请问这个问题怎么解决？java.lang.IllegalStateException: Failed to load ApplicationContext

usercontroll类

package com.example.springboot05.controller;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.*;
public class userControll {
//@RestController注解能够使项目支持Rest
@RestController
@RequestMapping(value = “/springboot”)
public class UserController {
//这里使用@RequestMapping注解表示该方法对应的二级上下文路径
@RequestMapping(value = “/getUserByGet”, method = RequestMethod.GET)
public String getUserByGet(@RequestParam(value = “userName”) String userName) {
return "Hello " + userName;
}
//通过RequestMethod.POST表示请求需要时POST方式
@RequestMapping(value = “/getUserByPost”, method = RequestMethod.POST)
public String getUserByPost(@RequestParam(value = “userName”) String userName) {
return "Hello " + userName;
}
// //在入参设置@RequestBody注解表示接收整个报文体，这里主要用在接收整个POST请求中的json报文体，
// //目前主流的请求报文也都是JSON格式了，使用该注解就能够获取整个JSON报文体作为入参，使用JSON解析工具解析后获取具体参数
// @RequestMapping(value = “/getUserByJson”, method = RequestMethod.POST)
// public String getUserByJson(@RequestBody String data) {
// return "Json is " + data;
// }
}
}

错误提示：
