整合ssm框架

一、Dao层：整合mybatis和spring

需要的jar包：

1、mybatis的jar包

2、Mysql数据库驱动

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

1、数据源

2、数据库连接池

3、配置SqlSessionFactory（mybatis和spring整合包中的）

4、配置mapper文件的扫描器。

 

二、Service层：

使用的jar包：spring的jar包。

配置文件：applicationContext-service.xml

配置一个包扫描器，扫描所有带@Service注解的类。

事务配置：

配置文件：applicationContext-trans.xml

1、配置一个事务管理器

2、配置tx

3、配置切面

 

三、表现层

使用springmvc，需要使用springmvc和spring的jar包。

配置文件：springmvc.xml

1、配置注解驱动

2、配置一个视图解析器。

3、包扫描器，@Controller注解

 

Web.xml

1、配置springmvc的前端控制器

2、Spring容器初始化的listener。
