hibernate.properties
connection.driver_class=com.mysql.jdbc.Driver
connection.url=jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=UTF-8
connection.username=root
connection.password=1234

报错信息:

    可以尝试通过如下几个方面检查:
    1) 检查密码是否正确;
    2) 命令行方式登陆一下mysql,看看是否可以正常登陆。
    3) 如果命令行可以登陆,建议查询一下root用户授权。 看看是不是运行root 在localhost上登陆。
