Hibernate错误：java.sql.SQLException：用户'root'@'localhost'拒绝访问（使用密码：YES）

Question

我是初学者。当我在eclipse中使用hibernate时，它会显示：

  

错误：用户'root'@'localhost'拒绝访问（使用密码：   是）org.hibernate.exception.GenericJDBCException：无法打开   连接

我是初学者。请帮助我，我不知道什么是错的，我不会通过互联网找到合适的答案或者我的项目的堆栈溢出的其他答案。

这是我的代码：

hibernate.properties：

 hibernate.connection.driver_class = com.mysql.jdbc.Driver

    hibernate.connection.url = jdbc:mysql://127.0.0.1:3306/db_test

    hibernate.connection.username = root            

    hibernate.connection.password = root

    hibernate.show_sql=true

    hibernate.dialect = org.hibernate.dialect.MySQLDialect

hibernate.cfg.xml中：
