【问题描述】:
我在我的 Mac 上运行 VirtualBox,带有一个 IP 地址为 192.168.56.15 的仅限主机的网络适配器。我已将VM的IP地址设置为192.168.56.107。
Host : MacOs High Sierra
Guest VM: Ubuntu
我已经在 VM 上安装并配置了一个 mysql 数据库,并且我已经将用户 appuser 设置为可以远程访问该数据库。
现在,在我的 Mac 上,当我尝试运行 springboot 应用程序时,我在 eclipse 中运行了一个 sprintboot 应用程序。我收到以下错误。

Fri Sep 29 14:43:12 BST 2017 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.

为什么会出现这个错误?我已经指定了所有正确的值。这是我的 application.properties 文件。 注意错误中的IP是VirtualBox中host-only适配器的IP。
spring.datasource.url=jdbc:mysql://192.168.56.107:3306/appdatabase
spring.datasource.data-username=appuser
spring.datasource.data-password=******
spring.datasource.dbcp2.test-while-idle=true
spring.datasource.dbcp2.validation-query=SELECT 1
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=create
spring.jpa.hibernate.naming.strategy=org.hibernate.cfg.ImprovedNamingStrategy
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
如何解决此错误?
