------------------------------------------
Summary: Olingo V4 client reports invalid value type for
`Edm.GeometryCollection` and `Edm.GeographyCollection` JSON values
Key: OLINGO-1392
URL: https://issues.apache.org/jira/browse/OLINGO-1392
Project: Olingo
Issue Type: Bug
Components: odata4-client
Reporter: Vladislav Glinskiy
Fix For: (Java) V4 4.7.0
Olingo V4 client reports value type for `Edm.GeometryCollection` and
`Edm.GeographyCollection` OData types as `ValueType.COMPLEX` instead of
expected `ValueType.GEOSPATIAL`.
Debugging shows that the client uses
[JsonDeserializer|https://github.com/apache/olingo-odata4/blob/master/lib/client-core/src/main/java/org/apache/olingo/client/core/serialization/JsonDeserializer.java#L64]
which does not work correctly with values of `Edm.GeometryCollection` and
`Edm.GeographyCollection` OData types, such as:
{code}
{
"GeometryCollectionField":{
"type":"GeometryCollection",
"geometries":[
{
"type":"Point",
"coordinates":[
1.0,
1.0
],
"crs":{
"type":"name",
"properties":{
"name":"EPSG:4326"
}
}
}
],
"crs":{
"type":"name",
"properties":{
"name":"EPSG:4326"
}
}
}
}
{code}
[I created a unit test to reproduce the
issue|https://github.com/vladglinskiy/olingo-odata4/commit/4613e2a4f266bf99f56dd4cac2d58df0c03efa1d#diff-c2bf3c9859b1f7113d0296bc1b6dcb5dR58]:
{code:java}
@Test
public void toEntityWithGeometryCollectionField() throws Exception {
GeospatialCollection collection = new
GeospatialCollection(Geospatial.Dimension.GEOMETRY, SRID.valueOf("4326"),
Collections.<Geospatial>singletonList(POINT));
ByteArrayOutputStream output = new ByteArrayOutputStream();
OutputStreamWriter writer = new OutputStreamWriter(output, Constants.UTF8);
Entity entity = new Entity();
final Property propertyResource = new Property();
propertyResource.setName("GeometryCollectionField");
propertyResource.setValue(ValueType.GEOSPATIAL, collection);
entity.getProperties().add(propertyResource);
SERIALIZER.write(writer, new ResWrap(null, null, entity));
System.out.println(new String(output.toByteArray()));
ResWrap<Entity> entityResWrap = DESERIALIZER.toEntity(new
ByteArrayInputStream(output.toByteArray()));
Property geometryCollection =
entityResWrap.getPayload().getProperty("GeometryCollectionField");
Assert.assertNotNull(geometryCollection);
ValueType actualValueType = geometryCollection.getValueType();
Assert.assertEquals("Unexpected GeospatialCollection type",
ValueType.GEOSPATIAL, actualValueType);
Assert.assertTrue(geometryCollection.asGeospatial() instanceof
GeospatialCollection);
}
{code}
Please, note that the deserializer works fine with GeometryPoint type.
[toEntityWithPointField
test|https://github.com/vladglinskiy/olingo-odata4/commit/4613e2a4f266bf99f56dd4cac2d58df0c03efa1d#diff-c2bf3c9859b1f7113d0296bc1b6dcb5dR35]
demonstrates that.
*Steps to reproduce:*
1. git clone https://github.com/vladglinskiy/olingo-odata4.git
2. mvn clean test -pl lib/client-core/ -Dtest=JsonDeserializerTest
the test will fail with the following error:
