JavaWeb_(SpringMVC框架)SpringMVC&Spring&MyBatis整合
JavaWeb_(SpringMVC框架)测试SpringMVC&Spring&MyBatis三大整合
1、整合ssm 3大框架 过程
a)导包 -> spring_Jar整理 -> ssm框架整合包
b)配置 -> web.xml
i.读取spring配置文件；
ii.配置springmvc前端控制器；
c)配置 -> applicationContext.xml
i.读取数据库配置文件；
ii.配置数据源连接池；
iii.开启注解扫描；
iv.配置事务核心管理器；
v.开启注解事务；
vi.配置视图解析器；
vii.配置Mybatis：
1.配置sqlSessionFactory；
2.配置别名；
3.配置mapper工厂；
a)导包 -> spring_Jar整理 -> ssm框架整合包
