Spring Boot Controller返回语句创建循环视图路径

@Controller
@RequestMapping("front")
public class FrontendController {

    @GetMapping("/hello")
    public String hello(){
        System.out.println("porttest");

        return "hello";
    }
}

going tohttp://localhost:8080/front/hello gives whitelabel error and

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

如果我将返回值从“ hello”更改为其他任何值，那么我会收到带有其他消息的白色标签

No message available

为什么return语句的值这样做？

im trying to return the hello.html page to browser
