springMvc-09 SSM框架整合
框架整合的方便之处
1）单独使用myBatis的时候，要操作数据库，每次都需要通过SqlSessionFactory和SqlSession方式获取Mapper对象
2）在Spring和Mytis整合之后，无需再通过SqlSessionFactory和SqlSession方式获取Mapper对象，所有Mapper和Dao对象都交给了Spring框架管理，获取Bean的时候，通过ApplicationContext对象获取即可。
3）SSM框架整合是把三大框架整合在一起使用，Web.xml导入Spring配置和SpringMvc配置，在Web容器启动的时候，启动Spring框架容器，从Model，Dao，Service，Controller都采用注解方式，就可以实现直接在Controller里边使用Service的注入对象，无需再使用ApplicationContext获取Bean对象。
