接着上一篇博客写，记：数据库课程设计（一）;

首先又对上一次的数据库结构和字段类型进行了微调：

下面介绍一下真个开发框架和我设想的基本步骤：

开发框架：利用javaEE（javaEE5）进行开发，使用Spring 框架和 Hibernate持久层框架（其中可能还是会写一些sql语句，毕竟是数据库课设嘛）

数据库选择：SQL Sever 2005

开发工具（软件）：SybasePowerDesigner，SQL Server Management Studio 2008，MyEclipse 9

所用知识：Java基础，JavaEE知识，hibernate知识，数据库知识，javascript，jquery，css3，html5（前端开发打算尝试使用html5）

步骤：

1.数据库设计（已完成）

2.建立java web工程，利用hibernate反向工程生成相应的model，导入需要的lib，设计最初的包结构（model，controller，imp）和目录结构（page，css，js，imagine）

3.初步设计完成课设要求的html功能页面

4.编写jsp和后台java代码（sql语句）

5.修改调试

（6.找老师检查）

刚刚完成功了第二步，详细信息如下：

<1>.工程结构（如图）：

<2>.利用powerdesigner生成sql文件：

<3>.利用SQL Server Management Studio执行sql文件：

<4>.利用Myeclipse hibernate反向工程生成相应model：

首先进入Myeclipse Database Explorer，

建立相应的数据库连接：

生成相应model：

<5>.Spring和数据源的相关配置：

（跟mysql，oracle的区别只是把hibernate的sql方言改一下就好了）

把生成的model的相关信息注册到sessionFactory

applicationContext.xml内容如下：

datasource-conf.properties内容如下：

driverClass=com.mysql.jdbc.Driver
jdbcUrl=jdbc\:sqlserver\://localhost\:1433;databaseName\=zys_test

testConnectionOnCheckout=false

hibernate.dialect=org.hibernate.dialect.SQLServerDialect

hibernate.show_sql=true//true只是为了调试起来方便

以后我还会更新博客记录我的课设过程，最后完成之后会上传全部的源代码和大家交流。

好了，今天就写到这里，刚吃完了饭，小睡一会儿~~
