【问题描述】：

这是我的配置文件：

<hibernate-configuration>
    <session-factory>
        <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="hibernate.connection.password">12345</property>
        <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/test</property>
        <property name="hibernate.connection.username">root</property>
        <property name="hibernate.format_sql">true</property>
        <property name="hibernate.show_sql">true</property>
        <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
        <property name="hibernate.hbm2ddl.auto">create</property>
        <mapping class= "com.egen.UserDetails" />
    </session-factory>
</hibernate-configuration>

我得到的错误是：

【问题讨论】：

Caused by: java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: YES) 那么有什么问题呢？

标签： java mysql hibernate

【解决方案1】：

问题在于用户root的权限。您必须在命令提示符下为您的 MySQL 设置授权和配置一些设置。请尝试以下链接。

1.) MySQL Access denied errors

2.)Grant Privileges for local user root

这基本上是一个特权问题。解决这个问题，它就会得到修复。

希望对您有所帮助。 :)

【解决方案2】：

您应该检查您为 root 提供的密码是否正确。或者可能是用户身份验证根无权访问数据库。
