[SolitaryRain]

druid-spring-boot-starter:1.1.21 mysql-connector-java:5.1.46 配置 url: jdbc:mysql://xxxx（脱敏处理）:3306/xxxxx（脱敏处理）?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC&allowPublicKeyRetrieval=true&verifyServerCertificate=false&useSSL=false&autoReconnect=true&failOverReadOnly=false driver-class-name: com.mysql.jdbc.Driver username: xxxxxx（脱敏处理） password: xxxxxx（脱敏处理） initial-size: 10 max-active: 50 min-idle: 10 max-wait: 60000 pool-prepared-statements: true max-pool-prepared-statement-per-connection-size: 20 validation-query: SELECT 1 FROM DUAL test-on-borrow: true test-on-return: false test-while-idle: true time-between-eviction-runs-millis: 60000 filters: stat,wall

以下报错信息大概在10分钟出现一次。尝试很多办法都为解决。请问druid是否有关解决方案？ 2020-08-22 02:10:06,338 ERROR [Druid-ConnectionPool-Create-534666530] c.alibaba.druid.pool.DruidDataSource [DruidDataSource.java : 2755] create connection SQLException, url: jdbc:mysql://xxxxx（脱敏处理）:3306/xxxx（脱敏处理）?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC&allowPublicKeyRetrieval=true&verifyServerCertificate=false&useSSL=false&autoReconnect=true&failOverReadOnly=false, errorCode 0, state 08001 com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Could not create connection to database server.
