休眠 - 无法连接到数据库 [英] Hibernate - Cannot connect to DB

问题描述

我尝试使用mysql，所以包括mysql.jdbc，这些都是我的hibernate设置。

I try to use mysql so include mysql.jdbc and these are my hibernate settings.

<?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
    <hibernate-configuration>
      <session-factory>
        <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
        <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/TekirMobile</property>
        <property name="hibernate.connection.username">root</property>
        <property name="hibernate.connection.password">fenderpass</property>
        <property name="hibernate.show_sql">true</property>
        <property name="hibernate.current_session_context_class">thread</property>
        <property name="hibernate.query.factory_class">org.hibernate.hql.classic.ClassicQueryTranslatorFactory</property>
      </session-factory>
    </hibernate-configuration>

但是当我尝试connecto db时，我得到这个错误：

but when i try to connecto db i get this error:

Unable to connect: Cannot establish a connection jdbc:mysql://localhost:3306/mydbname using apache.org.derby.jdbc.ClientDriver(Unable to find a suitable driver)

我甚至不使用derby为什么我得到这个错误？

I dont even use derby why i get this error?

推荐答案

您没有在任何地方指定连接驱动程序。它告诉你它正在尝试使用 apache.org.derby.jdbc.ClientDriver 进行连接。

You are not specifying the connection driver anywhere. It is telling you it's trying to connect using apache.org.derby.jdbc.ClientDriver.

以下列方式指定MySQL驱动程序：

Specify the MySQL driver, in the following way:

<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
