- build.gradle에 있는 dependencies에 mybatis를 추가(mysql 컨낵터가 없다면 이것도 추가)
//mysql-connector :
runtimeOnly 'com.mysql:mysql-connector-j'
//mybatis :
implementation 'org.mybatis.spring.boot:mybatis-spring-boot-starter:2.2.0'

Description:
Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.
Reason: Failed to determine a suitable driver class
Action:
Consider the following:
If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).
- application.properties에 붙여넣기
spring.datasource.driver=com.mysql.cj.jdbc.Driver
spring.datasource.jdbc-url=jdbc:mysql://localhost:3306/데이터베이스이름?&serverTimezone=UTC&autoReconnect=true&allowMultiQueries=true&characterEncoding=UTF-8
spring.datasource.username=계정이름
spring.datasource.password=계정비번
spring.datasource.mapper-locations=classpath:/mapper/*.xml
