Spring EntityManagerFactory未能初始化

伙计们 我有这个实体：

import lombok.*;

import javax.persistence.*;
import java.util.List;



@Entity
@Table(name = "clients")
@Getter
@Setter
@NoArgsConstructor
@AllArgsConstructor
public class Client {

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

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

    @Column(name = "first_name")
    private String firstName;

    @Column(name = "last_name")
    private String lastName;

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

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

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

    @ManyToOne(fetch = FetchType.EAGER, optional = false)
    @JoinColumn(name = "role_id")
    private Role role;

    @OneToMany(mappedBy = "client", fetch = FetchType.EAGER, cascade = CascadeType.ALL)

    @OneToMany(mappedBy = "client", fetch = FetchType.EAGER, cascade = CascadeType.ALL)

}
