ssm整合配置文件

1. 导入jar包
2. 编写配置文件
3. 编写代码

 

---

applicationContext-dao.xml---配置数据源、SqlSessionFactory、mapper扫描器

applicationContext-service.xml---配置service接口

applicationContext-transaction.xml--事务管理

sprintmvc.xml---springmvc的配置，配置处理器映射器、适配器、视图解析器

SqlMapConfig.xml---mybatis的配置文件，配置别名、settings、mapper

1 编写SqlMapConfig.xml---mybatis文件

<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>

	<!-- 定义 别名 -->
	<typeAliases>
		<!-- 批量别名定义 指定包路径，自动扫描包下边的pojo，定义别名，别名默认为类名（首字母小写或大写） -->
		<package name="实体类包路径" />

	</typeAliases>



</configuration>
