# springboot-tkmybatis

#### 介绍
学习demo

流程
1.pom引入jar

```
                <dependency>
			<groupId>tk.mybatis</groupId>
			<artifactId>mapper-spring-boot-starter</artifactId>
			<version>2.0.2</version>
		</dependency>

		<dependency>
			<groupId>mysql</groupId>
			<artifactId>mysql-connector-java</artifactId>
			<scope>runtime</scope>
		</dependency>
		<dependency>
			<groupId>com.alibaba</groupId>
			<artifactId>druid</artifactId>
			<version>1.0.20</version>
		</dependency>
```
2.配置文件

```
# 数据库连接
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/test?serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8
spring.datasource.username=root
spring.datasource.password=123456

# mybatis
mybatis.type-aliases-package=com.ways.mms.entity
mybatis.mapperLocations: classpath:mapper/*.xml
```


3.创建相应的实体类（数据库开头大写，驼峰命名）

4.创建dao接口，继承extends tk.mybatis.mapper.common.Mapper<CzqMybatis>

5.springboot的开始类上，加注解@MapperScan("com.ways.mms.dao")，不然不会引入

6.然后就可以直接用通用mapper的方法了
