为什么我的程序会报这个错误呢？
源码：
package com.example.test;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.bind.annotation.RequestMapping;
@RestController
public class HelloController {
@RuquestMapping (value="/hello", method= RequestMethod.GET)
public String say()
{
return "Hello Spring Boot!";
}
}
