我的Customer.hbm.xml文件如下：
<?xml version="1.0"?>
<hibernate-mapping>
<class name="Customer" table="CUSTOMER">
<id name="id" column="CID">
<gernerate class="increment"/>
</id>
<property name="username" column="USERNAME"/>
<property name="password" column="PASSWOED"/>
</class>
</hibernate-mapping>
报的错：
test hibernate!!
log4j:WARN No appenders could be found for logger (net.sf.hibernate.cfg.Environment).
log4j:WARN Please initialize the log4j system properly.
