解决程序连接mysql警告-Establishing SSL connection without server's identity verification is not recommended.

spring boot连接mysql8.0控制台输出警告：

Mon May 17 09:38:23 CST 2021 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.

翻译：
警告:不建议在没有服务器身份验证的情况下建立SSL连接。MySQL 5.5.45+、5.6.26+和5.7.6+要求如果没有设置显式选项，默认情况下必须建立SSL连接。为了符合未使用SSL的现有应用程序，verifyServerCertificate属性被设置为“false”。您需要通过设置useSSL=false显式禁用SSL，或者设置useSSL=true并为服务器证书验证提供信任库。

解决办法：
1、建立ssh连接
2、配置文件的url后加useSSH=false
system.datasource.druid.url=jdbc:mysql://10.50.24.8:3306/test_db?useUnicode=true&characterEncoding=utf-8&zeroDateTimeBehavior=convertToNull&useSSL=false

useSSL=false作用：

MySQL在高版本需要指明是否进行SSL连接

1.true 需要连接
2.false 不需要连接
