Why aren't my transactions rendering? --React & Java

Why aren't my transactions rendering? --React & Java - java

I can't seem to figure out where I'm going wrong in my code to cause my app to not completely render the transactions. I double-checked my variables in both mySQL & in React, so it's not a variable issue. I'm not sure if the error lies on the front-end (React) side, but I'm fairly sure that it does.
Here is my code for TransactionsList:
function TransactionsList() {
const [transactions, setTransactions] = useState([]);
useEffect(() => {
let username = AuthenticationService.getLoggedInUserName();
TransactionDataService.retrieveAllTransactions(
username
).then((transactions) => setTransactions([transactions]));
}, []);
return (
<CardColumns style={{ padding: "20px" }}>
{transactions.map((transaction) => (
<TransactionCard transaction={transaction} />
))}
</CardColumns>
);
}
Here is my code for TransactionCard:
const username = AuthenticationService.getLoggedInUserName();
TransactionDataService.retrieveTransaction(username, useState.id).then(
(response) =>
useState({
accountName: response.data.accountName,
transactionDate: response.data.transactionDate,
transactionType: response.data.transactionType,
depositCategory: response.data.depositCategory,
withdrawalCategory: response.data.withdrawalCategory,
transactionAmount: response.data.transactionAmount,
notes: response.data.notes,
})
);
export default function TransactionCard(props) {
const classes = useStyles();
const [expanded, setExpanded] = useState(false);
const handleExpandClick = () => {
setExpanded(!expanded);
};
const { transaction } = props;
// const { data: transactions } = useSWR((url) =>
// fetch(url).then((_) => _.json())
// );
const getTransactions = (url) => fetch(url).then((_) => _.json());
const { data: transactions } = useSWR(
`http://localhost:8080/jpa/users/${username}/transactions`,
getTransactions
);
useEffect(() => {
console.log(transactions);
}, [transactions]);
function handleEdit(id) {
console.log("handle edit");
alert("you clicked edit");
}
function handleDelete(id) {
console.log("handle delete");
}
return (
<>
<Card className={classes.card}>
<center>
<CardHeader tag="h3">{transaction.accountName}</CardHeader>
<CardText>{transaction.transactionType}</CardText>
<CardText>
{moment.utc(transaction.transactionDate).format("MMM-DD-YYYY")}
</CardText>
<CardText>{transaction.depositCategory}</CardText>
<CardText>{transaction.withdrawalCategory}</CardText>
<CardText>{"$" + parseFloat(transaction.transactionAmount)}</CardText>
</center>
Here is the relevant Java code:
#GetMapping("/jpa/users/{username}/transactions")
public List<Transaction> getAllTransactions(#PathVariable String username) {
return transactionJpaRepository.findByUsername(username);
}
Here are my findings from when I did a curl:

return false;
return true;

}
Debugging reveals this once I stepped over transactionJpaRepository.findByUsername(username):
"Hibernate: select transactio0_.id as id1_1_, transactio0_.account_name as account_2_1_, transactio0_.deposit_category as deposit_3_1_, transactio0_.notes as notes4_1_, transactio0_.transaction_amount as transact5_1_, transactio0_.transaction_date as transact6_1_, transactio0_.transaction_type as transact7_1_, transactio0_.username as username8_1_, transactio0_.withdrawal_category as withdraw9_1_ from transaction transactio0_ where transactio0_.username=?"

It's a lot of code to follow, but one thing stands out at me when I glance over this code...
You set your state-managed transactions up to be an array of transaction as such:
const [transactions, setTransactions] = useState([]);
Then you clearly have a local object coming back from your TDS promise called "transactions" which I'm guessing would ALSO be an array.
TransactionDataService.retrieveAllTransactions(username)
.then((transactions) => setTransactions([transactions]));
So if that's all true, then your state-driven setTransactions call here is taking your Promise-Returned array and wrapping it into a single-array element...
So your state-driven transactions after this would look like:
transactions = [
[ tx1, tx2, tx3, .... ]
]
In this case, it makes sense that your state-driven transactions object only has one record in it. Although that one-record should be the array of all transactions..
If this is the case, the solution is to fix your setTransactions to NOT have a [] wrapping your promise-returned transactions array.
That said, reading the comments it does sound like curl/back-end needs addressing before you hit this.

How to get row from TableView?

