Logging exceptions with spring web flow -

-

Hi,

I'm a newbie with Spring Web Flow I'm trying to figure out The easiest way to log exception is within a flow file. There is a tag called Exception Handler but I can not find any documents about logging exceptions. I know that third-party libraries exception ( spring , hibernating ) are logged in, but I want to handle the exception and I want to make my own log entries I am

Exception Handling on Controlling Base

to @ExceptionHandler 
  @Controller public square ExceptionHandlingController {@ExceptionHandler (Exception.class) public ModelAndView getExceptionPage (exception e, HttpServletRequest request) {// catch all exceptions / / here If anything, with the exception object (IsAjax (request)) {// exception that comes to Ajax requests ModelAndView model = new ModelAndView ( "forward: / app / webExceptionHandler / ajaxErrorRedirectPage"); Model.addObject ("exception", exception); Model.addObject ("url", req.getRequestURL ()); Model.setViewName ("Error"); Return model; } Else {// If there is an exception for all non-ajax request model and visual model = New ModelAndView ("forward: / app / webExceptionHandler / nonAjaxErrorRedirectPage"); Model.addObject ("exception", exception); Model.addObject ("url", req.getRequestURL ()); Model.setViewName ("Error"); Return model; }} @ExceptionHandler ({SQLException.class, DataAccessException.class}) public String databaseError () {// specific exception SQLException return "databaseError" catches; } Private Stable Boolean is AJAX (HTPSArlet Request) {Return "XMLHttpRequest" .equals (request.getHeader ("X-requested-with")); }}   
  Global Exception Handling   
 Using  @ControllerAdvice  Class  
 A controller's advice allows you to use the same exception handling techniques, but does not apply them to the whole application, not just for a different controller. You supported three types of annotations can think of them powered interceptor as  
 annotated with any class  @ControllerAdvice  becomes a controller-advised and method :.  
  @ControllerAdvice class GlobalControllerExceptionHandler {@ExceptionHandler (DataIntegrityViolationException.class) public void handleConflict () nothing {//}}   
 Please more info for.

ios - Adding an SKSpriteNode to SKScene from a child SKSpriteNode -

-
I have a SKScene where I am adding an SKSpriteNode I have subclassed the SKSpriteNode class to create this node. In the subclass I am defining some SKActions on Sprite. What do I want to do when the end of this phantom ends the SKAction sequence, then I add a new Prayer node to this scene. How is this possible. The following code is mine: The code for the sequence is that I'm running on the Scansprinitode subclass (TEMissileNode): - SKAction * moveDown = [SKAction moveToY: Self.position.y - 20 Duration: 0.2]; SKAction * animation = [SKAction animateWithTextures: textures timePerFrame: time / 7]; SKAction * moveMissileProjectile = [SKAction Moving: Pointoffscreen Term: Time]; SKAction * group = [SKAction group: @ [animation, movement projectile]]; SKAction * Sequence = [SKAction Sequence: @ [Hilldown, Group, [SKAction removalFromParent]]]; [Self run action: sequence]; From the main scene, I call those actions that execute these tasks TEMissileNode * missile = [tmissil...

Matlab transpose a table vector -

-
An embarrassing simple question seems to be, but how can I move a Matlab table vector? aTableT = aTable '; I tried a standard syntax for the simple interaction of a line vector to a line vector aTable : ATableT = reshape (aTable, 1, Height (aTable)); and aTableT = rot90 (aTable); According to the head, the last time table should work for table, see. However, I get this error code: Error type in using table / permit (line 396) Undefined function 'permute' for the input arguments. Error in rot 90 (line 29) b = magnitude (b, [2 1 3: ndims (a)]); NB: fliplr is not useful either pretty sure I have covered clear angles - any ideas? Thanks! Try changing your table into an array, move it, then back to a table In other words, try doing this: aTableArray = table2array (aTable); ATableT = array 2table (aTableArray. '); I have also read the document for rot90 , and it says that rot90 is definitely working for tables Do, and I find you...

c# - Textbox not clickable but editable -

-
I have a small form with 10 text boxes, I have set them in the correct tab order. I want them on my tab service I was wondering if there is a way to set the text box so that they can be selected for editing until they are tabbed. That is ... I do not want the end user to edit the text box to click on them, I just want to make them editable through tabu. this should do the trick public partial category poor text box: Text Box {Safe Override Zero WndProc (Ref: Message Message) {if (m.msg == (Int) WM.LBUTTONDOWN) {Return; // mount down events} base.WndProc (ref m); }} Window message enum can be found. How to do this without anherizing: text box : class EatMouseDown: netwindows {safe override zero WndProc (ref message message) {if (m.msg == (int) WM.LBUTTONDOWN) {return; } Base.WandProc (Ref M); }} Safe Override Zero Onload (EventEurge E) {base.OnLoad (e); How to do this without any part: left a clean part, whatever is important, this can be a buggy but it works R...
