springboot 項目 mysql: WARN: Establishing SSL connection without servers identity verification is no

項目啓動mysql 會有警告,如下:

WARN: Establishing SSL connection without server’s identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn’t set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to ‘false’. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.

翻譯爲爲:
請注意:不建議在沒有服務器身份驗證的情況下建立SSL連接。根據MySQL 5.5.45+、5.6.26+和5.7.6+的要求，如果不設置顯式選項，則必須建立默認的SSL連接。您需要通過設置useSSL=false顯式地禁用SSL，或者設置useSSL=true併爲服務器證書驗證提供信任存儲

解決辦法:
jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=utf-8&useSSL=false
即可
