控制器

package javanaina.hello;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class HelloController {
    @RequestMapping("/hello")
    public String sayHi() {
        return "Hi";
    }
}

这是一个简单的应用程序，应该在localhost上给予一个错误页面，因为只有main函数被写入，但它给了我这个错误，我不明白为什么。