I am creating a lobby application which will show all groups on a java tableview. Users are able to join groups that have space in them, else they will not be able to join.
I have been able to create this but I would like to be able to colour the row of the groups that have space in them in green and groups that are full will be coloured in red.
I will provide my code for this below. I am getting NullPointerException, which i dont know why. Thanks.
private void visualGroupAvailability() {
boolean isThereSpace;
for (currentGroupsModel o : groupsTable.getItems()) {
TableRow<currentGroupsModel> currentRow = getTableRow(o.getGroupID());
int limit = o.getNumberOfUsers();
isThereSpace = checkSpaceInGroup(o);
if(isThereSpace) {
currentRow.setStyle("-fx-background-color: #" + "388e3c ");
} else {
currentRow.setStyle("-fx-background-color: #" + "ffcdd2 ");
}
}
}
private TableRow<currentGroupsModel> getTableRow(int rowIndex) {
Set<Node> tableRowCell = groupsTable.lookupAll(".table-row-cell");
TableRow<currentGroupsModel> row = null;
for (Node tableRow : tableRowCell) {
TableRow<currentGroupsModel> r = (TableRow<currentGroupsModel>) tableRow;
row = r;
}
return row;
}
public class currentGroupsModel {
String groupName, groupDescription, hostName, groupType;
Integer numberOfUsers, groupID;
public currentGroupsModel(String gName, String gDesc, String hostName, String groupType, Integer numberOfUsers, Integer groupID){
this.groupName = gName;
this.groupDescription = gDesc;
this.hostName = hostName;
this.groupType = groupType;
this.numberOfUsers = numberOfUsers;
this.groupID = groupID;
}
public String getGroupName() {
return groupName;
}
public void setGroupName(String groupName) {
this.groupName = groupName;
}
public String getGroupDescription() {
return groupDescription;
}
public void setGroupDescription(String groupDescription) {
this.groupDescription = groupDescription;
}
public String getHostName() {
return hostName;
}
public void setHostName(String hostName) {
this.hostName = hostName;
}
public String getGroupType() {
return groupType;
}
public void setGroupType(String groupType) {
this.groupType = groupType;
}
public Integer getNumberOfUsers() {
return numberOfUsers;
}
public void setNumberOfUsers(int numberOfUsers) {
this.numberOfUsers = numberOfUsers;
}
public Integer getGroupID(){
return this.groupID;
}
public void setGroupID(Integer newID){
this.groupID = newID;
}
}

This question cannot really be answered with what you have given us. It is hard looking for a NullPointerException if there is a currentGroupModel we know nothing about and there are constant red hairings. For example why do you store something in limit, you never use it! Why do you pass getTableRow a rowIndex, that you are never using? As far as I get it your getTableRow returns the last TableRow in the table, not a specific one. Please consider fixing those problems first, before eventually providing some code to understand the inner workings of your currentGroupModel.

response.body().getBasketShopList is empty, but API JSON in Postman is not empty

I am new to Android, it's about a week that I am spending 3 hours a day on this problem but still I can not find a solution, I am going to get a list of object from server and pass them to Adapter and another process. But I got into trouble, there is no error, in my Android Studio I got " response.code = 200 " but a list of my object is empty although in Postman with same authorization and same username a list of object is not empty. I don't know what should I do, so finally I forced to ask my question hear.
First let's take a look on Postman
Body : :
Authorization : :
Now when I clicked on Send Button in Postman I got "code: 200" and hear is the response Body:
{
"results": [
{
"_id": "5c7e69d283c0b00001108fad",
"count": 2,
"productId": "5ba51d877246b700016ec205",

