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.

MongoDB projection on an #Aggregation spring data

I've been struggling with this for some days now. We've just started working with mongoDB and therefore my knowledge of it is extremely limited.
Anyhow here's what I want to do: we have a class called Loan like this:
#Document(collection = "Loans")
public class Loan{
#Id
private String id;
private String type;
private LoanApplication loanApplication;
private LoanDecision loanDecision;
private String loanAppId;
private String loanDecisionId;
private LocalDateTime receivedDate;
private LocalDate leadExpiry;
private Integer previousStatus;
private Integer status;
private Boolean isEligibleForRemove;
private String timeStamp;
private List<String> loanDecisions;
private String activeLoanDecision;
private String lenderReferenceNumber;
private String pdfName;
Because we have to perform various operations when querying this collection we therefor created an aggregation (the aggregation works for we created in Mongo Compass and then exported it into our code) in the LoanRepository:
#Repository
#EnableMongoRepositories
public interface LoanRepository extends MongoRepository<Loan, String> {
#Aggregation(pipeline = {"{$match: {\r\n" +
" 'status':{$in: ?0},\r\n" +
" 'loanApplication.mortgage.requested.lenderSubmission.lenderProfile.lenderCode': ?1\r\n" +
" }},{\r\n" +
" $project: {\r\n" +
" 'applicationId': '$loanApplication.deal.applicationId',\r\n" +
" 'cominedLtv': '$loanApplication.deal.combinedLtv',\r\n" +
" 'receivedDate': '$receivedDate',\r\n" +
//other fields to project
" }\r\n" +
" }\r\n" +
"}, {\r\n" +
" $unwind: {\r\n" +
" path: '$applicants'\r\n" +
" }\r\n" +
"}, {\r\n" +
" $match: {\r\n" +
" 'applicants.primaryApplicantFlag': 'Y'\r\n" +
" }\r\n" +
"}
//other aggregate methods
"})
public List<LoanProjection> findLeads(final List<Integer> leadsStatus, final String lenderCode);
}
The ideea is that after all the above operations we need to return just some fields from the whole Loans table (as can be seen in the $project step). I know that the return type of all the methods from this repository must be Loan and one solution would be to utilise spring projection. Thus i created the necessary projection interfaces (bellow you will find only the interfaces for the fields in the $project step):
public interface LoanProjection {
DealType getDealType();
LocalDate getReceivedDate();
}
public interface DealTypeProjection {
String getApplicationId();
String getcombinedLtv();
}
The problem is: when the findLeads() repository method is called the following error occurs:

I first started trimming my Aggregation logic thinking that maybe there is a problem with it (the aggregation works fine in Mongo Compass and Atlass) and i ended up having only the $match operator (something very basic) and still the error persisted.
#Aggregation(pipeline = {"{$match: {\r\n" +
" 'status':{$in: ?0},\r\n" +
" 'loanApplication.mortgage.requested.lenderSubmission.lenderProfile.lenderCode': ?1\r\n" +
" }}"})
public List<LoanProjection> findLeadsTest(final List<Integer> leadsStatus, final String lenderCode);
Then I wanted to see if by utilising the #Query annotation i would receive the same error. Funny enough with this method the projection worked!!!
#Query(value = "{$and: [{'status': {$in: ?0}}, {'loanApplication.mortgage.requested.lenderSubmission.lenderProfile.lenderCode': ?1}]}")
public List<LoanProjection> findLeads(final List<Integer> leadsStatus, final String lenderCode);
Therefore my question is: is somehow spring projection not compatible with #Agregation or am i using it wrong (most likely)?

