db.properties 用于通过属性文件连接数据库。如果在SqlMapConfig.xml中直接连接数据库则不需要这个。
driver=com.mysql.jdbc.Driver url=jdbc:mysql://192.168.1.74:3306/test user=root password=root
SqlMapConfig.xml 连接是的mysql数据库。需要加入mysq jar包mysql-connector-java-5.1.15-bin.jar 和ibatis核心包ibatis-2.3.4.726.jar

怎么样，ibatis也不是很难吧，将所有的SQL语句统一管理起来，十分方便，对于写复杂的SQL语句也可以直接来写
顺便介绍下MyBatis
MyBatis来源于iBATIS，iBATIS是一个由Clinton Begin在2001年发起的开放源代码项目，iBATIS一词来源于“internet”和“abatis”的组合。该项目最初侧重于密码软件的开发，现在是一个基于Java的持久层框架。iBATIS提供的持久层框架包括SQL Maps和Data Access Objects（DAO），它是著名的ORM开发框架，分为Java和.NET版本，有着众多的追随者。
iBATIS更名为MyBatis并迁移到Google Code，此次项目迁移后，将启用新的网站http://www.mybatis.org/，由于目前只是改了名字，因此仍然可直接浏览iBatis的文档。
MyBatis开发团队希望脱离Apache而独立发展，并保证不会修改授权协议（Apache License）、代码完全兼容、包名不会更改、也不会删除 Apache站上的任何相关资源。
改名后的第一次版本MyBatis 3.0.1已经发布，基于iBatis 3.0版本，该版本非常稳定，已经有很多用户使用了数周时间，修复了一些小bug。欲下载 MyBatis 3.0.1请到它新的网站http://www.mybatis.org/。
