原因可能是什么 您正在DAO中打开一个新会话，该会话未链接到当前的Spring事务。不要那样做。而是获取链接到当前事务的当前会话：
Session session = sessionfactory.getCurrentSession();

如果您尝试在不使用hibernate的情况下运行类似的insert，它是否有效？您是否尊重所有非空、外键等约束？正常插入正在工作，所有字段都已提交，正常表除主键外没有约束！可以通过向主键添加值来测试hibernate命令吗？我不喜欢hibernate，我只是给出一些一般的想法。主键不是（自动），所以我必须在表单中手动输入。id已提交！还是不行！不确定它是否相关，但hibernate属性中有一个输入错误：您编写了
