Spring MVC 3.1 RedirectAttributes无效 [英] Spring MVC 3.1 RedirectAttributes is not working
问题描述
我正在尝试在Spring MVC 3.1中实现RedirectAttributes功能 - 发布
I'm trying to implement RedirectAttributes feature in Spring MVC 3.1-Release
我正在将简单表单发送到Post URL并希望看到值I我发送重定向：
I'm sending simple form to Post URL and would like to see the the value I'm sending in redirect:
我的控制器看起来像这样：
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;
}
}
现在我的Servlet XML看起来像这样：
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/context

<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>
我的问题是在success.html视图中redirectAttributes是空的。
My problem is that in success.html view redirectAttributes is empty.
<body>
<h5>${redirectAttributes.firstName} </h5>
</body>
什么都不打印。
推荐答案
它不起作用，因为您使用ModelAndView作为返回值。
It does not work because You are using ModelAndView as a return value.
