Java连接Mysql数据库警告：Establishing SSL connection without server's identity

Java连接Mysql数据库警告：Establishing SSL connection without server’s identity verification is not recommend

Java连接MySQL出现如下警告：

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.

原因:

连接数据库的jar包版本过低，与数据库不匹配。

解决方法：

方案一：跟换高版本的java-connector-mysql的jar包。

方案二：在mysql连接字符串url中加入ssl=true或者false即可，如下所示。

url=jdbc:mysql://127.0.0.1:3306/framework?characterEncoding=utf8&useSSL=true

java连接mysql数据库，如果配置信息没有出错，一般都是jar包的问题，jar包算坏或者版本不对，跟换jar包即可。
