Redirect in Spring MVC

Question

Why can't I get this to work in my Controller

@RequestMapping(method = RequestMethod.POST) public String onSubmit(     Model model,     @ModelAttribute("form") Form form,     BindingResult result, HttpServletRequest request)     throws IOException, WriteException, BiffException {      if (result.hasErrors()) {         return "redirect:index.html";     }   } 

I get:

javax.servlet.ServletException: Could not resolve view with name 'redirect:index.html' in servlet with name 'dispatcher'
org.springframework.web.servlet.DispatcherServlet.render(DispatcherServlet.java:1042)
org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:798)
org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:716)
org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:644)
org.springframework.web.servlet.FrameworkServlet.doPost(FrameworkServlet.java:560)
javax.servlet.http.HttpServlet.service(HttpServlet.java:637)
javax.servlet.http.HttpServlet.service(HttpServlet.java:717)
org.netbeans.modules.web.monitor.server.MonitorFilter.doFilter(MonitorFilter.java:390)

I've got this to work before. Why not now?

Answer 1

Try this, it should work if you have configured your view resolver properly

 return "redirect:/index.html"; 

Answer 2

Also note that redirect: and forward: prefixes are handled by UrlBasedViewResolver, so you need to have at least one subclass of UrlBasedViewResolver among your view resolvers, such as InternalResourceViewResolver.
