Spring boot webclient 2gb xml data getting io.netty.handler.timeout.ReadTimeoutException: null

I am calling the api which returns XML response having data around 2gb , i am using Webclient to call xml data using below logic
private InputStream getUserResponse() throws UserClientException {
ClientResponse response = webClient
.get()
.uri(apiBaseURI)
.header(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_XML_VALUE)
.accept(APPLICATION_XML)
.exchange()
.block();
PipedOutputStream po = new PipedOutputStream();
final PipedInputStream pi;
try {
pi = new PipedInputStream(po);
} catch (IOException e) {
throw new UserClientException(e);
}
if (response != null) {
int statusCode = response.rawStatusCode();
if (statusCode != 200) {
throw new UserClientException(new Exception(" Error from the client with statuscode " + statusCode));
}
Flux<DataBuffer> dataBufferFlux = response.body(BodyExtractors.toDataBuffers())
.doOnError(t -> {
try (pi)
{
log.error("Error in reading the data buffer body ", t);
} catch (IOException io) {
log.error("Error closing input stream", io);
}
})
.doFinally(s -> {
try (po) {
log.debug("finally called ");
} catch (IOException io) {
log.error("Error closing output stream", io);
}
});
DataBufferUtils.write(dataBufferFlux, po)
.subscribe(DataBufferUtils.releaseConsumer());
}
return pi;
}
But getting the below error

Still the data is there but it seems webclient is closing the connection, i see its printing 0 active and inactive channel connection

This is due to the readtimeout configured in our code Webclient as 3 second due to that the error was ,increased the readtimeout and it worked.

org.springframework.web.client.HttpClientErrorException$BadRequest: 400 Bad Request

For the below code I am getting a 400 Bad Request
public String saveQuoteCall(String jsonObjectStr) {
try {
preparePostHttpEntity(jsonObjectStr);
response = restTemplate.exchange(CREATE_QUOTE_URL, HttpMethod.POST, entity, String.class);
log.info("Response : " + response.getStatusCode());
if (response.getStatusCode() == HttpStatus.OK) {
return response.getBody();
}
} catch (Exception e) {
log.error("Error in saveQuoteCall : ", e);
}
return "No Data";
}
private void preparePostHttpEntity(String sendingStr) {
try {
headers = new HttpHeaders();
log.info("request in checkCDBalance preparePostHttpEntity: " + sendingStr);
headers.set(HttpHeaders.WWW_AUTHENTICATE, ServiceSecurity.getHeaderValue());
// log.info("request in checkCDBalance preparePostHttpEntity:
// "+HttpHeaders.WWW_AUTHENTICATE);
headers.setAccept(Arrays.asList(new MediaType[] { MediaType.TEXT_PLAIN }));
headers.setContentType(MediaType.TEXT_PLAIN);
entity = new HttpEntity<String>(sendingStr, headers);
log.info("entity value: " + entity);
restTemplate = new RestTemplate();
} catch (Exception e) {
log.error("Error in preparePostHttpEntity : ", e);
}
}
Following is the stacktrace

400 Bad Request response status code indicates that the server cannot or will not process the request due to something that is perceived to be a client error (e.g., malformed request syntax, invalid request message framing, or deceptive request routing)
You got 400 response because of some sort of error in your request.
If you want to know more about it, you can debug the response you receive (represented by ClientHttpResponse object) in DefaultResponseErrorHandler::handleError method. You should be able to detect the problem yourself by looking into body of the response.

