基于JDBC Driver 4，tomcat7.0，sql server 2005。内容包含对数据库的添加、删除、编辑、查询最基本的操作，代码尽量简短未考虑安全等因素。
Step 1：安装SQL server 2005，并配置其属性。
1、启动sqlserver服务（配置工具-sql server configuration manager-sql server2005服务-右键sqlexpress-启动）
2、启用TCP/IP协议（配置工具-sql server configuration manager-网络配置-SQLEXPRESS的协议-TCPIP-已启用）
3、配置端口（配置工具-sql server configuration manager-网络配置-SQLEXPRESS的协议-TCPIP属性-IPALL的动态端口，默认为1433）
4、设置混合验证（sql server management studio-服务器属性-安全性-混合验证）
5、sa授权登陆（sql server management studio-安全性-登录名-sa属性-状态-登陆-启用）
6、sa密码设置（sql server management studio-安全性-登录名-sa属性-常规[强制密码策略不勾选]）
7、重新启动sqlserver服务（配置工具-sql server configuration manager-sql server2005服务-右键sqlexpress-重新启动）
8、测试（sql server management studio:服务器名称localhost，sql server用户登录，使用sa用户。）若成功，证明可以通过tcpip协议1433端口sa超级管理员登录。
若发现数据库中的中文都变成了问号，则可以参看http://zhiyongliu.iteye.com/blog/1846449
Step 2：下载JDBC驱动，并解压缩。(附件中也有.)，jdk自己安装吧。

官方下载地址：http://www.microsoft.com/en-us/download/details.aspx?displaylang=en&id=11774
将驱动jdbc.jar或者jdbc4.jar 拷贝到：站点根目录/WEB-INF/lib 中，注意JDBC驱动的版本以及对JDK版本的要求。
Step 3：新建数据库database，运行下面的sql脚本创建表dataTableName（id, title, content）
SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO IF NOT EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[dataTableName]') AND type in (N'U')) BEGIN CREATE TABLE [dbo].[dataTableName]( [id] [int] IDENTITY(1,1) NOT NULL, [title] [nvarchar](max) NULL, [content] [nvarchar](max) NULL, CONSTRAINT [PK_dataTableName] PRIMARY KEY CLUSTERED ( [id] ASC )WITH (IGNORE_DUP_KEY = OFF) ON [PRIMARY] ) ON [PRIMARY] END
step4:以下文档为基本操作
