之前所做的内容的跳转都是服务端跳转，本节学习客户端跳转的SpringMVC的客户端跳转实现
1.编写IndexController
核心代码如下

ModelAndView mav = new ModelAndView("redirect:/index");

完整代码如下：

package controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
    
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class IndexController {
    @RequestMapping("/index")
    public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception {
        ModelAndView mav = new ModelAndView("index");
        mav.addObject("message", "Hello Spring MVC");
        return mav;
    }

    @RequestMapping("/jump")
    public ModelAndView jump() {
        ModelAndView mav = new ModelAndView("redirect:/index");
        return mav;
    }
}

其他配置文件如以前所述
项目结构如下：

结构.PNG

Hello Spring MVC

其中，最初的访问路径是：

http://localhost:8080/SpringMVC_jump/jump

跳转之后的路径是:

http://localhost:8080/SpringMVC_jump/index

由此就可以看出差别了
