Kotlin的弹簧有问题。当我设置@RestController并转到localhost：8080时，我可以看到“索引”。如果设置@Controller，则有
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).
我不知道为什么它不起作用。在Java中类似的代码（来自教程）工作。我的代码基于Java教程中的代码。我的App.kt
@SpringBootApplication
class Application
fun main(args: Array<String>) {
runApplication<Application>(*args)
}
SomeController
@Controller
class SomeController {
@GetMapping("/")
fun index(model: Model): String {
model["something"] = "asd"
return "index"
}
}
index.mustache：
<html>
<body>
<div>
its the {{something}}
</div>
</body>
</html>
和pom.xml

先谢谢您
使用Java，它可以正常工作-_-。相同的控制器和其他文件。
您没有在pom.xml中添加模板引擎，请添加此：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mustache</artifactId>
</dependency>
