ssm框架集成步骤

步骤

1. 导包

2. 配置spring核心配置文件

1. Jdbc.properties
2. dataSource
3. SqlSessionFactory
4. dao
5. service
6. 事务

3.controller层

4.springMvc核心配置文件的配置

1. 扫描包
2. 静态资源放行
3. 开启springMvc注解的支持
4. 视图解析器

5.web.xml

1. 启动spring容器
2. 启动springMvc的容器
3. 解决Pos 提交乱码的问题

2.jdbc.properties

#如果数据库不存在就会自动创建ssm?createDatabaseIfNotExist=true
jdbc.username=root
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql:///ssm?createDatabaseIfNotExist=true
jdbc.password=1234
