Spring与SpringMVC整合

Spring与SpringMVC整合

Spring容器是Springmvc容器的父容器。因此在Springmvc容器中是可以访问到Spring容器中的bean,而在Spring中是无法访问到Springmvc所定义的bean。在Web开发中，Controller层一般都用Springmvc来扫描，其余全在Spring容器中。

最佳实践：

​ Controller在Springmvc中扫描，视图解析器等在Springmvc中配置。

​ Spring中扫描Service和Dao层以及其他组件，事务定义，数据源定义都在Spring中配置。

Springmvc中的配置

web.xml中配置
