Java web ssh框架实现点击数这个功能
这个点击数要存到数据库，然后从数据库中拿?还是直接可以在jsp页面可以直接得到。
我用的是el表达式 展开
一个简单的用户登录。创建好一个web工程后，添加为Spring工程添加hibernate工程是会将hibernate.cfg.xml集成到applicationContext中既然是用户登录首先需要一个实体类。

- 与数据库建立关系映射User.hbm.xml
<hibernate-mapping>
<class name="com.entity.User" table="user" catalog="demo">
<id name="id" type="java.lang.Integer">
<column name="id" />
<generator class="identity" />
</id>
<property name="username" type="java.lang.String">
<column name="username" length="20" />
</property>
<property name="password" type="java.lang.String">
<column name="password" length="20" />
</property>
</class>
</hibernate-mapping>
