1.what's mybatis?

MyBatis 是一款优秀的持久层框架，它支持定制化 SQL、存储过程以及高级映射。MyBatis 避免了几乎所有的 JDBC 代码和手动设置参数以及获取结果集。MyBatis 可以使用简单的 XML 或注解来配置和映射原生类型、接口和 Java 的 POJO（Plain Old Java Objects，普通老式 Java 对象）为数据库中的记录。

2.what's mybatis-spring-boot-starter?

MyBatis-Spring-Boot-Starter可帮助您在Spring Boot之上快速构建MyBatis应用程序。

通过使用此模块，您将实现：

• 构建独立应用程序
• 将样板减少到几乎为零
• 更少的XML配置

3.how?

• pom

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.transaction.annotation.EnableTransactionManagement;

简单介绍一下本项目用到了哪些，看pom文件即可

• 日志管理logback
• 持久层框架mybatis
• 模板引擎Thymeleaf
• 数据源Druid
• pagehelper分页

properties相关配置已加入注释

相关测试请参考demo

实现的功能很简单，没有太复杂的配置，尽量做到简单。

Druid附带监控，酌情配置。
