本文详细介绍了如何在Spring Boot项目中整合MyBatis，包括配置数据源、SqlSessionFactory、Mapper扫描以及相关XML配置。项目结构清晰，展示了从web.xml到各配置文件的完整设置，为读者提供了一个完整的Spring Boot与MyBatis集成示例。

mapper

xxxMapper.xml:

<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="">

</mapper>
