更新： - 添加了application.properties

# LOCAL DATABASE
spring.datasource.url = jdbc:mysql://localhost:3306/test3?autoReconnect=true&useSSL=false
spring.datasource.username = root
spring.datasource.password = admin

# REMOTE DATABASE
#spring.datasource.url = jdbc:mysql://localhost:9090/test3
//in fact the address to the remote db is modraszka.sth.sth:8080
#spring.datasource.username = root
#spring.datasource.password = password
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
