篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了spring+springmvc+mybatis配置文件相关的知识，希望对你有一定的参考价值。
最近在学习SSM,自己上手了一个crm项目，这两天对底层配置文件做了个总结。
sqlmapconfig.xml
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> <!-- 全局setting配置，根据需要添加 --> <!-- 配置别名 --> <typeAliases> <!-- 批量扫描别名，指定pojo类的位置,该配置中暂时用不到 --> <package name="cn.itcast.ssm.po"/> </typeAliases> <!-- 配置mapper 由于使用spring和mybatis的整合包进行mapper扫描，这里不需要配置了。 必须遵循：mapper.xml和mapper.java文件同名且在一个目录 --> <!-- <mappers> </mappers> --> </configuration>
applicationContext.xml
把spring-mybatis.xml文件和spring-service.xml文件整合在一起
