JSF（jboss - 2.2.6），AS Wildfly 8.1.0，Deltaspike 1.0.3

会话过期后，按下按钮（ajax调用）。问题是抛出NullPointerExcepti而不是ViewExpiredException。

有一个ExceptionHandlerWrraper。

public class CoreExceptionHandlerWrapper extends ExceptionHandlerWrapper {

private final BeanManager beanManager;

private final ExceptionHandler wrapped;

public CoreExceptionHandlerWrapper(final ExceptionHandler wrapped) {
    this.wrapped = wrapped;
    this.beanManager = BeanManagerProvider.getInstance().getBeanManager();
}

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

@Override
public void handle() throws FacesException {
    FacesContext context = FacesContext.getCurrentInstance();
    Iterator<ExceptionQueuedEvent> it = getUnhandledExceptionQueuedEvents().iterator();
    while (it.hasNext()) {
        try {
            ExceptionQueuedEvent evt = it.next();
            ExceptionToCatchEvent etce = null;

            if (context == null || !context.getPartialViewContext().isAjaxRequest()) {
                etce = new ExceptionToCatchEvent(evt.getContext().getException(), WebRequestLiteral.INSTANCE);
            } else {
                etce = new ExceptionToCatchEvent(evt.getContext().getException(), FacesRequestLiteral.INSTANCE);
            }
            beanManager.fireEvent(etce);
        } finally {
            it.remove();
        }

       }
    getWrapped().handle();
    }  
}

FacesException由：

处理 
void showFacesMessage(@Handles @FacesRequest ExceptionEvent<Throwable> evt, FacesContext fc) {
    Throwable exception = evt.getException();

    persistException(evt.getException());
    if(exception instanceof ViewExpiredException) {
        NavigationHandler nav = fc.getApplication().getNavigationHandler();
        try {
            nav.handleNavigation(fc, null, "/login.xhtml?faces-redirect=true");//?faces-redirect=true&amp;exceptionMessage=" + exceptionMessage
        } catch(Exception e) {System.out.println(e.toString());}
        fc.renderResponse();
    }

这是堆栈：

1 个答案:

答案 0 :(得分：0)

调试后，我能够找到NullPointerException的主要问题。视图中的组件使用绑定属性引用bean中的javax.faces.component.UIInput对象（javax.faces.view.ViewScoped）。当会话到期并且ajax调用被maded并创建（两次）bean的新实例时。我不知道为什么UIInput强制创建bean，但这是另一个话题。在使用@PostConstruct注释的方法中，有一个抛出NullPointerException的代码。如果在抛出预期的ViewExpiredException之后正确处理此异常。
