + JSF 2.3 not working with Omnifaces 2.6.1?为什么 WildFly 10 + JSF 2.3 不能与 Omnifaces 2.6.1 一起使用？

【问题描述】：

我一直在尝试在 Wildfly 10 上使用 jsf 2.3、primefaces 6 和 omnifaces 2.6.1 启动并运行应用程序。

我已经拆分了 jsf 2.3（api 和 impl）并完成了 WildFly 的设置。

应用程序可以顺利启动，无需全方位 2.6.1。但是当我将omnifaces jar添加到应用程序类路径（/ lib）时，这个jar在启动时失败，出现下一个异常：

堆栈跟踪显示方法 javax.faces.application.Application.getSearchExpressionHandler 正在进入“else”块内

    public SearchExpressionHandler getSearchExpressionHandler() {

    if (defaultApplication != null) {
        return defaultApplication.getSearchExpressionHandler();
    } else {
        throw new UnsupportedOperationException();
    }

    }

这显然意味着 defaultApplicatoin 为空。有什么理由吗？我是否遗漏了 omnifaces 2.6.1/jsf 2.3 的任何重要配置？

提前致谢！

    【解决方案1】：

    这是 WildFly 中的一个错误。我已经举报了：http://issues.jboss.org/browse/WFLY-8815.

    重要的是，它的内置 WeldApplication 具有硬编码的 JSF 2.2 依赖项。它实际上应该从 JSF javax.faces.application.ApplicationWrapper 扩展而来，它已经预定义了所有默认委托方法，例如 getSearchExpressionHandler()，但是与 JSF 2.2 相关的 WeldApplication 没有那个，因此您面临的异常。

    OmniFaces 没有错，它只是一个触发器。对于任何其他具有自定义 javax.faces.application.Application 实现的以 JSF 为目标的库，您将面临完全相同的问题。

    如果将 JSF 降级回 2.2 不是一个选项，并且您没有耐心等待 WildFly 人员修复它，那么您可以如下修改 WildFly 修复其损坏的 WeldApplication。

    1. 在org.jboss.as.jsf.injection.weld.WeldApplication 中找到source code（注意：因此不是 org.jboss.weld.environment.servlet.jsf.WeldApplication 确实修复了这个错误already！这仅适用于Tomcat 之类的东西）。

    2. 从

      调整类签名 
      public class WeldApplication extends ForwardingApplication {

      到

      public class WeldApplication extends ApplicationWrapper {

    3. 替换构造函数中的第一行

      this.application = application;

      通过

      super(application);

    4. 删除此方法

      @Override
protected Application delegate() {
    init();
    return application;
}

    5. 替换两次出现的

      application.getExpressionFactory()

      通过

      getWrapped().getExpressionFactory()

    6. 编译它，你会得到两个类：WeldApplication.class和WeldApplication$AdjustableELResolver.class。

    7. 转到 WildFly 安装的 /modules/system/layers/base/org/jboss/as/jsf-injection/main 文件夹。

    8. 在那里解压wildfly-jsf-injection-10.1.0.Final.jar。

    9. 浏览并删除解压 JAR 的 /org/jboss/as/jsf/injection/weld 子文件夹中的所有三个 WeldApplication***.class 文件，并将两个新编译的文件放入其中。

    10. 将文件夹重新压缩到新的wildfly-jsf-injection-10.1.0.Final.jar，覆盖旧的。

    11. 利润。

    【讨论】：

    • 非常感谢您的回答@BalusC！我会立即尝试修复！
    • 仅供参考：JBoss 的家伙今天已经修复了它。它将在下一个 WildFly 版本中发布。
