Validation in MultiActionController
This example just works!
public class EventValidator implements Validator { public boolean supports(Class clazz) { //return EventDO.class.equals(clazz); return clazz.equals(EventDO.class); } public void validate(Object obj, Errors e) { ValidationUtils.rejectIfEmpty(e, "title","error_mandatory","title cannnot be null"); } } ---- public class EventController extends MultiActionController{ BindingResult errors; //Declaring errors as instance variable to catch error //the last param acts as a command object public ModelAndView submitEvent(HttpServletRequest request, HttpServletResponse response, EventDO event) throws Exception { validate(event); if (errors.hasErrors()) { return new ModelAndView("events/events",errors.getModel()); } return new ModelAndView("events/events"); } public void validate(Object command) { ValidationUtils.invokeValidator(new EventValidator(), command, errors); } @Override protected void bind(HttpServletRequest request, Object command) throws Exception { ServletRequestDataBinder binder = createBinder(request, command); binder.bind(request); errors = binder.getBindingResult(); } } ---- <%@ page contentType="text/html;charset=UTF-8" %> <%@ taglib uri="http://www.springframework.org/tags/form" prefix="form"%> <html> <body> <form:form method="post" name="suggestionsController" action="events.htm?method=submitEvent"> <form:errors path="title"/> <input name="title"/> </form:form> </body> </html> ---- <bean id="eventController" class="com.iranoz.controller.EventController"> <property name="methodNameResolver" ref="paramResolver"/> <property name="validators" ref="eventValidator"/> </bean>
