Spring MVC 3.1 RedirectAttributes is not working
Question
I'm trying to implement RedirectAttributes feature in Spring MVC 3.1-Release
I'm sending simple form to Post URL and would like to see the the value I'm sending in redirect:
my Controller looks like this:
@Controller
public class DefaultController {
@RequestMapping(value="/index.html", method=RequestMethod.GET)
public ModelAndView indexView(){
ModelAndView mv = new ModelAndView("index");
return mv;
}
@RequestMapping(value="/greetings.action", method=RequestMethod.POST)
public ModelAndView startTask(@RequestParam("firstName") String firstName,RedirectAttributes redirectAttributes){
redirectAttributes.addFlashAttribute("redirectAttributes.firstName", firstName);
ModelAndView mv = new ModelAndView(new RedirectView("success.html"));
return mv;
}
@RequestMapping(value="/success.html", method=RequestMethod.GET)
public ModelAndView successView(){
ModelAndView mv = new ModelAndView("success");
return mv;
}
}
Now my Servlet XML looks like this:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
http://www.springframework.org/schema/context

<mvc:annotation-driven/>
<context:component-scan base-package="com.vanilla.flashscope.controllers" />
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix">
<value>/</value>
</property>
<property name="suffix">
<value>.jsp</value>
</property>
</bean>
</beans>
My problem is that in success.html view redirectAttributes is empty.
<body>
<h5>${redirectAttributes.firstName} </h5>
</body>
Prints nothing.

It does not work because You are using ModelAndView as a return value.
See JIRA Issue: https://jira.springsource.org/browse/SPR-8968

It looks like you need to remove "redirectAttributes." from the key name"
Instead of:
redirectAttributes.addFlashAttribute("redirectAttributes.firstName", firstName);
Do this:
redirectAttributes.addFlashAttribute("firstName", firstName);
