How to POST the following JSON structure using Apache OLINGO client? What is the best way to build up this structure? Are there any examples?
{
"itemNumber": "ITEM1"
"lines": [
{
componentNumber": "COMPONENT1"
},
{
componentNumber": "COMPONENT2"
}
]
}

The following Java example using the Olingo Client works for me to post the following JSON structure:
{
"itemNumber": "ITEM1"
"lines": [
{
componentNumber": "COMPONENT1"
},
{
componentNumber": "COMPONENT2"
}
]
}
Java code using OLINGO CLient
public void deepInsertExample(){
//Initiate the ODATA client
ODataClient client = ODataClientFactory.getClient();
client.getConfiguration();
getClient().getObjectFactory();
//Initiate the Client Object Factory
ClientObjectFactory factory = getClient().getObjectFactory();
//Create Line Item 1
ClientEntity lineItem1 = factory.newEntity(new FullQualifiedName("ODATA.LineItem"));
lineItem1.getProperties()
.add(factory.newPrimitiveProperty("componentNumber", factory.newPrimitiveValueBuilder().buildString("COMPONENT2")));
//Create Line Item 2
ClientEntity lineItem2 = factory.newEntity(new FullQualifiedName("ODATA.LineItem"));
lineItem2.getProperties()
.add(factory.newPrimitiveProperty("componentNumber", factory.newPrimitiveValueBuilder().buildString("COMPONENT1")));
//Initiate the entity set
ClientEntitySet entitySet = factory.newEntitySet();
//Add Line Item 1 and Line Item 2 to the Enity
entitySet.getEntities().add(lineItem1);
entitySet.getEntities().add(lineItem2);
//Create the Lines LInk
ClientLink linesLink = factory.newDeepInsertEntitySet("Lines", entitySet);
ClientComplexValue complexValueCreate = factory.newComplexValue("Lines");
complexValueCreate.getNavigationLinks().add(linesLink);
//Create the Item object
ClientEntity item = factory.newEntity(new FullQualifiedName("ODATA.Item"));
item.getProperties()
.add(factory.newPrimitiveProperty("itemNumber", factory.newPrimitiveValueBuilder().buildString("ITEM1")));
//Add the Lines(Entity Set) link to Item Object
item.addLink(linesLink);
//Post the Item
URI absoluteUri = client.newURIBuilder("URL").build();
ODataEntityCreateRequest<ClientEntity> request = client.getCUDRequestFactory()
.getEntityCreateRequest(absoluteUri, item);
request.setAccept("application/json;odata.metadata=minimal");
request.execute();
}

You will have to specify the the NavigationPropertyName
in the deep part. So for your sample payload it would look like
{
"itemNumber": "ITEM1",
"lines": {
"componentNumber":"COMPONENT1",
"componentNumber":"COMPONENT2",
}
}
You can refer to this post in SO to get details about n level nesting
The above answer asuumes that your NavigationProperty is named lines
, you can substitute it with the right name by looking at service/$metadata
The answer assumes that you are trying to do deep inserts in a odata2 service, for OData4 the concept remains the same but syntax might vary a bit. Please refer to the payload descripted in documentation in case of OData 4
