Usage

From source file:de.iew.web.utils.ValidatingFormAuthenticationFilter.java

@Override
public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response)
        throws AuthenticationException {
    LoginForm loginForm = new LoginForm();

    /*//from w w  w.j a  v  a  2  s .  c o  m
    Validiere zuerst die Logindaten. Da wir hier in einem Filter sind,
    mssen wir die Validierung per Hand vornehmen. Das Validierungsergebnis
    wird dann im Fehlerfall durch eine Exception mitgeteilt.
            
    @see <a href="http://static.springsource.org/spring/docs/3.0.x/reference/validation.html">http://static.springsource.org/spring/docs/3.0.x/reference/validation.html</a>
    */
    DataBinder binder = new DataBinder(loginForm);
    binder.setValidator(this.validator);

    MutablePropertyValues mutablePropertyValues = new MutablePropertyValues(request.getParameterMap());
    binder.bind(mutablePropertyValues);
    binder.validate();

    BindingResult results = binder.getBindingResult();

    if (results.hasErrors()) {

    }
