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

I want to re_index only selected fields from my document in elasticsearch using Rest High level client.
I know the elasticsearch query to achieve that but I don't know it's equivalent query using rest client.
Following is the elasticsearch query which I am trying to implement using rest client -
{
"body" : {
"source" : {
"index" : "my source index name",
"_source" : "id, name, rollNo"
},
"dest" : {
"index" : "my destination index name"
}
}
}
To write its equivalent query using rest client in java, I have used the following code -
ReindexRequest reindexRequest = new ReindexRequest();
reindexRequest.setSourceIndices("source index name").setDestIndex("destination index name");
reindexRequest.setDocTypes("id", "name", "rollNo", "_doc");
client.reindex(reindexRequest,RequestOptions.DEFAULT);
But the above code is not working as expected. It's re_indexing all the fields of my document. I want only selective 3 fields to be re_indexed from each doc.
You need to use below code as setDocTypes is not used for source filtering.
As there is no direct method available for setting source filter so you need to change underlying search request suing below code.
ReindexRequest reindexRequest = new ReindexRequest();
reindexRequest.setSourceIndices("source index name").setDestIndex("destination index name");
reindexRequest.setDocTypes("_doc");
String[] include=new String[] {"id", "name", "rollNo"};
String[] exclude=new String[] {"test"};
reindexRequest.getSearchRequest().source().fetchSource(include, exclude);
client.reindex(reindexRequest,RequestOptions.DEFAULT);
I have a requirement to build a JSON dynamically and need to call an external API.
For instance,
Input : "FIRST_NAME": "XXX"
Based on the above input I need to build a JSON dynamically like below
{
"Req":{
"user":{
"CreatedTime":"2017-03-02T07:52:58Z",
"UpdatedTime":"2017-03-02T07:52:58Z",
"Details":{
"Names":[
{
"Name":{
"First":"kirtq"
}
}
]
}
}
}
}
If I get contact number as input : CONTACT_NUMBER:889999999
Then I have to build a JSON like below
{
"UpdateMemberReq": {
"Customer": {
"CreatedTime": "2017-03-02T07:52:58Z",
"UpdatedTime": "2017-03-02T07:52:58Z",
"CustomerDetails": {
"Contacts": {
"MobilePhone": {
"value": "07888728687"
}
}
}
}
}
}
Like this I have around 30 fields for each request I will get one filed based on that I have to build a JSON dynamically and once I prepared the JSON dynamically I have to call an external API (POST) by passing this JSON as raw type in the body.
I have implemented like below .
List list = new ArrayList();
Name user = mapper.readValue(json2, Name.class);
System.out.println(user);
Map<String, Object> name1 = new HashMap<>();
name1.put("Name", user);
list.add(name1);
Map<String, Object> map1 = new HashMap<>();
map1.put("Names", list);
Map<String, Object> map2 = new HashMap<>();
map2.put("CustomerDetails",map1);
Map<String,Object> map = new HashMap();
map.put("Customer",map2);
Can anyone suggest to me the best way to handle this in java/spring boot?
Thanks!!
Can anyone suggest to me the best way to handle this in java/spring boot?
Given that you don't have a fixed schema for which you want to create JSON, you'll have to do exactly like you do.
This means assembling a map dynamically and then mapping it to a json string.
What you can do to improve is try to extract common and reusable components, for building certain parts of the request.
I'd recommend you create a class structure to keep things manageable with some classes like ...
JsonGenerationService ( the main service the rest of the code uses )
UserJsonGenerator -> generates JSON for user entities
CustomerJsonGenerator -> generates JSON for customers
JsonGeneratorCommon -> contains all the common methods
I am working with ms graph and i need to integrate with ms teams. In one case i have to send a message to a channel which will contain a channel mention (#). Currently i have found how to tag a specific user using java but i cant figure out how to mention the whole channel. It is posible to do so in ms graph and if yes how?
To be more specific here is an example. Assume that i have a team named TestTeam and this team has a channel named testChannel. i need to send a message where will contain #testChannel and will send a notification to everyone in this channel.
Also in slack api i am able to do this action by using "<!channel>" in my message.
