ssm框架的集成

整合三大框架的思路:
Dao层:整合mybatis和Spring需要的JAR包:
1、mybatis的JAR包 2、Mysql数据库驱动包 3、数据库连接池
4、mybatis和Spring的整合包 5、Spring的JAR包
配置文件:
1、mybatis的配置文件:SqlMapConfig.xml 2、Spring的配置文件:applicationContext-dao.xml
a.数据源 b.连接池 c.配置sqlSessionFactory(mybatis和Spring整合包中的) d.配置mapper文件的扫描器
Service层:使用的jar包:Spring的jar包
1.配置文件:applicationContext-service.xml(包扫描器,扫描带有@Service注解的类)
2.事务配置:配置文件:applicationContext-trans.xml
配置一个事务管理器,配合tx,配置切面。
表现层:使用SpringMVC 使用的JAR包:使用SpringMVC和Spring的JAR包
配置文件:1.springmvc.xml 2.配置注解驱动和视图解析器以及包扫描器(扫描Controller)
web.xml中:
1.配置SpringMVC的前端控制器 2.Spring容器初始化的listener
由于方便起见,就在一个配置文件中配置了(具体拆分看自己吧,哈哈哈,不完整以后再来补充)
