java - Spring MVC validator annotation + custom validation -


I am working on Spring MVC application, where I need verification based on Spring MVC videor. For this I added an annotation to the class and setup controller in the first stage and it works fine and now I need to implement the custom verifier to execute complex arguments, but I want to use the existing annotation and just I would like to add additional checks.

My user class: 

  public class user {@NotEmpty private string name; @ Private entry is not logged; // should be unique}

My validator: 

  @Component public class UserValidator implementer verifier {@Autowired Private UserDAO userDAO; Support for @ Override Public Boolean (class

My Controller: 

  @ Controller Public Class UserController {@Autowired Private UserValidator validator; @InitBinder Secure Zero InitBender (Last WebDetBender Binder) {binder.setValidator (validator); } @RequestMapping (Value = "/ save") Public ModelAndView (@ Valid @ModelAttribute ("User") End User User, Binding Results Results) {if (result.hasErrors ()) {// handle error} else {// save user}}}

So, is it possible to use custom medicine and annotation? And if yes, how are you?

I know this is an old question, but, for Google ...

You should use addValidators instead of setValidator . Like the following:

@InitBinder Secure Zero InitBender (Last WebDetBender Binder) {binder.addValidators (yourCustomValidator, anotherValidatorOfYours); }

PS: addValidators accepts more than one parameter (oval)

If you select org.springframework.validation Check the source. Data Binder You will see: 

  Public class database banner applies Property Editor Registry, TypeConverter {.... Public Zero Set Validator (Accredited Verifier) ​​{Achievement Validator}; This.validators.clear (); This.validators.add (validator); } Public Zero addValidators (Validator ... validators) {assertValidators (validators); This.validators.addAll (Arrays.asList (Authenticators)); }.}}

As you see setValidator clears the current (default) verifier, so the @valid annotation Expected as will not work.

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ
