spring boot整合mybatis
咳咳,之前的目录结构还在吧?不在了?那你自己的创建吧,继续spring boot整合mybatis!
按照一般SSM标准项目,项目结构如下,比较正规的项目,可能还会将实体和业务层接口独立出来作为一个服务jar包,此处省略,效果是一样的,有不懂的可以私聊我
数据库怎么创建我就不教了,此处省略数据库(Mysql)安装,链接
SQL语句:
CREATE TABLE `tb_favorite` (
`id` bigint(16) unsigned NOT NULL AUTO_INCREMENT COMMENT '主键',
`product_id` bigint(16) unsigned DEFAULT NULL COMMENT '商品编号',

`status` int(1) DEFAULT NULL COMMENT '状态：1-收藏，2-取消收藏',

} 每个代码的具体实现和普通的spring项目代码没有区别,唯一的区别
1:pom.xml文件,需要加入依赖,具体如下:
org.mybatis.spring.boot
mybatis-spring-boot-starter
1.1.1
mysql
mysql-connector-java
mysql-connector-java:数据库驱动
2:src/main/resources/application.properties需要加入数据库以及mybatis相关的配置,我比较中意key-value的方式,符合我们之前的习惯,yml的方式,就此忽略掉了,有需要了解的另行百度
注:一下配置根据自行情况更改,如跟着我做的,只需要更改datasource相关即可
#数据库配置文件
spring.datasource.url=jdbc:mysql://localhost:3306/xyy_v2?useUnicode=true&characterEncoding=utf8&allowMultiQueries=true
spring.datasource.username=admin
spring.datasource.password=admin
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
#mybatis配置文件
mybatis.mapperLocations=classpath:com/xyy/mapper/*Mapper.xml
mybatis.type-aliases-package=com.xyy.model同样右键运行main主入口,浏览器访问
