Application类型中的getExpressionFactory()方法引用了缺少的ExpressionFactory类型

标签: maven jsf-2

我正在研究JSF 2.0应用程序,我正在尝试以编程方式将ajax操作添加到以编程方式创建的UIComponent(相当于在commandLink中静态声明的f:ajax侦听器),如this blog所示

当我尝试获取ExpressionFactory以创建MethodExpression时,这样:

FacesContext fc = FacesContext.getCurrentInstance();
Application application = fc.getApplication();
ExpressionFactory ef = fc.getApplication().getExpressionFactory();

所以,就在我写这些文字时,我收到了一个错误说:

The method getExpressionFactory() from the type Application refers to the missing type ExpressionFactory.

唯一可用的快速修复方法是配置构建路径。

我不知道到底应该做什么,我是否缺少任何JAR来解决这个问题?

这是我的pom.xml
