<!DOCTYPE hibernate-configuration PUBLIC

"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-mapping>
<class name="com.test.set.Users" table="USERS" schema="test1">
<id name="id" column="ID" type="int">
<generator class="increment"/>
</id>
<property name="username" type="java.lang.String">
<column name="NAME" length="50"></column>
</property>
<property name="age" type="int">
<column name="AGE"/>
</property>
<set name="images" table="IMAGES" lazy="true">
<key column="USERID"/>
<element column="FILENAME" type="string" not-null="true"/>
</set>
</class>
</hibernate-mapping>
为什么property行会报错multiple markers at this line -Attribute''type'' must be declared for element type "property"
运行后抛异常