I think you would need to use a class instead of an interface and you need to add the #Id annotation in order to match the result from the aggregation
In your case is very hard to follow exactly what would be the id, because you didn't added any result from running the aggregation manually in mongo from CLI.
But if I try to guess then something like this probably would help you:
import org.springframework.data.annotation.Id;
// other imports
public class LoanProjection {
#Id
private DealType dealType;
private LocalDate receivedDate;
DealType getDealType() {
return dealType;
}
LocalDate getReceivedDate() {
return receivedDate;
}
}
public class DealTypeProjection {
#Id
private String applicationId;
private String combinedLtv;
public String getApplicationId() {
return applicationId;
}
public String getCombinedLtv() {
return combinedLtv;
}
}
Usually the result from an aggregation is very different than the Document used so you would need to have some unique identifier in order to map it to a new Projection. You could look at the result from aggregation like a new Document because this is the way spring matches the result with actual DTO.
More details here:

ElasticSearch RestHighLevelClient throws java.io.IOException: Connection reset by peer

Summary
When my Spring Boot app has been idle for a while, calling the search method of an ElasticsearchRepository (which uses the RestHighLevelClient for the underlying ES connection) results in a java.io.IOException: Connection reset by peer being thrown.
Detailed problem
I have a Spring Boot app (version 2.2.4.RELEASE) and an ElasticSearch (version 6.8.6). For communication with the ES instance I use Spring Data Elasticsearch (version 3.2.5.RELEASE), to be specific I use an ElasticsearchRepository.
My ES configuration class looks as follows:
#Configuration
#EnableElasticsearchRepositories
public class ElasticsearchConfiguration {
private final RestHighLevelClient restHighLevelClient;
#Autowired
public ElasticsearchConfiguration(RestHighLevelClient restHighLevelClient) {
this.restHighLevelClient = restHighLevelClient;
}
#Bean
public ElasticsearchRestTemplate elasticsearchTemplate() {
return new ElasticsearchRestTemplate(restHighLevelClient);
}
}
I have got an REST endpoint which triggers a lookup in the ES by calling the below method:
#Service
#Transactional(readOnly = true)
public class SportsFacilityViewFilterService {
private final SportsFacilityViewRepository sportsFacilityViewRepository;
#Autowired
public SportsFacilityViewFilterService(SportsFacilityViewRepository sportsFacilityViewRepository) {
this.sportsFacilityViewRepository = sportsFacilityViewRepository;
}
/**
* Retrieves all {#link SportsFacilityView}s stored in the search index that match the given filter parameters.
*
* #param activity filter parameter.
* #param city filter parameter.
* #param date filter parameter.
* #param capacity filter parameter.
* #return {#code List<SportsFacilityView>} the filtered sports facilities in a display optimized format.
*/
#Retryable(include = IOException.class, maxAttempts = 1, backoff = #Backoff(delay = 15))
#Transactional(readOnly = true)
public List<SportsFacilityView> filterSportsFacilities(final String activity, final Integer capacity,
final String city, final LocalDate date) {
// Use filter query to retrieve sports facility views
final NativeSearchQuery searchQuery = new NativeSearchQueryBuilder()
.withFilter(buildFilterQuery(activity, capacity, city))
.withPageable(PageRequest.of(0, 50))
.withSort(new FieldSortBuilder("vendorName").order(SortOrder.ASC))
.build();
final List<SportsFacilityView> sportsFacilities = Lists.newArrayList(sportsFacilityViewRepository.search(searchQuery));
// Post-process filter results
removeClosedSportsFacilities(sportsFacilities, date);
updateMinimumPrice(sportsFacilities, date);
// Return
return sportsFacilities;
}
}
I defined the SportsFacilityViewRepository as follows:
#Repository
public interface SportsFacilityViewRepository extends ElasticsearchRepository<SportsFacilityView, Long> {
}
This code works perfectly fine, but when the system has been idle for a while, the following exception is thrown when invoking the above illustrated method:
org.springframework.data.elasticsearch.ElasticsearchException: Error for search request with scroll: SearchRequest{searchType=DFS_QUERY_THEN_FETCH, indices=[sportsfacility], indicesOptions=IndicesOptions[ignore_unavailable=false, allow_no_indices=true, expand_wildcards_open=true, expand_wildcards_closed=false, allow_aliases_to_multiple_indices=true, forbid_closed_indices=true, ignore_aliases=false, ignore_throttled=true], types=[sportsfacilityview], routing='null', preference='null', requestCache=null, scroll=null, maxConcurrentShardRequests=0, batchedReduceSize=512, preFilterShardSize=128, allowPartialSearchResults=null, localClusterAlias=null, getOrCreateAbsoluteStartMillis=-1, source={"from":0,"size":50,"post_filter":{"bool":{"filter":[{"term":{"address.city":{"value":"Köln","boost":1.0}}}],"adjust_pure_negative":true,"boost":1.0}},"version":true,"sort":[{"vendorName":{"order":"asc"}}]}}

