why this exception is coming on entering invalid email rather than validation has to be performed.
public class BindException extends Exception implements BindingResult. Thrown when binding errors are considered fatal. Implements the BindingResult interface (and its super-interface Errors ) to allow for the direct analysis of binding errors. As of Spring 2.0, this is a special-purpose class.
BindException is an exception that is thrown when there is an error caused in binding when an application tries to bind a socket to a local address and port.
BindingResult holds the result of a validation and binding and contains errors that may have occurred. The BindingResult must come right after the model object that is validated or else Spring fails to validate the object and throws an exception.
In your controller's addUser
method, your BindingResult
needs to be immediately after the bean:
public String addUser(@Valid UserBean userBean, BindingResult bindingResult,
Model model, RedirectAttributes redirectAttrs) {
...
}