This is the code i am using in order to tag a user:
static void send_message(String text, String mentionName, String channelName, String teamName, String accessToken) {
ensureGraphClient(accessToken);
Team team = getTeam(accessToken, teamName);
Channel channel = getChannel(accessToken, channelName, team);
User user = getUser(accessToken, mentionName);
if (userInChannel(user, team, channel)) {
ChatMessage chatMessage = new ChatMessage();
ItemBody body = new ItemBody();
body.contentType = BodyType.HTML;
body.content = String.format("%s. <at id=\"1\">%s</at> ", text, mentionName);
chatMessage.body = body;
ChatMessageMention m = new ChatMessageMention();
m.id = 1;
IdentitySet st = new IdentitySet();
Identity ide = new Identity();
ide.id = user.id;
ide.displayName = user.displayName;
st.user = ide;
m.mentioned = st;
m.mentionText = mentionName;
List<ChatMessageMention> cmmt = new LinkedList<>();
cmmt.add(m);
chatMessage.mentions = cmmt;
graphClient.teams(team.id).channels(channel.id).messages()
.buildRequest()
.post(chatMessage);
}
}
I also tried something similar in order to tag channels but it did not worked:
body.contentType = BodyType.HTML;
body.content = String.format("%s. <at id=\"1\">%s</at> ", text, "myChannel");
chatMessage.body = body;
ChatMessageMention m = new ChatMessageMention();
m.id = 1;
IdentitySet st = new IdentitySet();
Identity ide = new Identity();
ide.id = "19%xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx%40thread.tacv2";
ide.displayName = "myChannel";
st.user = ide;
m.mentioned = st;
m.mentionText = "myChannel";
List<ChatMessageMention> cmmt = new LinkedList<>();
cmmt.add(m);
chatMessage.mentions = cmmt;
graphClient.teams(team.id).channels(channel.id).messages()
.buildRequest()
.post(chatMessage);
Introduction:
After playing around with it, here is the final result. And this is not final answer, but hope to lead for solution.
Lets start some introduction.
First lets define our post url:
POST https://graph.microsoft.com/beta/teams/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/channels/19:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx#thread.tacv2/messages
Now lets mentioning a user in graph api:
{
"body": {
"contentType": "html",
"content": "Hello World <at id=\"0\">Maytham Fahmi</at>"
},
"mentions": [
{
"id": 0, <- the index here should be the same as in the content message
"mentionText": "Maytham Fahmi",
"mentioned": {
"user": {
"displayName": "Maytham Fahmi",
"id": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" <- this should be user user object id
}
}
}
]
}
This is tested and working via Graph Api.
Now I come to the interested part. Sending to channel with channel mentioning looks like this:
{
"body": {
"contentType": "html",
"content": "Hello World <at id=\"0\">General</at>"
},
"mentions": [
{
"id": 0, <- the index here should be the same as in the content message
"mentionText": "General",
"mentioned": {
"conversation": {
"id": "19:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx#thread.tacv2",
"displayName": "General",
"conversationIdentityType#odata.type": "#Microsoft.Teams.GraphSvc.conversationIdentityType",
"conversationIdentityType": "channel"
}
}
]
}
The results in teams, that is sent from channel mentioning
This is also working from Graph api explorer.
The answer:
So as we can see for user mentioning we use User object under IdentitySet instance which works fine for user. I have testing it C# using Microsoft.Graph.
Here is comes the problem Conversation object does not exist under IdentitySet in C# using Microsoft.Graph. I am pretty sure this is the case for Java as well. If you have that object in Java then you should be able to make it. It is perhaps not in C#.
I have red different places, and sadly channel mentioning objects is not implemented in code yet, looks like a bug or a feature they will fix over time.
A work around solution is, you have graph api json payloads, you can make a Java client to post Jsons to the url with and your job is done.
Note: I have look at our solution, it does not support mentioning as well.

Note in case you need to send notification in general, you could use webhooks.
This is my C# webservice which generates a JSON String. The below code block is what im using for that.
List<Dictionary<String, Object>> lstdict = new List<Dictionary<String, Object>>();
...
...
...
Logic for connecting db and getting records in msqldat (data reader)
goes here.
...
...
while (msqldat.Read())
{
var detls = new Dictionary<string, object>();
for (int i = 0; i < msqldat.FieldCount; i++)
{
detls.Add(msqldat.GetName(i), msqldat.IsDBNull(i) ? null :
msqldat.GetValue(i));
lstdict.Add(detls);
}
}
JavaScriptSerializer jss = new JavaScriptSerializer();
String mret = jss.Serialize(lstdict);
The above webservice is called in a java code from android studio and it returns the below String.
