SSM整合配置详解-优快云博客

配置步骤

1.1pom:Spring-context spring-webmvc spring-web

mysql druid Mybatis servlet spring-jdbc

mybatis-spring jquery

1.2WEB-INF/jsp/web.xml: spring监听器

前端控制器

懒加载

中文过滤器

1.3springmvc.xml: 开启spring注解扫描controller层

开启默认的处理器适配器和处理器映射器

视图解析器（前缀 后缀）

开放静态资源

1.4applicationContext.xml: 开启spring注解扫描但是不扫描controller

配置mybatis

引入jdbc文件

创建数据源（基本四项）

创建sqlsession（输入数据源，起别名，关联映射文件）

将sqlsession加载进spring容器中（指定容器 扫描包）

1.5 jdbc.properties:dir:驱动

Url:地址

Username:用户名

password：密码
