需要的依赖介绍：
spring-webmvc 导入该jar包会自动导入很多spring相关依赖的包
jackson-core,data-bind,annotations 这三个是json相关的包
spring-jdbc,mybatis,mybatis-spring两者结合的一个插件,mysql-connector-java 是mysql驱动,commons-dbcp数据库连接池
junit测试

配置spring-mybatis.xml 包含bean: dpcp链接池, mybatis的session工厂, mybatis自动扫描接口
dpcp连接池：
id=dataSource 其参数是包下的set方法取消set，并且把第一个字母换成小写
driverClassName/url/username/password
session工厂：来自mybatis-spring这个包
sqlSessionFactoryBean dataSource ref='引用前面定义好的的dataSource对象'
mapperLocations 生命mybatis sql声明文件保存的地方 value="classpath:mapper/*.xml"
mybatis自动扫描接口： 数据访问接口的存放位置
mybatis-spring包下 org.mybatis.spring.mapper包下的 MapperScannerConfigurer方法 basePackage
