mybatis plus官方文档地址:https://mp.baomidou.com/  
1.简单得springboot项目搭建  
1.1引入springboot父工程spring-boot-starter-parent,spring-boot-starter,spring-boot-starter-test

1.2引入mybatis plus依赖

2.springboot启动类,添加@mapperscan注解,注解作用:扫描的Mapper类的包的路径

3.编写实体类,并添加注解(数据库建表部分不多说了),这里讲三个注释,@TableName表名注释@TableId主键注释@TableField字段注释,详细内容及注解见https://mp.baomidou.com/guide/annotation.html\#tablename,然后写dao,mapper.xml,service,serviceImpl,controller

注:不想手动写可以用代码生成器,官网给的AutoGenerator :https://mp.baomidou.com/guide/generator.html\#%E4%BD%BF%E7%94%A8%E6%95%99%E7%A8%8B,也可以自己去搜code-generator,自己写规则  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2phdmFYaW5nemhl_size_16_color_FFFFFF_t_70 3]  
4.CRUD接口封装,接口看自己项目需求添加:https://mp.baomidou.com/guide/crud-interface.html\#mapper-crud-%E6%8E%A5%E5%8F%A3

![在这里插入图片描述][20190722104525906.png]6.service  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2phdmFYaW5nemhl_size_16_color_FFFFFF_t_70 6]7.serviceImpl
