spring里面有bean，但是@Autowrite注入不进去

caontroller层

@RequestMapping("/video")
@RestController
public class VedioController {
//    @Resource(name= "videoServiceImpl")
    @Autowired
    private VideoService videoService;

    @RequestMapping("/list")
    @LogAnnotation(module = "视频",operation = "获取视频列表")
    private Result getVedioList(@RequestBody QueryParams queryParams){
        DataVo vedioList = videoService.getVedioList(queryParams);
        return Result.success(vedioList);
    }

    @RequestMapping("/add")
    @LogAnnotation(module = "视频",operation = "获取视频列表")
    private Result addVeedio(@RequestBody VideoParams videoParams){
        Result result = videoService.addVedio(videoParams);
        return Result.success(result);
    }
    @RequestMapping("/del")
    @LogAnnotation(module = "视频",operation = "获取视频列表")
    private Result delVedio(@RequestParam Integer id){
        videoService.delVedio(id);
        return Result.success(null);
    }
    @RequestMapping("/edit")
    @LogAnnotation(module = "视频",operation = "获取视频列表")
    private Result editVedio(@RequestBody VideoParams videoParams){
        return Result.success(videoService.editVedio(videoParams));
    }

}

service层

@Service
@Transactional
public class VideoServiceImpl implements VideoService {

    @Autowired
    private VideoMapper videoMapper;
    @Autowired
    private TeacherService teacherService;
    @Autowired
    private DataVo dataVo;

    @Override
    public DataVo getVedioList(QueryParams queryParams) {
        Page

这个是打印spring里面的bean名称，红框中的bean就是注入不进去的bean

最后问题发现是因为controller中的方法都是private，然后就改成public就没有问题了
最后把打印bean的代码

 @Bean
    public CommandLineRunner commandLineRunner(ApplicationContext ctx) {
        return args -> {

            System.out.println("Let's inspect the beans provided by Spring Boot:");

            String[] beanNames = ctx.getBeanDefinitionNames();
            Arrays.sort(beanNames);
            for (String beanName : beanNames) {
                System.out.println(beanName);
            }

        };
    }
