Question

我希望在INVOKE_APPLICATION阶段获得特定的自定义异常后继续使用JSF：RENDER_RESPONSE（JSF生命周期的最后阶段）。

对于以下操作，所有六个JSF生命周期阶段都运行：

public void save(String actionID) throws Exception
{
}

我在日志中得到的是：

 START PHASE RESTORE_VIEW 1
 END PHASE RESTORE_VIEW 1
 START PHASE APPLY_REQUEST_VALUES 2
 END PHASE APPLY_REQUEST_VALUES 2
 START PHASE PROCESS_VALIDATIONS 3
 END PHASE PROCESS_VALIDATIONS 3
 START PHASE UPDATE_MODEL_VALUES 4
 END PHASE UPDATE_MODEL_VALUES 4
 START PHASE INVOKE_APPLICATION 5
 END PHASE INVOKE_APPLICATION 5
 START PHASE RENDER_RESPONSE 6
 END PHASE RENDER_RESPONSE 6

但是对于以下操作（操作抛出异常）：

public void save(String actionID) throws Exception
{
    throw new FieldMissingException("LLLL");
}

我得到了：

START PHASE RESTORE_VIEW 1
 END PHASE RESTORE_VIEW 1
 START PHASE APPLY_REQUEST_VALUES 2
 END PHASE APPLY_REQUEST_VALUES 2
 START PHASE PROCESS_VALIDATIONS 3
 END PHASE PROCESS_VALIDATIONS 3
 START PHASE UPDATE_MODEL_VALUES 4
 END PHASE UPDATE_MODEL_VALUES 4
 START PHASE INVOKE_APPLICATION 5

END PHASE INVOKE_APPLICATION 5

渲染响应阶段未执行。如何在申请阶段获得异常后进入下一阶段。

为了全局处理Exception，我还创建了ExceptionHandlerFactory和ExceptionHandler exceptionHandler-link。

@Override
public void handle()
    throws FacesException
{
    for (final Iterator<ExceptionQueuedEvent> it = getUnhandledExceptionQueuedEvents().iterator(); it.hasNext();) {
        Throwable t = it.next().getContext().getException();
        while ((t instanceof FacesException) && t.getCause() != null) {
            t = t.getCause();
        }
        if (t instanceof FieldMissingException) {
            // -->  What should I write here to stop propogation of custom exception to next phase  
            // final FacesContext facesContext = FacesContext.getCurrentInstance();
            // facesContext.responseComplete();
        }
    }
    getWrapped().handle();
}
