1、pom文件加入依赖
<!--加入mybatis依赖-->
<!--引入satrter-->
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>2.1.2</version>
</dependency>
<!--mysql的jdbc驱动-->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<scope>runtime</scope>
</dependency>
<!--引入第三方数据源-->
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid</artifactId>
<version>1.1.8</version>
</dependency>
2、application.properties配置文件
#===============================数据库相关======================================
#数据库驱动(可以自动识别)
#spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/databaseName?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC
spring.datasource.username=username
spring.datasource.password=password
#修改数据源(com.zaxxer.hikari.HikariDataSource)
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
useUnicode=true&characterEncoding=UTF-8:防止中文乱码
serverTimezone=UTC:设置时间,UTC是世界标准时间
未设置时间报数据库连接错误:The server time zone value '�й���ʱ��' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration
3、添加mapper扫描
4、开发mapper
