整合ssm框架

1.1 整合的思路

一、Dao层:整合mybatisspring

需要的jar包:

1、mybatisjar

2、Mysql数据库驱动

3、数据库连接池

4、Mybatisspring的整合包。

5、Springjar

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SqlSessionFactorymybatisspring整合包中的)

4、配置mapper文件的扫描器。

 

二、Service层:

使用的jar包:springjar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springmvcspringjar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
