我连接到数据库服务器时出错。

这是我的application.properties，没有用户名和密码：

spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://159.65.200.68:3306/timYcreateDatabaseIfNotExist=true&useUnicode=true&useJDBCCompliantTimezoneShift=true&autoReconnect=true&useLegacyDatetimeCode=false&serverTimezone=UTC


spring.jpa.hibernate.naming_strategy=org.hibernate.cfg.EJB3NamingStrategy
spring.jpa.database-platform=org.hibernate.dialect.MySQL5Dialect
spring.jpa.hibernate.show_sql=true
spring.jpa.hibernate.ddl-auto=create-drop

这是错误：

java.sql.SQLNonTransientConnectionException: Could not create connection to database server. Attempted reconnect 3 times. Giving up.

如您所见，我得到ArrayIndexOutOfBoundsException。我不知道在这种情况下这是什么。我试过不同的方言，比如InnoDB，MySql5等等，没什么用。

非常感谢帮助！提前致谢

答案 0 :(得分：0)

更改数据库网址的属性： - 

spring.datasource.url=jdbc:mysql://159.65.200.68:3306/timY?createDatabaseIfNotExist=true

这里需要注意的是，db name是timY :-)并添加你在问题中提到的属性

答案 1 :(得分：0)

解决了它。将MySQL版本从6更改为5.然后收到明确的消息。显然用户不允许外部主机，所以我配置了mySql服务器。在此之后我改回到6.0.5并且一切正常。
