@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

为什么return语句的值这样做?
