1.首先以一個(gè)項(xiàng)目做例子，該項(xiàng)目用到的框架即為SpringMVC+mybatis,項(xiàng)目環(huán)境為MyEclipse+sqlserver+tomcat6，項(xiàng)目的地址（項(xiàng)目+數(shù)據(jù)庫備份文件）大家可以上我的百度云下載http://pan.baidu.com/s/1o8qDqxs

2.還原項(xiàng)目怎么還原這里不具體說了，打開項(xiàng)目，找到ApplicationContext.xml,先改變一下數(shù)據(jù)庫的連接，把用戶名和密碼設(shè)成自己的數(shù)據(jù)庫的用戶名和密碼

3.我們現(xiàn)在整體看一下這個(gè)項(xiàng)目的結(jié)構(gòu)，首先是整合SpringMVC,Appicationcontext-mvc.xml

4.整合mybitas,ApplicationContext.xml

5web.xml整合SpringMVC和mybitas

6.當(dāng)我們新增一個(gè)對(duì)象的時(shí)候，先要在Applicationcontext.service中注入該對(duì)象的service，然后再在mybatis文件夾中增加該對(duì)象對(duì)應(yīng)的xml文件
