Hibernate代码生成外键引用对象

我正在使用Hibernate反向工程。。。 我有一个表用户。 我有带有Recipe_FK-to User.userId的表Recipe

运行代码生成时，我会为用户获得一个POJO文件，其中包含：

private Set<?> recipeses = new HashSet<Object>(0);

private Set recipes=new HashSet（0）；

现在-几个问题： 1.当我执行session.load（User.class，userId）时； 它真的会加入吗？然后从配方表中获取配方？我不想。。。。 我可以手动删除它吗？ 如何在不获取此“设置”参考参数的情况下反转表格

（当需要提高性能时，我更喜欢手动执行连接。）

以下是.hbm.xml文件：

见这一行：

<set name="recipeses" table="recipes" inverse="true" lazy="true" fetch="select">

这是必须知道的。在使用Hibernate之前请阅读，否则您的应用程序将是一场灾难。你必须了解它是如何工作的，以避免犯错误

我强烈建议您在映射中使用注释，而不是XML。它更标准，不太冗长，更容易理解。
