之前在csdn发布了mybatis的入门学习帖---http://bbs.youkuaiyun.com/topics/390605626
开发工具:eclipse 所需jar包 mysql-connector-java-5.1.7-bin.jar(mysql连接jar包) mybatis-3.2.3-SNAPSHOT.jar(mybatis核心jar包)mybatis-spring-1.1.1.jar(和Spring整合必须的) 其他jar包(主要是Springweb框架jar包 官网有下载)
同样以一个实体类为例讲述---
简单用个实体类吧--
这是基于注解spring配置
ITschool-servlet.xml 这个文件名字定义 内容如下:-->

最关键的一步了 就是调用了(实现数据的插入)客户端代码
context=new ClassPathXmlApplicationContext("SpringIt.xml");(这个SpringIt.xml在src根路径下,内容就是上面的配置)
StudentDao studao=(StudentDao)context.getBean("StudentDao");
//实现数据的插入。。。。
Student stu=new Student();
stu.setSno("123");
stu.setSname("张三");
stu.setSex("男");
studao.addStudentInfos(stu);
//OK执行完成!数据插入到数据库、
