部署mysql版本項目問題記錄
一,com.mysql.cj.jdbc.exceptions.CommunicationsException: Communications link failure報錯
將url從jdbc:mysql://localhost:3306/datashare?useUnicode=true&characterEncoding=utf-8&useSSL=true改為
jdbc:mysql://localhost:3306/datashare?autoReconnect=true&useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=CONVERT_TO_NULL&useSSL=false&serverTimezone=UTC
二,The connection property ‘zeroDateTimeBehavior‘ only accepts values of the form: ‘exception‘, ‘round‘ or ‘convertToNull‘. The value ‘CONVERT_TO_NULL‘ is not in this set.報錯
具體信息為:
The connection property ‘zeroDateTimeBehavior‘ only accepts values of the form: ‘exception‘, ‘round‘ or ‘convertToNull‘. The value ‘convertToNull ‘ is not in this set.
將zeroDateTimeBehavior=CONVERT_TO_NULL改為zeroDateTimeBehavior=convertToNull
三,mysql查詢時表名大寫的時候報錯Table ‘datashare.TEST‘ doesn‘t exist
用 root 登錄，修改 /etc/my.cnf （註意：以實際 my.cnf 配置文件路徑為準）
在 [mysqld] 節點下，加入一行： lower_case_table_names=1（0:大小寫敏感;1:大小寫不敏感）
重啟 MySQL 即可；
