我想通过编写一个简单的java程序来学习Hibernate。我使用MySQL作为数据库,运行程序时出现上述错误。我在互联网上看到了很多这样的解决方案,并尝试尽一切可能无济于事。我究竟做错了什么?Eclipse - Hibernate:找不到适合jdbc的驱动程序:mysql:// localhost:3306/hibernatedb
配置文件:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/hibernatedb</property>
<property name="hibernate.connection.username">root</property>
<property name="hibernate.connection.password">root</property>

<property name="format_sql">true</property>
<property name="hbm2ddl.auto">create</property>
<mapping resource="com/test/hibernate/student.hbm.xml" />
</session-factory>
</hibernate-configuration>
控制台输出:
log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment).
log4j:WARN Please initialize the log4j system properly.
