1. upate-》create
<property name="hbm2ddl.auto">create</property>
2. 2.Mapping的映射文件有重名的，如：
<mapping resource="com/runsky/domain/Status.hbm.xml" /> <mapping resource="com/runsky/domain/Status.hbm.xml" />
3.表中有关键字，如：
order，level，address，degree等。
4.在配置文件中不小心写了两个同名属性，如：
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="org.hibernate.auction">
<class name="com.runsky.domain.AdditionalInformation"
table="AdditionalInformation" lazy="false">
<id name="id" column ="ID" length="32">
<generator class="uuid.hex"/>
</id>
<property name="tag" column ="tag" />
<property name="content" column ="content" />
<property name="id" column ="id" />
</class>
</hibernate-mapping>
5.全类名写错了
6. 自增长字段是String类型， 应该改成Long
