休眠-无法连接到数据库

Question

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>

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)

I dont even use derby why i get this error?

Answer 1

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

Specify the MySQL driver, in the following way:

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