Spring MVC简单重定向控制器示例 [英] Spring MVC Simple Redirect Controller Example

问题描述

我正在尝试比较各种框架的重定向方法.

Hi I'm trying to compare the redirect methods of various frameworks.

我已经完成了很多:

• Cakephp
• CodeIgniter
• Django
• Grails
• 铁路
• Zend框架

• Cakephp
• CodeIgniter
• Django
• Grails
• Rails
• Zend Framework

但是，我一直试图为 JSF .

However I'm stuck trying to create the simplest example possible for Spring MVC and JSF.

我想要的是一个或两个处理/index和/redirect url的控制器，其中/index只是链接到/redirect，而/redirect使用301重定向来重定向回/index.

What I want is either one or two controllers which handle the /index and /redirect urls where /index simply links to /redirect, and /redirect uses a 301 redirect to redirect back to /index.

我找到了此文档，我只是没有足够的持久性来弄清楚如何在Spring MVC中创建这个看似简单的示例.

I found this documentation, I just don't have the persistence to figure out how to create this seemingly simple example in Spring MVC.

谢谢！

推荐答案

以防万一我在JSF和SPRING MVC中玩了重定向:

Just incase I played with redirect in JSF and SPring MVC:

JSF:

  <navigation-rule>
    <from-view-id>index.xhtml</from-view-id>
    <navigation-case>
        <from-action>#{actionController.actionSubmitted}</from-action>
        <from-outcome>success</from-outcome>
        <to-view-id>index.xhtml</to-view-id>
        <redirect />
    </navigation-case>
    </navigation-rule>  

Spring-MVC以POST/REdirect/GET设计模式提交用户表单:

Spring-MVC submitting user form in POST/REdirect/GET design pattern:

@RequestMapping(value="/index.html", method=RequestMethod.GET)
public ModelAndView index(){
    ModelAndView mv = new ModelAndView("index");
    User user = new User();
        mv.addObject("user", user);
    return mv;
}

 @RequestMapping(value="/signin.html",method = RequestMethod.POST)
 public ModelAndView submit(@Valid User user){
    ModelAndView mv = new ModelAndView("redirect:index.html"); 
    System.out.println(user.getFirstName());
    return mv;
 }

希望有帮助.
