Spring不提供html文件

Question

因此，我试图遵循这篇关于如何使用Spring为html文件提供服务的指南：http://spring.io/guides/gs/serving-web-content/

映射：

@RestController
public class GreetingController {

    @RequestMapping("/greeting")
    public String greeting(@RequestParam(value="name", required = false, defaultValue="World") String name, Model model) {
        model.addAttribute("name", name);
        return "greeting";
    }
}

使用@Controller引发错误：

2015-02-25 14:50:14.830 ERROR 2378 --- [nio-8080-exec-7] o.a.c.c.C.[.[.[/].[dispatcherServlet]    : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Circular view path [greeting]: would dispatch back to the current handler URL [/greeting] again. Check your ViewResolver setup! (Hint: This may be the result of an unspecified view, due to default view name generation.)] with root cause

javax.servlet.ServletException: Circular view path [greeting]: would dispatch back to the current handler URL [/greeting] again. Check your ViewResolver setup! (Hint: This may be the result of an unspecified view, due to default view name generation.)

您使用的是@restcontroller（文档），而不是@controller。

一个方便的注释，它本身用@Controller和@ResponseBody注释。

和@responsebody只返回调用方方法返回的任何内容，在您的情况下，字符串greeting。

ViewResolver有许多实现可供选择，而Spring本身并不是对您应该使用哪些实现固执己见。而Spring Boot则根据在类路径和应用程序上下文中找到的内容为您安装一个或两个

因此，可能在依赖项中缺少了一些东西。是否配置了spring-boot-starter-thymeleaf依赖项？
