JPA一對多制作可以選擇查詢

Question

使用@ManyToMany時，JPA有很多選擇查詢

關系是

Person 1 : Bank N, Bank 1 : Account N

這是我的代碼：

@Entity
public class Person {

    @Id
    @Column(unique = true, nullable = false)
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;

    private String name;

    @OneToMany(cascade = CascadeType.ALL)
    @JoinColumn(name = "person_id")
    private List<Bank> banks;
}

@Entity
public class Bank {

    @Id
    @Column(unique = true, nullable = false)
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;

    private String name;

    @OneToMany(cascade = CascadeType.ALL)
    @JoinColumn(name = "bank_id")
    private List<Account> accounts;
}

@Entity
public class Account {

    @Id
    @Column(unique = true, nullable = false)
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;

    private String name;
}

和查詢日志是：

select ....
select ....
select ....
select ....
select ....
...

如果包含關系的表上的行數增加，則查詢數將增加。

並且性能更低...我想解決這個不斷增長的查詢問題。

如何在JAP或更少的查詢上創建一個選擇查詢？
