我的spring boot项目出现了一些错误，我找不到问题所在，有人能帮我吗，以下是我的日志：

        </plugins>

</project>

这是我的控制器：

package com.qi.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.servlet.ModelAndView;

import com.qi.models.AppUsers;
import com.qi.models.UsersRepo;

@Controller
public class MainController {
    @Autowired
    UsersRepo appRepo;

    @RequestMapping("/")
    public ModelAndView doHome() {
        ModelAndView mv = new ModelAndView("index");
        mv.addObject("lists",appRepo.findAll());
        return mv;
    }
    @RequestMapping( value = "/save", method = RequestMethod.POST)
    public ModelAndView doSave(@RequestParam("id") String id, @RequestParam("firstname") String firstName, @RequestParam("lastname") String lastName) {
        ModelAndView mv = new ModelAndView("redirect:/");
        AppUsers users;
        if (!id.isEmpty()) {
            users = (AppUsers)appRepo.findById(Integer.parseInt(id)).orElse(null);
        } else {
            users = new AppUsers();
        }
        users.setFirstName(firstName);
        users.setLastName(lastName);
        appRepo.save(users);
        return mv;
    }
    @RequestMapping( value = "/view{id}", method = RequestMethod.GET)
    public ModelAndView doView(@PathVariable("id") int id) {
        ModelAndView mv = new ModelAndView("view");
        mv.addObject("lists", appRepo.findById(id).get());
        return mv;
    }
    @RequestMapping( value = "/delete{id}", method = RequestMethod.GET)
    public ModelAndView doDelete(@PathVariable("id") int id) {
        ModelAndView mv = new ModelAndView("redirect:/");
        appRepo.deleteById(id);
        return mv;
    }
    @RequestMapping( value = "/edit{id}", method = RequestMethod.GET)
    public ModelAndView doEdit(@PathVariable("id") int id) {
        ModelAndView mv = new ModelAndView("edit");
        mv.addObject("lists", appRepo.findById(id).get());
        return mv;
    }

}

这是我的模型：

package com.qi.models;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;

import org.springframework.beans.factory.annotation.Autowired;

@Entity
@Table(name = "appusers")
public class AppUsers {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    public int id;

    @Column(name = "firstname")
    public String firstName;

    @Column(name = "lastname")
    public String lastName;

    public AppUsers() {

    }

    public AppUsers(String firstName, String lastName) {
        this.firstName = firstName;
        this.lastName = lastName;
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getFirstName() {
        return firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    public String getLastName() {
        return lastName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

}

这是我的存储库：

package com.qi.models;

import org.springframework.data.repository.CrudRepository;

public interface UsersRepo extends CrudRepository<AppUsers, Integer>{

}

这是application.properties

spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp
spring.datasource.driver-class-name=com.mysql.jdbc.Driver 
spring.datasource.url=jdbc:mysql://localhost:3306/qi 
spring.datasource.username=root 
spring.datasource.password= 
spring.jpa.hibernate.ddl-auto= update

# spring.jpa.generate-ddl=true

server.port=8097

这是主要课程：

package com.qi;

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

@SpringBootApplication
public class MySpringBoot1Application {

    public static void main(String[] args) {
        SpringApplication.run(MySpringBoot1Application.class, args);
    }

}
