小弟刚学习ssm,整合时候遇到困难，始终没有头绪，望各位大佬指点迷津，真诚地感谢

package top.airprogram.controller;


import javax.servlet.http.HttpServletRequest;

@Controller

public class UserController {


@Autowired

拦截器
package top.airprogram.interceptor;

public class SpringMvcInterceptor implements HandlerInterceptor {
@Override //请求往controller发之前执行，false则请求打住不发往Controller，
// 只有返回true postHandle方法和afterCompletion方法才会执行，请求才会发到controller
public boolean preHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o) throws Exception {
return true;
}

@Override//本方法Controller执行后执行
public void postHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, ModelAndView modelAndView) throws Exception {
System.out.println("请求执行了");

}

@Override
public void afterCompletion(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, Exception e) throws Exception {
System.out.println("请求处理完了");
}
}

service层
接口
package top.airprogram.service;

import org.springframework.stereotype.Service;
import top.airprogram.entity.student;

public interface StuService {
int createStu(student student);
}


实现类
package top.airprogram.service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import top.airprogram.entity.student;
import top.airprogram.dao.*;


@Service("stuserviceimpl") //标注service层并命名
public class StuServiceImpl implements StuService {
@Autowired
private studentMapper studentMapper;


@Override
public int createStu(student student) {
studentMapper.insertSelective(student);
return 0;
}
}

字数限制，dao,entity包没有贴出来，应该不关他们事吧，嘎嘎，然后基于以上一直出现以下异常，网上多是说缺注解或者包路径错，小弟不才找不出来，希望各位大牛教教谢谢。。。
.BeanCreationException: Error creating bean with name 'stuserviceimpl': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private top.airprogram.dao.studentMapper top.airprogram.service.StuServiceImpl.studentMapper; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [top.airprogram.dao.studentMapper] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

[qq_41228556]

studentMapper 是不是没有写注解@Repository,这个类提示有问题

[村里老人组的希望]

加上也错

[oO临时工Oo]

应该是你有个类叫studentMapper，这个类上没有加@Service("studentMapper")
