java - 스프링 툴 스위트와 MySQL을 연결할 수 없습니까?

톰캣 포트와 mysql 포트가 같아야합니까? rest-apis를 통해 mysql 데이터베이스에 액세스하고 싶습니다. mysql Workbench를 열고 스프링 부팅을 동시에 실행할 수 없습니다. 둘 다 동일한 포트를 사용하고 있기 때문입니까? 또한 application.properties에서 포트 "server.port = 7070"을 변경하면 프로젝트가 성공적으로 실행되지 않습니다.

application.properties :

spring.datasource.url=jdbc:mysql://localhost:3306/playjava?useSSL=flase
spring.datasource.username=root
spring.datasource.password=root
spring.jpa.show-sql=true
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
server.port=3306
