1 个答案:

答案 0 :(得分：0)

您的某个CurrencyExchange或用户已暂停初始化attribut。

第一个选项应该是获取延迟的初始化数据，但您可能不需要这些数据。

另一个选择是创建数据传输对象类：

public class UserDto {

  private Long id;

  // other attributs


  public UserDto(Long id, ...) {
    this.id = id;
    // ...
  }

}

然后您可以使用新方法检索用户：

findUserDto(Long id) {

  Query query = em.createQuery("select new UserDto(user.id, ...) from UserDto user where user.id = :userId");
  query.setParameter("userId",id);
  return query.getResultList();
}
