java - hibernate4二级缓存报错org/slf4j/LoggerFactory not found

使用的是Hibernate4.3.11 + hibernate-ehcache-4.3.11.Final.jar + ehcache-core-2.4.3.jar + slf4j-log4j12-1.7.21.jar，新手麻烦大神看一下，如果信息提供的不够详细，拜托提示一下，我马上补充。

hibernate.cfg.xml

        <property name="connection.password">root</property>
        <property name="hibernate.current_session_context_class">thread</property>
    </session-factory>

</hibernate-configuration>

Students.hbm.xml

        <property name="sname" type="java.lang.String"/>
        <property name="gender" type="java.lang.String"/>

</hibernate-mapping>

ehcache.xml

    />
</ehcache>
