这个异常的原因我出现过！解决途径：
第一步：看配置文件的主键生成策略！看看是不是自增长（native等），不同的数据库不一样！注意

第二步：看看数据库是不是设置了自增长，而且要确保你已经给自增长设置了增长值！比如自增长1！！



主键生成策略是指 <grnerator class="native"/>

1、 native
       对于 oracle 采用 Sequence 方式，对于MySQL 和 SQL Server 采用identity（自增主键生成机制），native就是将主键的生成工作交由数据库完成，hibernate不管（很常用）

2、assigned
      在插入数据的时候主键由用户自己添加，hibernate也不管（很常用）

3、increment
      插入数据的时候hibernate会给主键添加一个自增的主键，但是一个hibernate实例就维护一个计数器，所以在多个实例运行的时候不能使用这个方法

4、sequence
      调用数据库的sequence来生成主键，要设定序列名，不然hibernate无法找到：
      <param   name="sequence">NAME_SEQ</param>（Oracle中很常用）

5、identity
      使用SQL Server 和 MySQL 的自增字段，这个方法不能放到 Oracle 中，Oracle 不支持自增字段，要设定sequence（MySQL 和 SQL Server 中很常用）

6、hilo
      使用hilo生成策略，要在数据库中建立一张额外的表，默认表名为hibernate_unique_key,默认字段为integer类型，名称是next_hi（比较少用）
      我们也可以自己设置自定义的表名和字段名
<id name="id" type="integer">
   <column name="id"/>
   <generator class="hilo">
      <param name="my_unique_key"/>
      <param column="next_hi"/>
   </generator>
</id>

7、sehilo
      通过hilo算法实现，但是主键历史保存在Sequence中，适用于支持 Sequence 的数据库，如 Oracle（比较少用）

8、uuid.hex
       hibernate会算出一个128位的唯一值插入

9、uuid.string
       hibernate会算出一个16位的值插入

10、foreign
        使用外部表的字段作为主键

11、select
        使用触发器生成主键（主要用于早期的数据库主键生成机制，少用）
