java Kotlin+spring+mustache@Controller不工作（白标签错误页面），但@RestController工作

科特林的弹簧有问题。当我设置@RestController并转到localhost:8080时，我可以看到“index”。如果我设置@Controller，我有

Whitelabel Error Page

This application has no configured error view, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).

我不知道它为什么不起作用。在java中，类似的代码（来自教程）正在运行。我的代码基于java教程中的代码。我的应用。kt

@SpringBootApplication
class Application

fun main(args: Array<String>) {
    runApplication<Application>(*args)
}

某个控制器

@Controller
class SomeController {

    @GetMapping("/")
    fun index(model: Model): String {
        model["something"] = "asd"

        return "index"
    }
}

索引。胡子：

<html>
<body>
<div>
    its the {{something}}
</div>
</body>
</html>

还有pom。xml
