java - Spring Boot Controller 重定向不起作用

Question

我正在尝试使用 Spring 引导的快速原型(prototype)。

我有以下 Controller 代码减去导入

@EnableAutoConfiguration
@RestController
@Controller
public class IndexController{
    @RequestMapping(value = "/")
    public ModelAndView firstPage(HttpServletRequest request, HttpServletResponse response){
        ModelAndView mv = new ModelAndView("index");
        mv.addObject("message", Calendar.getInstance().getTime().toString());
        return mv;
    }
    @RequestMapping(value="/gotoNextPage",method = RequestMethod.GET)
    public  ModelAndView gotoNextPage(HttpServletRequest request, HttpServletResponse response){
        System.out.println("Inside gotoNextPage!!!!!!");
        ModelAndView mv = new ModelAndView("redirect:nextpage");
        mv.addObject("message", "next page");
        return mv;
    }
}

在我的 HTML 中，我调用了/gotoNextPage，在我的服务器中，我看到了 Inside gotoNextPage!!!!打印语句。但是，nextPage 不会加载。如果我不使用重定向并输入 http://localhost:8080/gotoNextPage ，HTML 内容加载正常。此外，index.html 也可以正常加载

我正在使用 spring boot mvc、thymeleaf、angularjs

请帮忙。

提前致谢。

我会尝试简化使用 Model 的方法并返回一个简单的 String:

@RequestMapping(value="/gotoNextPage",method = RequestMethod.GET)
public String gotoNextPage(Model model){
    LOG.debug("Inside gotoNextPage!!!!!!");
    model.addAttribute("message", "next page");
    return "redirect:nextpage.html";
}