How to resolve IllegalArgumentException: Target object must not be null

When I try to save a list of objects to a repository using the saveAll() method, most of the times my code works. However, sometimes I get an "IllegalArgumentException: Target object must not be null" error. The strange thing is that if I call the method again later, or recompile, the same list is successfully saved. My code is below:
The class for the repository:
#Data
#Entity
#Table(name = "stock_history")
public class StockHistory {
#Id
#GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "history_generator")
#SequenceGenerator(name = "history_generator", sequenceName = "history_seq")
#Column(name = "history_id")
private Long id;
private String symbol;
private Float close;
private String date;
}
The service layer to get the data from a provider:
#Override
#Transactional(rollbackFor = Exception.class)
public void fetchAndUpdateStockHistoricalDataOneByOne() {
final int historyLength = 252;
String worldTradingUrl = "https://www.worldtradingdata.com/api/v1/history";
Set<String> listOfSymbols = getInvestorStocks().stream().map(Stock::getSymbol).collect(Collectors.toSet());
List<StockHistory> stockHistory = new ArrayList<>();
for (String stk : listOfSymbols) {
List<StockHistory> eachStock = new ArrayList<>();
RestTemplate restTemplate = new RestTemplate();
UriComponentsBuilder builder = UriComponentsBuilder.fromUriString(worldTradingUrl)
.queryParam("symbol", stk)
.queryParam("api_token", "X")
.queryParam("date_from", "2018-05-01");
try {
String uri = URLDecoder.decode(builder.toUriString(), StandardCharsets.UTF_8);
String result = restTemplate.getForObject(uri, String.class);
JsonParser jsonParser = new JsonParser();
JsonObject jsonObject = (JsonObject) jsonParser.parse(result);
JsonElement jsonElement = jsonObject.get("history");
Set<Map.Entry<String, JsonElement>> entrySet = jsonElement.getAsJsonObject().entrySet();
entrySet.parallelStream().forEach(entry -> {
StockHistory history = new StockHistory();
history.setSymbol(stk);
history.setDate(entry.getKey());

The error refers to an assertion (notNull) issue. What I do not understand is where and why only sometimes happens. Please, any help would be great.

I had a similar issue with .saveAll(list) with following exception.
org.springframework.dao.InvalidDataAccessApiUsageException: Target object must not be null; nested exception is java.lang.IllegalArgumentException: Target object must not be null
at org.springframework.orm.jpa.EntityManagerFactoryUtils.convertJpaAccessExceptionIfPossible(EntityManagerFactoryUtils.java:373)
It was due to a NULL object in the List I was saving. I fixed the issue by adding .filter (s -> s != null) on the List before .saveAll(list).

IllegalArgumentException exception indicates that a method is called with incorrect input arguments. Check with Postman Tool if u are Saving Correct Input Arguments.

I had the same issue, but I figured out, that the parallelstream is causing the problem. I fixed it by replacing it with a simple forEach.

Why does Hibernate saves my entities list several times?

