使用eclipse连接mysql报错WARN:EstablishingSSLconnectionwithoutserver'sidentityverificationisnotre

错误信息如下&＃xff1a;&＃xff08;一共两个错误&＃xff0c;此贴只能解决第一个错误&＃xff0c;访问被拒绝没有解决&＃xff09;
WARN: Establishing SSL connection without server’s identity verification is not recommended. According to MySQL 5.5.45&＃43;, 5.6.26&＃43; and 5.7.6&＃43; 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&＃61;false, or set useSSL&＃61;true and provide truststore for server certificate verification. java.sql.SQLException: Access denied for user ‘root’&＃64;‘localhost’

一&＃xff1a;是在警告:不建议在没有服务器身份验证的情况下建立SSL连接。根据MySQL 5.5.45&＃43;、5.6.26&＃43;和5.7.6&＃43;的要求&＃xff0c;如果没有设置显式选项&＃xff0c;则默认情况下必须建立SSL连接。您需要通过设置useSSL&＃61;false显式禁用SSL&＃xff0c;或者设置useSSL&＃61;true并为服务器证书验证提供信任存储。

二&＃xff1a;java.sql。SQLException:用户“root”&＃64;“localhost”被拒绝访问

问题一解决办法是在url中添加useSSL&＃61;false

//URL指向要访问的数据库test
String url &＃61; “jdbc:mysql://localhost:3306/test?useSSL&＃61;false”;
保存&＃xff0c;再运行程序就没有警告了。
