mybatis3+springmvc4+spring4整合教程

一、包的准备

springmvc4

spring4

mybatis

c3p0

mybatis-spring-1.3.0(版本要1.3以上)

commons-logging（公共日志包）

mysql-connector-java（mysql连接驱动包）

二、包的导入

导入包的目录：

spring4+springmvc4：

spring-framework-4.3.1.RELEASE\libs目录下有很多包，但不需要每个都导入，这里只需要导入以下包：

spring-aop-4.3.1.RELEASE.jar

spring-beans-4.3.1.RELEASE.jar

spring-context-4.3.1.RELEASE.jar

spring-context-support-4.3.1.RELEASE.jar

spring-core-4.3.1.RELEASE.jar

spring-jdbc-4.3.1.RELEASE.jar

spring-orm-4.3.1.RELEASE.jar

spring-tx-4.3.1.RELEASE.jar

spring-web-4.3.1.RELEASE.jar

spring-expression-4.3.1.RELEASE.jar

spring-webmvc-4.3.1.RELEASE.jar

c3p0：

将以下两个包导入

c3p0-0.9.2.1.jar

mchange-commons-java-0.2.3.4.jar

commons-logging、mysql-connector-java、mybatis-spring-1.3.0(版本要1.3以上)：

找到包全部导入即可

三、文件配置
