工具：myeclipse ，数据库：Oracle ，jar包：classes12.jar
实现的功能：对客户的增删改查，展示客户列表，一页显示十条客户数据，实现分条件查询（根据ID，名称等）
这个小Demo用到了：
1，使用jsp+servlet，工厂模式，代理类
2，后端分页技术
3，ajax前后台交互
代码如下：
/**
*客户接口类
*/
public interface CustomerDAO {
/**
* @param pojo 客户类
* @return 新增客户
*/
public boolean doIns(CustomerPOJO pojo);
/**
* @param customerId 客户id
* @return 删除客户
*/
public boolean doDel(BigDecimal customerId);
/**
* @param pojo 客户类
* @return 更新客户信息
*/
public boolean doUpd(CustomerPOJO pojo);
/**
* @param customerId
* @return 根据客户id，名称查询客户所有信息
*/
public CustomerPOJO findById(BigDecimal cid);
/**
* @param customerName
* @return 根据客户名查询全部信息
*/
public CustomerPOJO findByName(String cname);
/**
* 列出所有客户
*/
public List<CustomerPOJO> findAll(int pageSize, int pageCurrent);
/**
*查询客户数量
*/
public int findAllCount();
}
