Glassfish 3.1.2.2上的'ExceptionHandlerFactory未正确配置'

我正在尝试通过ExceptionHandler处理未捕获的异常。遵循JSF2完整参考中的代码，我已经为我的处理程序创建了类。但是当我部署我的应用程序时，它会抛出下一个stackTrace：

这是我的faces-config.xml：

<factory>
    <exception-handler-factory>
        exception.ExceptionHandlerFactory
    </exception-handler-factory>
</factory>

ExceptionHandlerFactory.java 

public class ExceptionHandlerFactory extends javax.faces.context.ExceptionHandlerFactory {

private transient Logger logger = Logger.getLogger(this.getClass().getName());
private ExceptionHandlerFactory parent;

public ExceptionHandlerFactory(ExceptionHandlerFactory parent) {
    this.parent = parent;
}

@Override
public ExceptionHandler getExceptionHandler() {
    ExceptionHandler result = parent.getExceptionHandler();
    result = new CustomExceptionHandler(result);
    return result;
}

}

CustomExceptionHandler.java 

public class CustomExceptionHandler extends ExceptionHandlerWrapper {

private ExceptionHandler parent;

public CustomExceptionHandler(ExceptionHandler parent) {
    this.parent = parent;
}

@Override
public ExceptionHandler getWrapped() {
    return this.parent;
}

@Override
public void handle() throws FacesException {
    for (Iterator<ExceptionQueuedEvent> i =
            getUnhandledExceptionQueuedEvents().iterator();
            i.hasNext();) {
        ExceptionQueuedEvent event = i.next();
        ExceptionQueuedEventContext context =
                (ExceptionQueuedEventContext) event.getSource();
        Throwable t = context.getException();

        if (t instanceof ViewExpiredException) {
            ViewExpiredException vee = (ViewExpiredException) t;
            FacesContext fc = FacesContext.getCurrentInstance();
            NavigationHandler nav =
                    fc.getApplication().getNavigationHandler();
            try {

                fc.getExternalContext().
                        getFlash().put("currentViewId",
                        vee.getViewId());
                nav.handleNavigation(fc, null, "/login?faces-redirect=true");
                fc.renderResponse();
            } finally {
                i.remove();
            }
        } 
    }

    getWrapped().handle();
}
}

服务器是Glassfish 3.1.2.2。

当我得到ViewExpiredException时，我需要一些逻辑。我错过了什么？ 在此先感谢!!!!

修改

正如@BalusC指出的那样，我改变了我的工厂类名，所以这是我的CustomExceptionHandlerFactory.java：

public class CustomExceptionHandlerFactory extends ExceptionHandlerFactory {

    private ExceptionHandlerFactory parent;

    public CustomExceptionHandlerFactory(ExceptionHandlerFactory parent) {
        this.parent = parent;
    }

    @Override
    public ExceptionHandler getExceptionHandler() {
        ExceptionHandler result = parent.getExceptionHandler();
        result = new CustomExceptionHandler(result);
        return result;
    }
}

和我的faces-config.xml：

<factory>
    <exception-handler-factory>
        com.exception.CustomExceptionHandlerFactory
    </exception-handler-factory>
</factory>

我希望这对有这个愚蠢问题的人有所帮助。

答案 0 :(得分：5)

您的错误在于，您出于某些不明原因重复使用与现有API类相同的类名，并将其混淆在代码中。

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

最好将您的课程重命名为CustomExceptionHandlerFactory之类的独特内容。
