你需要显示代码。 – Subin

我已经添加了模型类，在那里我得到异常 – user1904829

懒惰初始化，当你有beetween对象的关系，例如发生异常时，（一到多）客户端有很多汽车。 所以会发生的是，你做了一个查询，得到一个客户列表，然后你关闭会话。在此之后，如果您尝试访问客户端对象内的汽车集合（未加载），您将得到异常。你没有发布你的代码......这将有助于更多。

编辑： 和多数民众赞成正是你的异常告诉

未能懒洋洋地初始化角色的集合： com.mypersonal.model.User.broadband，没有会话或会话关闭

您需要在用户中热切加载属性“宽带”。应该很容易解决。 Hibernate在默认情况下会延迟加载集合，你只需要在注释中添加fetch = FetchType.EAGER或者在xml中做类似的事情。

另一个选择是调用宽带属性，但它尚未从会话中分离出来。为此，您需要知道您的交易在哪里结束，您的会话已关闭，以便之前完成交易。然后Hibernate会填充该字段而不会抛出错误，因为它仍然可以访问数据库。

了解Hibernate是出于性能原因做这些事的。如果您在一个查询中获取所有内容，则最终可能会获取整个数据库（披萨效应）。

您应该做出预先抓取

public Set<UserBroadband> getBroadband()@OneToMany(fetch = FetchType.EAGER

或会话关闭之前做你的JSON序列化。

在会话关闭后序列化实体对象时，它无法在该对象中获取延迟集合。

我试过FetchType.Eager，然后我的jvm内存不足。 你可以解释我第二个选项，我没有尝试过相同的 – user1904829

这意味着你的设置真的很大，你应该重新考虑序列化它，因为你在评论中考虑@JsonIgnor它 – Subin

有多个字段延迟初始化，除非您在会话中序列化，或更改其获取类型，否则这将失败。 – Robin

需要问的第一个问题是他们是否需要收藏。如果他们需要集合，那么最好将其设置为EAGER加载。

如果在序列化过程发生之前不需要集合，请将所有集合设置为null。

通过将所有集合设置为null，我得到了我的工作。