"ACL": {
"*": {
"read": true,
"write": true
}
}
},

"count": 4,
"productId": "5acc0f2c790c0c000132c984",

"ACL": {

"read": true,
"write": true
}
}
}
]
}
In my OnlineShopAPI Interface:
public interface OnlineShopAPI {
String BASE_URL = "https://api.backtory.com/";
#Headers("X-Backtory-Object-Storage-Id:5a154d2fe4b03ffa0436a535")
#HTTP(method = "POST" , path = "object-storage/classes/query/Basket" , hasBody = true)
Call<MainBasketShopResponse> mainBasketShop (
#Header("Authorization") String authorization,
#Body BasketShop basketShop
);
interface getMainBasketShop {
void onResponse(List<BasketShop> basketShopList);
void onFailure(String cause);
}
}
My MainBasketShopResponse class:
public class MainBasketShopResponse {
#SerializedName("results")
List<BasketShop> basketShopList;
public MainBasketShopResponse() {
}
public List<BasketShop> getBasketShopList() {
return basketShopList;
}
public void setBasketShopList(List<BasketShop> basketShopList) {
this.basketShopList = basketShopList;
}
}
BasketShop class:
public class BasketShop {
#SerializedName("username")
private String username;
#SerializedName("productId")
private String productId;
#SerializedName("count")
private float count;
#SerializedName("createdAt")
private String createdAt;
#SerializedName("_id")
private String id;
public String getCreatedAt() {
return createdAt;
}
public void setCreatedAt(String createdAt) {
this.createdAt = createdAt;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public BasketShop(String username) {
this.username = username;
}
public BasketShop() {
}
public BasketShop(String username, String productId, float count) {
this.username = username;
this.productId = productId;
this.count = count;
}
public BasketShop(String createdAt, String id) {
this.createdAt = createdAt;
this.id = id;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getProductId() {
return productId;
}
public void setProductId(String productId) {
this.productId = productId;
}
public float getCount() {
return count;
}
public void setCount(float count) {
this.count = count;
}
}
My Controller that contain retrofit:
public class MainBasketShopController {
OnlineShopAPI.getMainBasketShop getMainBasketShop;
public MainBasketShopController(OnlineShopAPI.getMainBasketShop getMainBasketShop) {
this.getMainBasketShop = getMainBasketShop;
}
public void start(String authorization , BasketShop basketShop){
Retrofit retrofit = new Retrofit.Builder()
.addConverterFactory(GsonConverterFactory.create())
.baseUrl(OnlineShopAPI.BASE_URL)
.build();
OnlineShopAPI onlineShopAPI = retrofit.create(OnlineShopAPI.class);
Call<MainBasketShopResponse> call = onlineShopAPI.mainBasketShop(authorization , basketShop);
call.enqueue(new Callback<MainBasketShopResponse>() {
#Override
public void onResponse(Call<MainBasketShopResponse> call, Response<MainBasketShopResponse> response) {
if (response.isSuccessful()) {
Log.d("emptyhst1" , response.body().getBasketShopList().toString());
Log.d("emptyhst2" , Integer.toString(response.body().getBasketShopList().size()));
getMainBasketShop.onResponse(response.body().getBasketShopList());
}
}
#Override
public void onFailure(Call<MainBasketShopResponse> call, Throwable t) {
getMainBasketShop.onFailure(t.getMessage());
}
});
}
}
Hear is a part of my BasketShopFragment that I call MainBasketShopController with it:
MainBasketShopController mainBasketShopController = new MainBasketShopController(getMainBasketShop);
BasketShop basketShop = new BasketShop();
basketShop.setUsername(MyPreferenceManager.getInstance(getContext()).getUsername());
mainBasketShopController.start(
"bearer " + MyPreferenceManager.getInstance(getContext()).getAccessToken() ,
basketShop
);
OnlineShopAPI.getMainBasketShop getMainBasketShop = new OnlineShopAPI.getMainBasketShop() {
#Override
public void onResponse(List<BasketShop> basketShopList) {
Log.d("emptyhst3" , basketShopList.toString());
basketShopList2.clear();
basketShopList2.addAll(basketShopList);
mainBasketShopAdapter.notifyDataSetChanged();
}
#Override
public void onFailure(String cause) {
Toast.makeText(getContext(), cause , Toast.LENGTH_SHORT).show();
}
};
I checked both of username and accessToken that i passed to the controller and I am sure that everything is looking like in Postman

After a week I found a solution , I just changed a variable "float count" to "String count" from my Model(BasketShop Class) Ops!
#SerializedName("count")
private String count;

