问题描述
<hibernate-mapping><classname="code.User"table="user"catalog="sample"discriminator-value="notnull"><idname="id"type="java.lang.Integer"><columnname="Id"/><generatorclass="identity"/></id><propertyname="age"type="int"><columnname="age"not-null="true"/></property><propertyname="firstname"type="string"><columnname="firstname"length="20"not-null="true"/></property><propertyname="lastname"type="string"><columnname="lastname"length="20"not-null="true"/></property><discriminatorcolumn="type"type="int"not-null="true"/><subclassname="code.AddressUser"discriminator-value="0"><propertyname="address"column="address"/><propertyname="zipcode"column="zipcode"/></subclass><subclassname="code.TelUser"discriminator-value="1"><propertyname="tel"column="tel"/></subclass></class></hibernate-mapping>当我一添加discriminator就报错Thecontentofelementtype"class"mustmatch
解决方案
解决方案二：
贴个示例你看下<classname="cn.com.leadfar.oa.model.Party"table="t_party"discriminator-value="X"><idname="id"><generatorclass="native"/></id><discriminatorcolumn="party_type"type="char"></discriminator><propertyname="name"/><propertyname="description"/><many-to-onename="parent"column="pid"/><setname="children"lazy="extra"inverse="true"order-by="id"><keycolumn="pid"/><one-to-manyclass="cn.com.leadfar.oa.model.Party"/><filtername="no_contain_person"condition="party_type!='P'"></filter></set><subclassname="cn.com.leadfar.oa.model.Company"discriminator-value="C"><propertyname="tel"/><propertyname="fax"/><propertyname="address"/><propertyname="postcode"/><propertyname="site"/><propertyname="email"/><propertyname="industry"/></subclass><subclassname="cn.com.leadfar.oa.model.Department"discriminator-value="D"><propertyname="tel"/><propertyname="snumber"/></subclass><subclassname="cn.com.leadfar.oa.model.Person"discriminator-value="P"><propertyname="snumber"/><propertyname="sex"/><propertyname="phone"/><propertyname="duty"/><propertyname="address"/><propertyname="qq"/><propertyname="msn"/><propertyname="email"/><one-to-onename="user"/></subclass><subclassname="cn.com.leadfar.oa.model.Position"discriminator-value="S"></subclass></class><filter-defname="no_contain_person"></filter-def>
解决方案三：
都指明type="int"为什么discrimintor-value=""notnull"
解决方案四：
找到原因了，把discriminator放在定义id的后面就可以了
