[英]Spring MVC 3.1 RedirectAttributes is not working
I'm trying to implement RedirectAttributes feature in Spring MVC 3.1-Release 我正在尝试在Spring MVC 3.1-Release中实现RedirectAttributes功能
I'm sending simple form to Post URL and would like to see the the value I'm sending in redirect: 我正在发送简单的表单到Post URL,并希望看到我在重定向中发送的值:
my Controller looks like this: 我的控制器看起来像这样:
@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: 现在我的Servlet XML看起来像这样:
<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"

xsi:schemaLocation="

<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. 我的问题是,在success.html视图中,redirectAttributes为空。
<body>
<h5>${redirectAttributes.firstName} </h5>
</body>
Prints nothing. 什么都不打印。
It does not work because You are using ModelAndView as a return value. 它不起作用,因为您使用ModelAndView作为返回值。
See JIRA Issue: https://jira.springsource.org/browse/SPR-8968 请参阅JIRA问题: https : //jira.springsource.org/browse/SPR-8968
It looks like you need to remove "redirectAttributes." 看起来您需要删除“redirectAttributes”。 from the key name" 从关键名称“
Instead of: 代替:
redirectAttributes.addFlashAttribute("redirectAttributes.firstName", firstName);
Do this: 做这个:
redirectAttributes.addFlashAttribute("firstName", firstName);