Read json list in java

Previously I was reading json data in the following format:
JSON
{
"CreationTime":"2018-01-12T12:32:31",
"Id":"08f81fd7-21f1-48ba-a991-08d559b88cc5",
"Operation":"AddedToGroup",
"RecordType":14,
"UserType":0,
"Version":1,
"Workload":"OneDrive",
"ClientIP":"115.186.129.229",
"UserId":"omaji7#emumbaa10.onmicrosoft.com",
"EventSource":"SharePoint",
"ItemType":"Web"
}
I am reading this json data from a kafka topic and doing some stream processing on it and passing it onto another topic. In processing I have created two json objects, send and received.
Using this code:
final StreamsBuilder builder = new StreamsBuilder();
KStream<String, String> source_o365_user_activity = builder.stream("o365_user_activity");
source_o365_user_activity.flatMapValues(new ValueMapper<String, Iterable<String>>() {
#Override
public Iterable<String> apply(String value) {
System.out.println("========> o365_user_activity_by_date Log: " + value);
ArrayList<String> keywords = new ArrayList<String>();
try {
JSONObject send = new JSONObject();
JSONObject received = new JSONObject(value);
send.put("current_date", getCurrentDate().toString()); // UTC TIME
send.put("activity_time", received.get("CreationTime")); // CONSTANTS FINAL STATIC(Topic Names, Cassandra keys)
send.put("user_id", received.get("UserId"));
send.put("operation_type", received.get("Operation"));
send.put("app_name", received.get("Workload"));
keywords.add(send.toString());
// apply regex to value and for each match add it to keywords
} catch (Exception e) {
// TODO: handle exception
System.err.println("Unable to convert to json");
e.printStackTrace();
}
return keywords;
}
}).to("o365_user_activity_by_date");
This was fairly simple. Now I have a json data with lists in them.
JSON

How can I go about doing the same thing in my Stream processing?
I want to be able to read JSON data against some keys (including the list data keys).

Why not convert JSON to Object and then filter against using the field in Object?

Can't you do like this?
send.put("target_0_id", received.get("Target").getJSONObject(0).get("ID"));

You can use gson library and can convert the json to object and using getter and setter you can build your desired output JSON. You can also parse the input JSON to fetch the JSONArray details. Following is the code how you can do it using POJO.

How to do paging on Object that isn't Entity?

I'm trying to do paging, very similar to the option of #RepositoryRestResource
but only on object that isn't Entity.
the code:
public class FloorplanDevice {
private String FloorplanName;
private Long FloorplanId;
private Long DeviceId;
private String DeviceName;
private String macAddress;
private Long groupId;
private LocatableType deviceType;
public String getFloorplanName() {
return FloorplanName;
}
public void setFloorplanName(String floorplanName) {
FloorplanName = floorplanName;
}
public Long getFloorplanId() {
return FloorplanId;
}
public void setFloorplanId(Long floorplanId) {
FloorplanId = floorplanId;
}
public Long getDeviceId() {
return DeviceId;
}
public void setDeviceId(Long deviceId) {
DeviceId = deviceId;
}
public String getDeviceName() {
return DeviceName;
}
public void setDeviceName(String deviceName) {
DeviceName = deviceName;
}
public String getMacAddress() {
return macAddress;
}
public void setMacAddress(String macAddress) {
this.macAddress = macAddress;
}
public Long getGroupId() {
return groupId;
}
public void setGroupId(Long groupId) {
this.groupId = groupId;
}
public LocatableType getDeviceType() {
return deviceType;
}
public void setDeviceType(LocatableType deviceType) {
this.deviceType = deviceType;
}
public FloorplanDevice() {
}
public FloorplanDevice(String floorplanName, Long floorplanId, Long deviceId, String deviceName, String macAddress, Long groupId, LocatableType deviceType) {
FloorplanName = floorplanName;
FloorplanId = floorplanId;
DeviceId = deviceId;
DeviceName = deviceName;
this.macAddress = macAddress;
this.groupId = groupId;
this.deviceType = deviceType;
}
}
This object doesn't have Repository but it has controller:
#RequestMapping(
path = arrayOf("/floorplanDevice/{groupId}", "/floorplanDevice/{groupId}/"),
method = arrayOf(RequestMethod.GET))
open fun getFloorplanDevice(#PathVariable("groupId") groupId: Long): ResponseEntity<*>{
var floorplanDevice= floorplanService.getFloorplanDevice(groupId)
return ResponseEntity(floorplanDevice, HttpStatus.OK)
}
So how can I do Paging to this object with page number and size (if it possible sorting also)?
I'm using java Spring
Thank you

