spring5x-mybatis-plus

宇宙小神特别萌
spring5x-mybatis-plus此模块是从spring5x-mybatis-base 基础模块扩展过来的
spring5x-mybatis-base模块是一个mybatis架构
如果没有搭建spring5x-mybatis-base模块，请先参考： spring5x-mybatis-base模块搭建
Spring5x-mybatis-base 是一个mybatis基础模块，今后的spring+mybatis 的xml配置方式，在此模块上扩展。
搭建项目
基于Spring5x-mybatis-base 基础模块 新增功能：
- 1、集成 druid/c3p0 + mysql/oracle
- 2、集成 Mybatis-Plus 配置
- 3、mapper 配置：
- mybatis 增删改查操作
- 动态(trim) 插入数据
- mybatis+mysql 批量插入数据
- mybatis+oracle 批量插入数据
- 4、Mybatis-PageHelper 分页插件
- 5、项目启动自动执行sql文件
注:mybatisPlus 是对mybatis的封装，但是并没有更改底层的东西，所有完整保留mybatis配置方式，也就是说mybatis的所有配置几乎都可用。
1、集成 druid/c3p0 + mysql/oracle

接口测试：
- 1、直接使用浏览器调用接口传参
- 2、使用postman工具
- 3、使用swagger api 测试(此项目引入了swagger)
druid测试：
- 访问：http://localhost:8080/项目路径/druid/index.html
