本文介绍如何解决MySQL数据库连接中出现的字符集不匹配问题，包括修改连接字符串和调整mybatis配置文件，以及可能需要删除不兼容的驱动程序。

连接mysql数据库
String url = “jdbc:mysql://localhost:3306/db?useUnicode=true&characterEncoding=utf8”;
改成这句

如果上面方法不可以，删除 \WebContent\WEB-INF\lib目录下的mysql-connector的jar文件。
原因是：MySQL驱动和数据库字符集设置不搭配

mybatis配置文件连接

配置文件修改：jdbc:mysql://localhost:3306/ssm?useUnicode=true&characterEncoding=utf8
