我有两个具有简单@OneToMany关系的对象，其外观如下：

父母：

@Entity
public class ParentAccount {

  @Id
  @GeneratedValue
  private long id;
  private String name;

  @OneToMany(fetch = FetchType.EAGER, mappedBy = "parentAccount")
  private Set<LinkedAccount> linkedAccounts;

}

儿童：

@Entity
public class LinkedAccount {

  @Id
  @GeneratedValue
  private long id;

  @ManyToOne(optional = false)
  private ParentAccount parentAccount;

  private String name;

  // empty constructor for JPA
  public LinkedAccount() {
  }

}

我可能使用Spring CrudRepository来处理这些实体。但是，在调用时ParentAccount parent = parentAccountRepository.findOne(id);，会开始发生某种无限循环，并在整个控制台中将其变为垃圾邮件hibernate状态：

Hibernate: select linkedacco0_.parent_account_id as parent_a6_1_0_, linkedacco0_.id as id1_0_0_, linkedacco0_.id as id1_0_1_, linkedacco0_.aws_id as aws_id2_0_1_, linkedacco0_.key_id as key_id3_0_1_, linkedacco0_.name as name4_0_1_, linkedacco0_.parent_account_id as parent_a6_0_1_, linkedacco0_.secret_key as secret_k5_0_1_ from linked_account linkedacco0_ where linkedacco0_.parent_account_id=?

我尝试将获取类型更改为LAZY，但随后出现此错误：

org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: com.berrycloud.scheduler.model.ParentAccount.linkedAccounts, could not initialize proxy - no Session

（似乎它正在尝试在事务上下文之外进行延迟加载）。

这是我的CRUD存储库：

@Repository
public interface ParentAccountRepository extends CrudRepository<ParentAccount, Long> {
}

有人可以告诉我如何解决这个问题吗？我更喜欢使用EAGER fetch的解决方案。谢谢你的提示

编辑：这是我正在使用的架构

CREATE TABLE parent_account (
    id BIGINT auto_increment,
    name VARCHAR(80) null,
    PRIMARY KEY (`id`)
);

CREATE TABLE linked_account (
    id BIGINT auto_increment,
    parent_account_id BIGINT,
    name VARCHAR(80) null,
    FOREIGN KEY (`parent_account_id`) REFERENCES `parent_account` (`id`),
    PRIMARY KEY (`id`)
);
