为什么 WildFly 10 + JSF 2.3 不能与 Omnifaces 2.6.1 一起使用？
Why is WildFly 10 + JSF 2.3 not working with Omnifaces 2.6.1?
我一直在尝试在 Wildfly 10 上使用 jsf 2.3、primefaces 6 和 omnifaces 2.6.1 启动应用程序并运行。
我已经拆分了 jsf 2.3（api 和 impl）并完成了 WildFly 的设置。
应用程序在没有 omnifaces 2.6.1 的情况下顺利启动。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，给出下一个异常：

提前致谢！
这是 WildFly 中的错误。我已经举报了：http://issues.jboss.org/browse/WFLY-8815.
到目前为止，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的委托方法，例如 getSearchExpressionHandler()，但是 JSF 2.2-tied WeldApplication 没有那个，因此你例外面对。
OmniFaces 没有错，它只是一个触发器。对于具有自定义 javax.faces.application.Application 实现的任何其他以 JSF 为目标的库，您会遇到完全相同的问题。
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。
找到source code of org.jboss.as.jsf.injection.weld.WeldApplication (note: thus not org.jboss.weld.environment.servlet.jsf.WeldApplication which indeed has this bug already修复！这仅适用于 Tomcat).
调整 class 来自
的签名
public class WeldApplication extends ForwardingApplication {
到
public class WeldApplication extends ApplicationWrapper {
替换构造函数中的第一行
this.application = application;
来自
super(application);
删除此方法
@Override
protected Application delegate() {
init();
return application;
}
替换两次出现的
application.getExpressionFactory()
来自
getWrapped().getExpressionFactory()
编译它，你会得到两个class：WeldApplication.class和WeldApplication$AdjustableELResolver.class。
转到 WildFly 安装的 /modules/system/layers/base/org/jboss/as/jsf-injection/main 文件夹。
在那里解压 wildfly-jsf-injection-10.1.0.Final.jar。
浏览并删除解压缩 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在那里。
将文件夹重新压缩到新的 wildfly-jsf-injection-10.1.0.Final.jar，覆盖旧的。
利润。
