设置了自增长的。debug了2天，后来才发现是dubbo service 调用的原因。然后在service层调用dao层时保存数据后，再对象.getId() 将主键返回就行了，居然它不自动装载到对象里。例如Service层的代码：public Integer insertSelective(T entity){return dao.insertXz(entity);} 修改为public Integer insertSelective(T entity){dao.insertXz(entity);return entity.getId();} 这样就行了。将之前的返回的受影响的行数变为主键ID即可，不知道为什么在Service层entity不自动装载，我猜测也许就是Dubbo的原因。。哈哈，反正问题是解决了，谢谢楼主回答
