-----------------------------------------
Summary: Property and referential constraint are missing when
@ManyToOne(fetch = EAGER)
Key: OLINGO-1242
URL: https://issues.apache.org/jira/browse/OLINGO-1242
Project: Olingo
Issue Type: Bug
Components: odata2-jpa
Affects Versions: V2 2.0.10
Environment: Java EE 7 (TomEE) Server, Java 8, EclipseLink 2.5.2
Reporter: Nikolay Grechanov
In my JPA model I have the following property:
{code:java}
@ManyToOne(fetch = EAGER, optional = false)
@BatchFetch(JOIN)
@NotNull
@JoinColumn(name = "PARENT_ID", nullable = false)
@JsonProperty(PARENT_DETAILS)
@JsonSerialize(using = ODataDeferredSerializer.class)
private Parent parent;{code}
$metadata contains Parent property as well as referential constraint for
association:
{code:java}
...
<EntityType Name="Child">
<Key>
<PropertyRef Name="Id"/>
</Key>
<Property Name="Parent" Type="Edm.Int64" Nullable="false"/>
<NavigationProperty Name="ParentDetails"
Relationship="myProject.Child_Parent_Many_One0" FromRole="Child"
ToRole="Parent"/>
</EntityType>
...
<Association Name="Child_Parent_Many_One0"> <End Type="myProject.Child"
Multiplicity="*" Role="Child"/> <End Type="myProject.Parent" Multiplicity="1"
Role="Parent"/> <ReferentialConstraint>
<Principal Role="Parent">
<PropertyRef Name="Id"/>
</Principal>
<Dependent Role="Child">
<PropertyRef Name="Parent"/>
</Dependent>
</ReferentialConstraint>
</Association>
...{code}
When I set
{code:java}
@ManyToOne(fetch = LAZY, optional = false){code}
then $metadata contains _neither_ Parent property _nor_ referential constraint
for the association:
{code:java}
...
<EntityType Name="Child">
<Key>
<PropertyRef Name="Id"/>
</Key>
<NavigationProperty Name="ParentDetails"
Relationship="myProject.Child_Parent_Many_One0" FromRole="Child"
ToRole="Parent"/>
</EntityType>
...
<Association Name="Child_Parent_Many_One0"> <End Type="myProject.Child"
Multiplicity="*" Role="Child"/> <End Type="myProject.Parent" Multiplicity="1"
Role="Parent"/>
</Association>
...{code}
ManyToOne.optional, NonNull, JoinColumn.nullable annotation values have no
effect
