Description:

Field cate in cn.edu.neu.hellospringboot.controller.HelloController required a bean of type 'cn.edu.neu.hellospringboot.model.Categray' that could not be found.

启动代码截图如下：
package cn.edu.neu.hellospringboot.controller;

import cn.edu.neu.hellospringboot.config.MyService;
import cn.edu.neu.hellospringboot.model.Categray;
import cn.edu.neu.hellospringboot.model.Person;
import cn.edu.neu.hellospringboot.model.User;
import cn.edu.neu.hellospringboot.service.HelloService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class HelloController {
@Autowired
public User user;
@Autowired
public Categray cate;

@Autowired
public Person person;
@Autowired
public HelloService service;

@Autowired
public MyService myService;

@RequestMapping("/")
public  String hello(){
    String result=service.getData();

    myService.testMyservice();

    System.out.println(user);
   // System.out.println(cate);
    System.out.println(person);
    return result+user.getUser_name();

// return "Hello SpringBoot！";
}
}

求解答！

categray这个类是Javabean吧，你肯定不能用autowired注解注入，因为spring上下文压根就没有这个bean，所以报错了，你看看报错，很明确的。
对于javabean，通常是new这个对象