{"GetDataResult":"[
{\"uname\":\"hkIUZIikXVTC5aNaSva8IQ==\",
\"passwd\":\"hkIUZIikXVTC5aNaSva8IQ==\",
\"validupto\":\"\\\/Date(1545330600000)\\\/\",
\"dept\":\"juubHSHgLr\/3JWnrZCh5LeeW5Q7lioWOZ1\/Tg+YRy\/o=\",
\"rid\":1},
{\"uname\":\"hkIUZIikXVTC5aNaSva8IQ==\",
\"passwd\":\"hkIUZIikXVTC5aNaSva8IQ==\",
\"validupto\":\"\\\/Date(1545330600000)\\\/\",
\"dept\":\"juubHSHgLr\/3JWnrZCh5LeeW5Q7lioWOZ1\/Tg+YRy\/o=\",
\"rid\":2}]"}
I am trying to get the values in android application by using this Java code :
JSONObject uiobj = new JSONObject(mret);
JSONArray arrUserinfo = uiobj.getJSONArray("GetDataResult");
arrUserinfo.getJSONObject(0).getString("uname"))
The code fails at the second line. I'm new to JSON. Not sure if the JSON generated from c# code is not right or java code for parsing is not right. Please advise further. Thank you in advance.
The above json is serialized you need to parse json and then extract the object from it.
See this json valid..
{
"GetDataResult": [{
"uname": "hkIUZIikXVTC5aNaSva8IQ==",
"passwd": "hkIUZIikXVTC5aNaSva8IQ==",
"validupto": "/Date(1545330600000)/",
"dept": "juubHSHgLr/3JWnrZCh5LeeW5Q7lioWOZ1/Tg+YRy/o=",
"rid": 1
},
{
"uname": "hkIUZIikXVTC5aNaSva8IQ==",
"passwd": "hkIUZIikXVTC5aNaSva8IQ==",
"validupto": "/Date(1545330600000)/",
"dept": "juubHSHgLr/3JWnrZCh5LeeW5Q7lioWOZ1/Tg+YRy/o=",
"rid": 2
}
]
}
To parse json in java see below post..

We use Google Sheet API v4. We want to clear entire sheet with empty data. We don't want to delete rows/columns.
Not working UpdateCells Call(Delete Columns by API) :
developers.google.com
Working UpdateCells Call(All Cells) :
developers.google.com
I was able to do it by using the clear method documented here looking at rev607.
ClearValuesRequest clearValuesRequest = new ClearValuesRequest();
// assumes you have a sheetservice initialized
sheetsService.spreadsheets().values().clear(spreadsheetId, "Sheet1", clearValuesRequest);
The key insight that wasn't well documented is you can pass in just the sheet name for the range and that clears ALL cells in the sheet.
Here's the Java Quickstart for Spreadsheet API.
You will then be using spreadsheets.batchUpdate to clear the sheets.Leave fields blank and place an asterisk to instruct Sheets API that all cells should be empty/cleared.
The following body request looks like:
{
"requests": [
{
"updateCells": {
"range": {
"sheetId": 0
},
"fields": "*"
}
}
]
}
Give this a quick-try in the oauth playground.
UPDATE: This is working now. It cleared my spreadsheet.
I don't know if this will help anyone else, but this is how I got it working for me:
This should clear your entire sheet.
I do not recall why 'sheetId' is 0, but perhaps it is an index into the sheets within the sheet itself. (like how you have tabs?)
I honestly do not remember though.
The function expects you to pass in your $service object and the spreadsheetID.
function clearSheet($service, $spreadsheetID = 0){
$request = new \Google_Service_Sheets_UpdateCellsRequest([
'updateCells' => [
'range' => [
'sheetId' => 0
],
'fields' => "*" //clears everything
]
]);
$requests[] = $request;
$requestBody = new Google_Service_Sheets_BatchUpdateSpreadsheetRequest();
$requestBody->setRequests($requests);
$response = $service->spreadsheets->batchUpdate($spreadsheetID, $requestBody);
return $response;
}
Java example:
UpdateCellsRequest clearAllDataRequest = new UpdateCellsRequest();
int allSheetsId = 0;
String clearAllFieldsSpell = "*";
GridRange gridRange = new GridRange();
gridRange.setSheetId(allSheetsId);
clearAllDataRequest.setRange(gridRange);
clearAllDataRequest.setFields(clearAllFieldsSpell);
BatchUpdateSpreadsheetRequest request = new BatchUpdateSpreadsheetRequest();
Request clearAllDataRequest = new Request().setUpdateCells(clearAllDataRequest);
request.setRequests(List.of(clearAllDataRequest));
return request;
