mybatis3+spring3MVC
mybatis3+spring3MVC
最近,正在为公司搭建java部门的开发平台,记录下搭建的整个过程。
1. 环境介绍
1.1. JDK
jdk1.6.0_04
1.2. Web服务器
Tomcat6.0.29-windows-x86
1.3. 开发工具
Eclipse3.7 (Version: Indigo Release Build id: 20110615-0604)
1.4. 使用的框架
后端:Mybatis(3.0.5) + Spring(3.0.5)MVC
前端:jQuery1.5.1
1.5. 数据库
MySQL(5.1)
2. 搭建过程
2.1. 项目结构
整个工程的编码是“utf-8”(包括里面所有的文件)。首先看一下整个项目的结构(里面涉及到公司名称的部分进行了处理):
接着,看看需要哪些jar包:
2.2. 配置文件

其中,需要注意的2个地方是:
1. jdbc.properties文件的位置:
- <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
- <property name="locations">
- <list>
- <value>classpath:jdbc.properties</value>
- </list>
- </property>
- </bean>
这里指的是classpath的位置,如果还有文件夹,可以写成“XXX / jdbc.properties”
2. mybatis-config.xml文件的位置:
- <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
- <property name="dataSource" ref="dataSource"></property>
- <property name="configLocation" value="classpath:mybatis-config.xml"/>
- </bean>
与jdbc需要注意的是一样的。
