JPQL 조인 강의를 따라하고 있는데 이런 에러가 납니다.

'Basic' attribute type should not be 'Persistence Entity'

package jpql;

import javax.persistence.*;
@Entity
@Table(name = "MEMBER")
public class Member {

    @Id @GeneratedValue
    private Long id;
    private String username;
    private int age;

    @ManyToOne
    @JoinColumn(name = "TEAM_ID")
    private Team team;

    public void changeTeam(Team team){
        this.team = team;
        team.getMembers().add(this);
    }

    public Team getTeam() {
        return team;
    }

    public void setTeam(Team team) {
        this.team = team;
    }

    public Long getId() {
        return id;
    }

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

    public String getUsername() {
        return username;
    }

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

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    @Override
    public String toString() {
        return "Member{" +
                "id=" + id +
                ", username='" + username + '\'' +
                ", age=" + age +
                ", age=" + age +
                '}';
    }
}

어떻게 해결하면 좋을지 알 수 있을까요?
