------解决思路----------------------
本地的话应该是 数据库用户名，密码有错
------解决思路----------------------
Access denied for user 'root'@'localhost' (using password: YES) 数据库连接没有通过。
------解决思路----------------------

------解决思路----------------------
数据库的用户名、密码有误，可以用客户端试试，没问题再java。
------解决思路----------------------
Access denied for user 'root'@'localhost' (using password: YES)
密码错了，使用本地数据库客户端工具直接连接数据库，验证密码。
------解决思路----------------------
通过报错信息来看，是数据库未成功连接，你可以重新创建用户尝试下
------解决思路----------------------
用的是root用户么？
