之前一直启动都没有问题，今天突然发现启动不了

然后我把启动的位置改成@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)

package com.mall.shopping.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;

/*@SpringBootApplication*/
@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

}

然后会报新的错：

到现在没找到新错误的原因还是在报找不到dao的错误。

实体类代码：

controller代码：

package com.mall.shopping.demo.controller;

import com.mall.shopping.demo.services.UserService;
import com.mall.shopping.demo.vo.Huser;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.Iterator;
import java.util.List;

@Controller
public class UserController {
    @Autowired
    private UserService userService;

    @RequestMapping("/tiao")
    public ModelAndView zhuan()
    {
        ModelAndView modelAndView = new ModelAndView("loginindex");
        return modelAndView;
    }

    @RequestMapping("/tiao1")
    public ModelAndView zhuan1()
    {
        ModelAndView modelAndView = new ModelAndView("adminindex");
        return modelAndView;
    }


    @RequestMapping("/Userlogin")
    public String userlogin(HttpServletRequest request, HttpServletResponse response)
    {
        String username = (String) request.getParameter("username");
        String userpwd = (String)request.getParameter("userpwd");
        List<Huser> huser = userService.userlogin();
        Iterator iter = huser.iterator();
        while(iter.hasNext()){
            Huser ha = (Huser) iter.next();
            if(username.equals(ha.getHuser()))
            {
                if(userpwd.equals(ha.getHpwd()))
                {
                    return "redirect:/tiao1";
                }
                else
                {
                    return "redirect:/tiao";
                }
            }
        }

        return "redirect:/tiao";
    }
