Spring boot: Ошибка создания компонента с именем 'jpaMappingContext': сбой вызова метода init;

Question

Я использую простое приложение для весенней загрузки, которое должно подключаться к базе данных PostgreSQL и обеспечивать функциональность сервера, отправляя и получая запросы и ответы JSON.Это проект maven.

Это мои зависимости pom.xml

    <dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>

</dependencies>

Это единственный контроллер, который я сейчас использую.

        package com.server.controller;

    import com.server.entity.User;
    import com.server.service.UserService;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.http.HttpStatus;
    import org.springframework.http.ResponseEntity;
    import org.springframework.web.bind.annotation.*;

    import java.util.List;

    @RestController
    public class UserController {

        @Autowired
        UserService userService;
        @RequestMapping(value = "/users/{id}", method = RequestMethod.GET)
        public ResponseEntity<User> getUserById(@PathVariable Long id) {
            return new ResponseEntity<User>(userService.findById(id),HttpStatus.OK);
        }

        @Autowired
  @RequestMapping(value = "/users", method = RequestMethod.GET)
    public ResponseEntity<List<User>> getUsers() {
        return new ResponseEntity<List<User>>(userService.getAll(),HttpStatus.OK);
    }

    @Autowired
    @RequestMapping(value = "/users", method = RequestMethod.POST)
    public ResponseEntity<String> createAccount(@RequestBody User user) {
        userService.create(user);
        return new ResponseEntity<String>("Successful!", HttpStatus.CREATED);
    }
}

Этоэто реализация User

    package com.server.entity;

import javax.persistence.*;

@Entity
@Table(name = "login")
public class User {

    @Id
    @Column(name = "userID")
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    long id;

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

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

    public User() {
        super();
    }

    /**
     * User constructor.
     * @param username Receives a username String.
     * @param password Receives a password String.
     */
    public User(String username, String password) {
        super();
        this.username = username;
        this.password = password;
    }

    public String getUsername() {
        return username;
    }

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

    public String getPassword() {
        return password;
    }

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

    public long getId() {
        return id;
    }

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

}

Это основной класс сервера

    package com.server;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.data.jpa.JpaRepositoriesAutoConfiguration;
import org.springframework.boot.autoconfigure.domain.EntityScan;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.boot.autoconfigure.jdbc.DataSourceTransactionManagerAutoConfiguration;
import org.springframework.boot.autoconfigure.jms.JndiConnectionFactoryAutoConfiguration;
import org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;

@EnableAutoConfiguration(exclude = {JndiConnectionFactoryAutoConfiguration.class,DataSourceAutoConfiguration.class,
        HibernateJpaAutoConfiguration.class, JpaRepositoriesAutoConfiguration.class, DataSourceTransactionManagerAutoConfiguration.class})
@SpringBootApplication
@ComponentScan("com.server.service.UserService")
@EnableJpaRepositories("com.server.repository.UserRepository")
class Main {

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

}

Я рассмотрел все другие вопросы, связанные с этим исключением, которые я мог найти, и ни одиниз них, кажется, работают.Я пытался удалить и добавить определенные зависимости и изменить строку exclude внутри @EnableAutoConfiguration.

Я очень новичок в весенней загрузке.так что пропустить что-то очевидное не исключено.Помощь очень ценится
