org.hibernate.id.IdentifierGenerationException: ids for this class must be manually assigned before calling save(): ***(POJO类，及持久化类名)

分析及解决：

你要操作的数据表中的id（即主键）的类型设置成了“自动增长类型”，而在你的

hibernate.cfg.xml中，id的生成方式是assigned，即
<id name="id" type="integer">
            <column name="id" />
            <generator class="assigned" />
</id>
这种搭配是矛盾的！

主键的assigned生成方式由程序自动生成表的主键，即在你的测试程序中要调用setId()方法，且必

须在调用save()前调用（或者说在调用save()前必须指定id，其实就是说，主键值不能为空！）。
把主键的生成方式改为native，它的特征是能够根据底层数据库自动选择主键生成方式。
