java留言回复功能代码 java留言回复功能代码是什么

IT技术留言

用Java做一个类似于QQ空间留言板的功能 。。。不用数据库也能实现. 及时性的罢了；
要是数据库的话：方法一（用于有条件性的，比如只显示对方发的信息）
1user表id , use两列
2messages表id , message , message_person , use_id (外键)四列
方法二（双方都用select * form messages查询所有信息）
1messages表id , message两列
急急急！java简单留言板您好 。我重新地帮你写了代码，完全地符合了你的图片中的界面要求、功能要求 。代码如下：（解决了问题 ， 记得给我分哦~^_^呵呵……）
