java - 错误 : ConfigurationException- Factory 'javax.faces.context.ExceptionHandlerFactory' was not configured properly

Question

我在 Jetty 8 上运行时一直遇到上述错误。我已将 Maven 依赖项用于 jsf-api-2.1.2、jsf-impl-2.1.2 和 Spring security。

用于 Jetty 8 的命令:java -jar start.jar

在 faces-config.xml 中

<factory>
  <exception-handler-factory>_PACKAGE_.exceptionhandler.ViewExpiredExceptionExceptionHandlerFactory</exception-handler-factory>

在ViewExpiredExceptionExceptionHandlerFactory.java

    public class ViewExpiredExceptionExceptionHandlerFactory extends ExceptionHandlerFactory {
 
    private ExceptionHandlerFactory parent;
 
    public ViewExpiredExceptionExceptionHandlerFactory(ExceptionHandlerFactory parent) {
        this.parent = parent;
    }
 
    @Override
    public ExceptionHandler getExceptionHandler() {
        ExceptionHandler result = parent.getExceptionHandler();
        result = new ViewExpiredExceptionExceptionHandler(result);
        return result;
    }
}

以及 Jetty 8 中的 Stacktrace

我不知道发生了什么，但是类 ViewExpiredExceptionExceptionHandlerFactory 存在。仅供引用，我在 web.xml 中也有 com.sun.faces.config.ConfigureListener、ContextLoaderListender 和 RequestContextListner，如果有帮助的话。

Answer 1

您的错误是您出于某种不明原因重用了与现有 API 类相同的类名，并在代码中混淆了它们。

父构造函数参数(和局部变量)必须是 javax.faces.context.ExceptionHandlerFactory 类型，而不是您的 exception.ExceptionHandlerFactory 类型。这种错误的类型导致 JSF 无法调用构造函数，因此 - 而不是 self 解释 - InstantiationException(无法实例化)。

最好将您的类重命名为独特的名称，例如 CustomExceptionHandlerFactory。
