WARN: Establishing SSL connection without server's identity verification is not recommended. setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.

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.

本编文章的报错为  wiki中catalina.out 报警处理：

解决过程：

在配置文件中  连接数据库的url中 添加useSSL=false ：

 vim /var/atlassian/application-data/confluence/confluence.cfg.xml

   <property name="hibernate.connection.url">jdbc:mysql://127.0.0.1:3306/confluence</property>

修改为

  /etc/init.d/confluence restart 重启即可
