java - 即使 MySQL 服务器正在运行，也无法通过 Spring Boot 应用程序连接到 MySQL 服务器

标签 java mysql spring-boot

我的application.properties看起来像这样

spring.datasource.url=jdbc:mysql://localhost/bootdb2?createDatabaseIfNotExist=true&autoReconnect=true&useSSL=false&useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
spring.datasource.username=root
spring.datasource.password=password
spring.datasource.platform=mysql
spring.datasource.initialization-mode=always

错误信息:
