Is it possible to map Hibernate <component> column to a custom user type?
I have defined a custom user type that works fine when used properties of my entities. For instance:
<class name="com.my.sample" table="MY_TABLE">
...
<property name="foo" type="myCustomUserType">
</class>
I'm needing something like this:
<class name="com.my.sample" table="MY_OTHER">
...
<component name="myAddress" class="com.my.sample.Address">
<property name="street" column="MY_OTHER_ADRR_STREET" 开发者_JAVA百科/>
<property name="foo" type="myCustomUserType" column="MY_OTHER_ADRR_COLUMN" />
</component>
</class>
Obviously, I'm supposing that myCustomUserType
is properly defined in the .HBM file. Is it possible to map a <component>
property like this?
Actually, it works fine. It is also possible to map <component>
properties using relationships such as <many-to-one>
. The mapping was somethig like this:
<component name="myAddress" class="com.my.sample.Address" >
<property name="aSimpleDate" column="TBL_ADDR_SIMPLE_DATE" type="date" />
<many-to-one class="OtherClass" name="otherClass" >
<column name="TBL_ADDR_OTHER_CLASS_ID" precision="9" scale="0"/>
</many-to-one>
<property name="foo" column="TLB_ADDR_FOO" type="myCustomUserType" />
</component>
Unfortunatelly, the Hibernate documentation is not very obvious about this.
