　　Thu Mar 22 14:47:41 CST 2018 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.

上一篇： “童养媳”是什么时候开始的？童养媳中的受害者！

下一篇：前端模块化：CommonJS，CMD，AMD，ES6

MyBatis 连接本地数据库拒绝访问错误：java.sql.SQLException: Access denied for user 'root

开发工具：IntelliJ IDEA 2017.3.4 x64

开发框架：SpringBoot + MyBatis

数据库版本：MySQL 5.7.20

先来看一下报错信息：

java访问数据库被拒绝，不能连接数据库ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

连接本地数据库出现：1045 - Access denied for user 'root'@localhost'(using pass

Eclipse使用jdbc连接MySql数据库报：java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: YES)
