<element> vs <composite-element> in Hibernate


<element> vs <composite-element> in Hibernate

hope this fix your issue is used when you want to map a collection of "simple" values. See this example from 6.2.4. Collections of values and many-to-many associations
code :
<set name="names" table="person_names">
    <key column="person_id"/>
    <element column="person_name" type="string"/>
</set>
<set name="someNames" table="some_names" lazy="true">
    <key column="id"/>
    <composite-element class="eg.Name"> <!-- class attribute required -->
        <property name="initial"/>
        <property name="first"/>
        <property name="last"/>
    </composite-element>
</set>

wish of those help No, you need a no argument constructor. Hibernate needs a way to create objects.
You might be able to create a subclass of this class, and give the subclass the no-arg constructor.

wish help you to fix your issue I have a composite element in my hibernate mapping that I need to show up in hibernate's classmetadata dictionary. The only way I have been able to accomplish this is to define the class in a separate entry, and use . , I ended up having to redesign.

Does that help I only ever used composite keys which are references to other tables, but take a look at that one JPA Composite Key + Sequence
At first seems like bad news, but if you read the comments of the accepted answer you may get lucky

Does that help So, finally it was a bit of a stupid issue. If I do not save attribute first and since there is no set on the attribute side to manage the link between form and attribute, the composite element was not saved. Saving the new attributes first, then saving the form fixed my issue.

this one helps. Found solution: I manually stored data from composite element, like that
CPUser user = userService.getCPUser(id);
code :
for (CPUserRights rights : user.getUserRights()) {
    rights.setRight(2);

    userRightService.updateCPUserRights(rights);
}
