说明：

1.用到了Struts2和hibernate没有用到spring综合去管理项目

2.tomcat中的端口为8080没有修改过的，你那边也默认为8080，然后不用改了，部署好了之后直接浏览器中输入http://localhost:8080/Struts2Demo/login 

3.所有的要自己新建的配置文件（比如:struts.xml，hibernate.cfg.xml，log4j.properties）都只需要在选中src文件夹，然后新建相应的文件就行了

4.关于log4j--其实这个你想要的效果可以去配置这个log4j.properties文件（就是日志的格式，或者日志存储的目的地等），我随便配的，效果应该不是你想要的

5.没有分页，注销没有写（注销的话把session删了，然后跳回登录页面就行了）

6.前台没有css，前段框架之类的，如果你会前段框架可以把一些按钮，表单之类的美化下（可以用bootstraps，这个只要引入js,css文件就可以用了）

7.还有就是回复应该是写了，但是没有测试（就是说方法有了，还没测试）

数据库

  数据库只有3个 表，分别是users,posters,contents

users--用户表

posters--帖子表，所有的帖子都放在这个里面

contents--评论表（但对评论的回复也放在这个表中，查的时间只要关联查出来就行，但我觉得这个设计有问题，不过有没有好的方案，所以有点纠结，你自己看下。。或者重新设计个表。。。。）

新建数据库和表

新建数据库

安装mysql后新建一个数据库 stu，格式如下：

新建完数据库后就可以在库中新建表了，具体执行下面的语句。(语句中包含一些测试数据，你可以进去看到效果)