I'm currently working on a Spring-boot application written in Kotlin. I'm writting an API which permits a logged user to add a metro station or a metro line to his favorite (and have informations about it more quickly).
My users are represented by the ApplicationUser class with a username, a password, a set of his favorite metro lines, and another set for his favorite metro stations.
I have written a controller to allow logged in users adding a line or a station to their favorites. I also have written a function which return the current user. This is how my controller looks like:
#RestController
#RequestMapping("/favorites")
class FavoriteController(private val applicationUserRepository: ApplicationUserRepository,
val lineService: LineService,
val stationService: StationService,
private var currentUser: ApplicationUser?) {
private fun provideCurrentUser() : ApplicationUser? {
if(this.currentUser == null) {
val currentUsername: String = SecurityContextHolder.getContext().authentication.principal.toString()
this.currentUser = this.applicationUserRepository.findByUsername(currentUsername)
}
return this.currentUser
}
#PostMapping
fun addFavorite(#RequestParam(value = "type", required = true)type: FavoriteType?,
#RequestParam(value = "id", required = true)id: Long?) : ResponseEntity<String> {
return if(provideCurrentUser() == null || type == null || id == null) {
ResponseEntity.status(HttpStatus.UNPROCESSABLE_ENTITY).body("You have to be logged and provide the type " +
"and the id of the desired entity in order to add it to your favorites list")
} else {
when(type) {
FavoriteType.STATION -> {provideCurrentUser()?.addToFavorites(this.stationService.findById(id) as Station)
this.applicationUserRepository.save(provideCurrentUser() ?: throw Exception("User Not found"))}
FavoriteType.LINE -> {provideCurrentUser()?.addToFavorites(this.lineService.findById(id) as Line)
this.applicationUserRepository.save(provideCurrentUser() ?: throw Exception("User Not found")) }
FavoriteType.UNKNOWN -> return ResponseEntity.status(HttpStatus.UNPROCESSABLE_ENTITY).body("Unknown entity type")
}
ResponseEntity.status(HttpStatus.CREATED).body("The $type with id $id has been successfully added to your favorites")
}
}
I thought it was working but it actually raises an exception after three calls. Both first and second call works fine, but if call this function a third time, an exception is raised due to duplicate primary key in the database. I use JpaRepository functions to manage my entities (save).
i assume this issue could come from an early closing of the transaction, but I don't know how to check if it's right, or how to fix it...
here is the code of my ApplicationUser class if you need it:
#Entity
class ApplicationUser(val username: String = "",
var password: String = "",
#ManyToMany(cascade= [CascadeType.ALL], fetch = FetchType.EAGER)
#JoinTable(name="user_favstation", joinColumns= [JoinColumn(name="user_id")], inverseJoinColumns=[JoinColumn(name="station_id")])
#CollectionId(
columns = [Column(name="COLLECTION_ID")],
type= Type(type="long"),
generator = "sequence"
)
var favoriteStations: MutableList<Station> = mutableListOf(),
#ManyToMany(cascade= [CascadeType.ALL] , fetch = FetchType.EAGER)
#JoinTable(name="user_favline", joinColumns= [JoinColumn(name="user_id")], inverseJoinColumns=[JoinColumn(name="line_id")])
#CollectionId(
columns = [Column(name="COLLECTION_ID")],
type= Type(type="long"),
generator = "sequence"
)
var favoriteLines: MutableList<Line> = mutableListOf())
: BaseEntity() {
fun addToFavorites(station: Station): Boolean {
return this.favoriteStations.add(station)
}
fun addToFavorites(line: Line): Boolean {
return this.favoriteLines.add(line)
}
fun deleteFavorite(station: Station): Boolean {
return this.favoriteStations.remove(station)
}
fun deleteFavorite(line: Line): Boolean {
return this.favoriteLines.remove(line)
}
}
Here is the exception stacktrace:

EDIT: I modified my ApplicationUser class by adding #CollectionId annotation above my two list of favorites. Since this annotation doesn't work with MutableSet, I change them to MutableList. Now my controller doesn't raise any exception BUT I found that every time I try to add a favorite hibernate add EVERY favorites again. After adding only 4 stations to my favorites, my favorite stations table looks like this (and I don't know why) :
I hope someone can help me, thank you in advance.

org.apache.poi.xwpf.converter.core.XWPFConverterException: java.lang.NullPointerException (Java)

I am getting conversion error while converting docx to pdf.
This is my code:
private File convertFileToPdf(MultipartFile file) {
try {
File docFile = new File(file.getOriginalFilename());
String extension =
FilenameUtils.getExtension(file.getOriginalFilename());
File pdfFile = new
File(file.getOriginalFilename().replace(extension, "pdf"));
log.debug(file.getOriginalFilename());
docFile.createNewFile();
InputStream doc = new FileInputStream(docFile);
XWPFDocument document = new XWPFDocument(doc);
PdfOptions options = PdfOptions.create();
OutputStream out = new FileOutputStream(pdfFile);
PdfConverter.getInstance().convert(document, out, options);
return pdfFile;
} catch (Exception e) {
log.error("exception while converting file to pdf", e);
return null;
}
}

This converts some docx file to pdf but sometimes it gives exception while converting to pdf.
I get exception at PdfConverter.getInstance().convert(xwpfDocument, out, options); line.
Please help me with this.
Thanks in advance.

I believe
org.apache.poi.xwpf.converter.core.styles.run.RunUnderlineValueProvider.getValue(RunUnderlineValueProvider.java:40)
this is the cause as converter trying to read style string it might be getting null. If you are manipulating the xwpfdocument you should take care of it programmatically.
