人力资源管理系统开发----框架整合

整合思路

我这次开发的是人力资源管理系统，采用的是mybatis+spring+springMVC架构，其中mybatis和spring是两个不同的框架，而spring和springmvc是同一个框架，他们可以无缝对接，因此不需要额外的整合。

整合的大概步骤

整合的时候分层整合
dao层：
采用mybatis框架，需要和spring整合。
1. 创建SqlMapConfig.xml ———这个文件是框架要求要的。
2. 创建applicationContext-dao.xml ——这个文件是mybatis和spring整合的文件，就是将mybatis交付给spring来管理，这个文件要做的是1.配置数据源，2.让spring容器管理sqlsessionFactory（单例），3.把mapper代理对象放到spring容器中（使用包扫描的方式）
service层：
1. 配置事务管理，创建applicationContext-trans.xml
2. 将实现类放到spring中,创建applicationContext-service.xml,主要是使用包扫描，将service层的实现类放入到spring容器中。
表现层：
1. 创建springmvc.xml,(扫描包，配置注解驱动和配置视图解析器）
2. web.xml（加载spring容器，解决post乱码配置springmvc的前端控制器）
