Answer 1

Person.hbm.xml 配置写错了<hibernate-mapping>
  <class name="com.xt.Person" table="PERSON" schema="SYSTEM">
  <id name="id" type="java.lang.Long" column="ID" unsaved-value="0">
  <generator class="foreign">
  <param name="property">passport</param>
  </generator>
  </id>
  <one-to-one name="passport" class="com.xt.Passport" constrained="true" cascade="all"/>  
  <property name="name" type="java.lang.String">
  <column name="NAME" length="20" />
  </property>
  <property name="age" type="java.lang.Long">
  <column name="AGE" precision="22" scale="0" />
  </property>
  </class>
</hibernate-mapping>
