spring启动applicationcontext时出错/创建名为“entitymanagerfactory”的bean时出错

原谅我缺乏知识，我是新来的春靴，我就是搞不懂这个。我的编辑是intellij idea。
慰问

我觉得这个很简单，因为我刚开始这个项目。我查过类似的问题，但解决方案似乎不起作用。
应用程序.yml

用户.java

package com.skelo.projekat.entities;

import javax.persistence.*;

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

    @Id
    @Column
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Integer id;

    @Column(name = "name", nullable = false)
    private String name;

    // GETTERS AND SETTERS

    public Integer getId() {
        return id;
    }

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

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

用户存储库.java

package com.skelo.projekat.repositories;

import com.skelo.projekat.entities.User;
import org.springframework.data.jpa.repository.JpaRepository;

public interface UserRepository extends JpaRepository<User, Integer> {

}

其余的文件是不变的，所有包都在项目中。
我尝试过添加hibernate依赖项，但没有效果。