Try something like this:
public Page<FloorplanDevice> getFloorplanDevice(#PathVariable("groupId") Long groupId,
#PageableDefault Pageable pageable)
List<FloorplanDevice> list = floorplanService.getFloorplanDevice(groupId);
MutableSortDefinition sort = pageable.getSort() != null ?
StreamSupport.stream(pageable.getSort().spliterator(), false)
.findFirst()
.map(it -> new MutableSortDefinition(it.getProperty(), it.isIgnoreCase(), it.isAscending()))
.orElse(null)
: null;
PagedListHolder<FloorplanDevice> pageHolder = new PagedListHolder<>(list, sort);
pageHolder.setPage(pageable.getPageNumber());
pageHolder.setPageSize(pageable.getPageSize());
pageHolder.resort();
List<FloorplanDevice> content = pageHolder.getPageList();
Page<FloorplanDevice> page = new PageImpl<>(content, pageable, list.size());
return page;
}

Solution:
This is my solution by using PageListHolder.
#RequestMapping(
path = arrayOf("/floorplanDevice/{groupId}/page/{pageNum}/size/{sizeNum}", "/floorplanDevice/{groupId}/page/{pageNum}/size/{sizeNum}/"),
method = arrayOf(RequestMethod.GET))
open fun getFloorplanDevicePage(#PathVariable("groupId") groupId: Long, #PathVariable("pageNum") pageNum: Int,#PathVariable("sizeNum") sizeNum: Int): ResponseEntity<*>{
var floorplanDevice= floorplanService.getFloorplanDevice(groupId)
var paging= PagedListHolder<FloorplanDevice>(floorplanDevice)
var setsize= paging.setPageSize(sizeNum)
if(paging.pageCount>pageNum){
var setpage=paging.setPage(pageNum)}
else{
return throw RuntimeException("page: $pageNum is too big, insert smaller page from 0 to ${paging.pageCount-1}")
}
var pageList= paging.pageList
return ResponseEntity(pageList, HttpStatus.OK)
}

Stax API XML parsing produces null results

I have been trying to get this over for a while now with little or no success. Right now, I am really out of options. I will appreciate some assistance or pointers towards the right direction.... since I believe I am not doing somethings very well.
After parsing with the code below, I have null values in most of the fields: Result{id=30c26c8a-8bdf-4d4d-8f8d-a19661f16877, name=Andriod_Office_Task, owner =generated.Owner#53d8d10a, comment=, creationTime=2016-09-09T19:30, modificationTime=2016-09-09T19:30:05+02:00, reportId=null, taskid=null, host=null, port=null, nvt=null, scanNVTVersion=null, threat=null, severity=null, description=null}

String elementName = parser.getLocalName();
if (elementName.equals("result"))
results.add(readResult(parser));
break;
case XMLStreamReader.END_ELEMENT:
return results;
}
}
throw new XMLStreamException("Premature end of file");
}
public Result readResult(XMLStreamReader parser) throws XMLStreamException, DatatypeConfigurationException {
Result result = new Result();
result.setId(parser.getAttributeValue(null, "id"));
Report report = new Report();

while (parser.hasNext()) {

After some research and attempts with some common xml parsing approaches, I ended up using jackson-dataformat-xml approach. While this might not be the best it gave me what I wanted with much less code. Basically, I had to adapt the annotations in the model classes as below :
#JsonIgnoreProperties(ignoreUnknown=true)
#JacksonXmlRootElement(localName = "results")
public class Results {
#JacksonXmlProperty(localName = "result")
#JacksonXmlElementWrapper(useWrapping = false)
public Result [] result;
public Results() {
}
public Result[] getResult() {
return result;
}
public void setResult(Result[] result) {
this.result = result;
}
#Override
public String toString() {
return "Results [result=" + Arrays.toString(result) + "]";
}
And some adaptations for the parsing class:
public class GetReportsResponseHandler extends DefaultHandler<GetReportsResponse> {
private XmlMapper mapper = new XmlMapper();
public GetReportsResponseHandler() {
super(new GetReportsResponse(), "get_reports_response");
AnnotationIntrospector primary = new JacksonAnnotationIntrospector();
AnnotationIntrospector secondary = new JaxbAnnotationIntrospector();
AnnotationIntrospector pair = new AnnotationIntrospectorPair(primary, secondary);
mapper.setAnnotationIntrospector(pair);
}
#Override
protected void parseStartElement(XMLStreamReader parser) throws XMLStreamException, IOException {
if ("report".equals(parser.getName().toString())){
Report report = mapper.readValue(parser, Report.class);
response.addReport(report);
}
