  用户注册或者信息的id应该怎么设置成自动生成的？？？


------解决方案--------------------
你没传id，数据库里又没有设置默认值，是这个意思吧
------解决方案--------------------
你ID没有设置自增长吗.或者建个序列.
------解决方案--------------------
id int not null auto_increment primary key
------解决方案--------------------
那要看你用的什么,是servlet?还是struts框架?如果是框架的话,表单里,标签的name属性要和你对象.属性名如:name = "user.username";还有就是action一定要给get和set方法
如果你是用的servlet的话,取request.getParameter("username");
这里最好你在控制台输出一下,看是否有取到值.
