JavaWeb_(SpringMVC框架)SpringMVC&Spring&MyBatis整合
JavaWeb_(SpringMVC框架)测试SpringMVC&Spring&MyBatis三大整合 传送门
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
b)配置 -> web.xml
i.读取spring配置文件;
ii.配置springmvc前端控制器;
