Struts2+Spring3+Mybatis3开发环境搭建

本文主要介绍Struts2+Spring3+Mybatis3开发环境搭建

Struts和Spring不过多介绍。

MyBatis 是支持普通 SQL 查询,存储过程和高级映射的优秀持久层框架。MyBatis 消除了几乎所有的 JDBC 代码和参数的手工设置以及结果集的检索。MyBatis 使用简单的 XML 或注解用于配置和原始映射,将接口和 Java 的 POJOs(Plan Old Java Objects,普通的 Java 对象)映射成数据库中的记录。

环境：

Struts-2.3.14

Spring-3.2.1

MyBatis-3.2.2

在apache-tomcat-7.0.39下测试通过
