注意看上边报错信息中的红色字体部分，刚开始出现这个错误的时候我复制报错信息在百度上各种搜，结果答案都不对，后来请教我们项目组的大神，单独复制的红色字体部分去百度一搜就出来了相应的答案，所以说，报错信息一大堆未必都有用，找到关键点才是解决错误的关键，在通过本篇文章解决错误之前，应先确定MyBatis配置文件中的数据库名、用户名、密码都正确，打开CMD输入 mysql -u [用户名] -p 回车后输入密码，以判断密码是否正确，建议先把数据库配置一下环境变量，否则通过cmd命令打开的数据库的时候还要切到mysql文件下的bin目录下才行，太麻烦，关于配置数据库环境变量的教程百度一搜一大堆，这里就不一一阐述了，回归正题：

解决步骤：

1. 打开MySQL目录下的my.ini文件，若找不到数据库安装目录也可以全局搜索 my.ini，用记事本打开即可，在[mysqld] 标签下添加“skip-grant-tables”，保存并关闭文件，如图：
2. 通过services.msc命令进入本地服务列表，重启MySQL服务。
3. 通过命令行进入MySQL的BIN目录（若已经配置过环境变量直接输入“mysql -u root -p”即可），输入“mysql -u root -p”(不输入密码)，回车即可进入数据库。
4. 执行“use mysql;”，使用mysql数据库。
5. 执行“update user set password=PASSWORD(“password”) where user=’root’;”（修改root的密码），这里要格外说一下，因为我的数据库是新版的，所以用刚才的命令修改是报ERROR的，行不通，只能通过下面命令进行修改，这里被坑了好久，“update mysql.user set authentication_string=password('password') where user='root' and Host = 'localhost';”
6. 打开MySQL目录下的my.ini文件，删除最后一行的“skip-grant-tables”，保存并关闭文件.
7. 通过services.msc命令进入本地服务列表，重启MySQL服务。

8. 在命令行中输入“mysql -u root -p”，回车输入“password”即可成功连接数据库。

9. 上述步骤完事之后本以为可以成功连接了，却没想到又出现了新的错误，先上报错信息看一下：Thu Mar 22 16:06:58 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.
10. 百度一搜，只需要改一下MyBatis配置文件中的url即可，改后如图：

    url: jdbc:mysql://localhost:3306/user?useSSL=false&useUnicode=true&characterEncoding=UTF-8

11. 好了，程序正常运行，本人刚入行不久，小菜鸟一枚，哪里有不对的，还请各位大神们多多指教，不胜感激！
