Spring @Controller方法返回奇怪的下载异常

Question

我在Spring MVC应用程序中返回了一个奇怪的错误。当我尝试通过@RestController方法保存用户时，浏览器似乎将该操作解释为下载应用程序的请求。有关此问题的一些信息：

• 仅当我的应用程序部署到远程服务器上时（在本地按预期工作）才会返回
• 这仅在Internet Explorer中发生

这是错误：

这是我的控制器：

@RequestMapping(value = "/saveUser/{id}", method = RequestMethod.POST)
    public String saveUser(@ModelAttribute("user") User user, @PathVariable Long id, Model model) {
        model.addAttribute("user", user);
        userRepo.save(user);
        return "success";
    }

该方法非常简单，我没有指定任何响应标头。有什么想法可能会发生这种情况吗？

UPDATE 捕获网络流量时，远程服务器上的POST方法类型为application/x-ms-application，其中Type为本地计算机上的标准text/html

Answer 1

明确将produces属性设置为"text/html"似乎已解决此问题

@RequestMapping(value = "/saveUser/{id}", produces="text/html", method = RequestMethod.POST)
