创建名称为'loginRepository'的bean时出错：初始化方法的调用失败；嵌套异常

Question

这是我的代码：

springboot类

   package com.angularjs.app.controller;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.web.bind.annotation.RestController;


//@RestController
//@EnableAutoConfiguration
@SpringBootApplication
public class Application extends SpringBootServletInitializer{

     protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
            return builder.sources(Application.class);
        }

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

}

控制器

    package com.angularjs.app.controller;

import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import org.springframework.web.bind.annotation.RequestBody;
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.bind.annotation.RestController;
import org.springframework.web.servlet.ModelAndView;

import com.angularjs.app.message.Response;
import com.angularjs.app.model.LoginVO;
import com.angularjs.app.repo.LoginRepository;
//@Configuration
//@ComponentScan
//@EnableAutoConfiguration
@RestController
@EnableJpaRepositories("com.angularjs.app.repo")
public class LoginController {

    //@Autowired
    LoginRepository loginRepository;

    @RequestMapping("/findbyusername")
    public Response findByLastName(@RequestParam("username") String username) {

        LoginVO userDetails = loginRepository.findByUsername(username);

        return new Response("Done", userDetails);
    }

    @RequestMapping("/")
    ModelAndView home(ModelAndView modelAndView) {

        modelAndView.setViewName("home");

        return modelAndView;
    }

    @RequestMapping(value = "/postuserdetails", method = RequestMethod.POST)
    public void postCustomer(@RequestBody LoginVO loginVo) {

        loginRepository.save(new LoginVO(loginVo.getUsername(), loginVo.getPassword(), loginVo.getEmail(),"Y"));
    }

}

响应类别

    package com.angularjs.app.message;

public class Response {

    private String status;
    private Object data;

    public Response() {

    }

    public Response(String status, Object data) {
        this.status = status;
        this.data = data;
    }

    public String getStatus() {
        return status;
    }

    public void setStatus(String status) {
        this.status = status;
    }

    public Object getData() {
        return data;
    }

    public void setData(Object data) {
        this.data = data;
    }
}

模型类

    package com.angularjs.app.model;
import java.io.Serializable;

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

@Entity
@Table(name = "user_details")
public class LoginVO implements  Serializable{

    private static final long serialVersionUID = -3009157732242241606L;
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column (name="user_id")
    private long userId;

    @Column (name="user_name")
    private String username;

    @Column (name="valid_user")
    private String validUser;

    @Column (name="password")
    private String password;

    @Column (name="email")
    private String email;

    public LoginVO(String username, String password, String email, String validuser) {
        this.username = username;
        this.password = password;
        this.email = email;
        this.validUser = validuser;
    }

    public long getUserId() {
        return userId;
    }

    public void setUserId(long userId) {
        this.userId = userId;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getValidUser() {
        return validUser;
    }

    public void setValidUser(String validUser) {
        this.validUser = validUser;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    @Override
    public String toString() {
        return String.format("Customer[userId=%d, username='%s', email='%s']", userId, username, email);
    }

}

回购类

   package com.angularjs.app.repo;

import org.springframework.data.repository.CrudRepository;
import org.springframework.stereotype.Service;

import com.angularjs.app.model.LoginVO;
@Service
public interface LoginRepository extends CrudRepository<LoginVO, Long> {

    LoginVO findByUsername(String userName);
}

通过在Application类上添加@EntityScan(basePackageClasses=LoginVO.class)，我的问题已解决。
