连接MySQL数据库时抛出警告：
Tue Feb 26 17:38:27 CST 2019 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.
这是Mysql数据库的SSL连接问题，提示警告不建议使用没有带服务器身份验证的SSL连接，是在MYSQL5.5.45+, 5.6.26+ and 5.7.6+版本中才有的这个问题

解决

在配置文件application.yml中连接数据库的url后添加useSSL=false即可

spring
  datasource:  
    driverClassName: com.mysql.jdbc.Driver
    url: jdbc:mysql://192.168.206.128:3306/tensquare_article?characterEncoding=utf8&useSSL=false
    username: root
    password: ....
