Spring Boot MVC：URL未发布，但显示在引导日志中

Question

我只是用Spring Boot（和Groovy）启动了一个非常简单的Spring MVC，我不能让我的控制器正确地路由，例如：

package net.kedare

import org.springframework.boot.SpringApplication
import org.springframework.boot.autoconfigure.SpringBootApplication
import org.springframework.stereotype.Controller
import org.springframework.web.bind.annotation.RequestMapping
import org.springframework.web.bind.annotation.RequestMethod

@SpringBootApplication
class SpringLedControllerApplication {

    static void main(String[] args) {
        SpringApplication.run SpringLedControllerApplication, args
    }
}

@Controller
@RequestMapping("/")
class SpringLedController {

    @RequestMapping(method=RequestMethod.GET)
    public String index() {
        return "Hello"
    }

}

它出现在引导日志中：2016-01-23 14:09:28.588 INFO 57995---[main]S.W.S.M.M.A.RequestMappingHandlerMapping：映射“{[/],methods=[GET]}”到公共java.lang.String net.kedare.springledController.index（）

Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

在pom.xml中添加此依赖关系：

  <dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-thymeleaf</artifactId>
 </dependency>