I tried forcing a retry by annotating the method with #Retryable, but unfortunately this appears to be ignored, despite being picked up in other places of the program.
Can somebody please explain why I get this exception and how I can prevent it from occurring?
Update
Removing the #Repository annotation from SportsFacilityViewRepository made it possible to try/catch the code, respectively automatically retry by means of the #Retryable annotation. Obviously, the Spring Exception Translation mechanism applied due to the #Repository annotation being present prevented a try/catch block and Spring Retry to catch the exception that was shown on the console.

I finally found an easily viable workaround. I let Spring execute a scheduled task which executes the count method of the relevant ElasticsearchRepositories. By that means, the connection is kept alive so that no Exceptions can occur due to the system being idle for too long.
The code looks as follows:
#Component
#Slf4j
public class ElasticsearchConnectionTester {
private final SportsFacilityViewRepository sportsFacilityViewRepository;
#Autowired
public ElasticsearchConnectionTester(SportsFacilityViewRepository sportsFacilityViewRepository) {
this.sportsFacilityViewRepository = sportsFacilityViewRepository;
}
#Scheduled(fixedRate = 1800000, initialDelay = 1800000)
public void keepConnectionAlive() {
log.debug("Trying to ping Elasticsearch");
try {
final long noOfSportsFacilities = sportsFacilityViewRepository.count();
log.debug("Ping succeeded for SportsFacilityViewRepository, it contains {} entities", noOfSportsFacilities);
} catch (Exception e) {
log.debug("Ping failed for SportsFacilityViewRepository");
}
}
}
The logging is optional, but it provides the necessary insight whether the chosen rate for the scheduled job is sufficient.

Here's some configuration:
#Configuration
public class ElasticSearchConfig extendsAbstractElasticsearchConfiguration {
#Value("${spring.elasticsearch.rest.uris}")
private String uris;
#Value("${spring.elasticsearch.rest.username:#{\"\"}}")
private String username;
#Value("${spring.elasticsearch.rest.password:#{\"\"}}")
private String password;
#Override
public RestHighLevelClient elasticsearchClient() {
final ClientConfiguration clientConfiguration = ClientConfiguration.builder()
.connectedTo(uris)
.withBasicAuth(username, password)
.withHttpClientConfigurer(clientBuilder -> {
clientBuilder.setKeepAliveStrategy((httpResponse, httpContext) -> 1000 * 60);
return clientBuilder;
})
.build();
return RestClients.create(clientConfiguration).rest();
}
}

Maybe you can config the client like this:
#Override
#Bean
public RestHighLevelClient elasticsearchClient() {
// Connect to elastic search in https://app.bonsai.io/
final ClientConfiguration clientConfiguration = ClientConfiguration.builder()
.connectedTo(hostAndPort)
.withBasicAuth(userName, pwd)
// config the connect
.withConnectTimeout(5000)
.withSocketTimeout(60000)
.build();
return RestClients.create(clientConfiguration).rest();
}

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());
history.setClose(entry.getValue().getAsJsonObject().get("close").getAsFloat());
eachStock.add(history);
});
} catch (Exception e) {
continue;
}
if (eachStock.size() >= historyLength) {
stockHistory.addAll(eachStock);
}
}
if (stockHistory.size() > 0) {
stockHistoryRepository.saveAll(stockHistory);
}
}
The controller to display the data on the web page:
#GetMapping("/symbol/add/{symbol}")
public String addToPortfolio(#PathVariable("symbol") String symbol) throws Exception {
StockSymbol symbolData = stockSymbolService.getStockBySymbol(symbol);
if (symbolData != null) {
User user = (User) SecurityContextHolder.getContext()
.getAuthentication().getPrincipal();
Optional<Investor> investorExist = investorService.findByUsername(user.getUsername());
if (investorExist.isPresent()) {
Investor investor = investorExist.get();
Set<Stock> stocks = investor.getPortfolio();
boolean found = stocks.stream()
.anyMatch(stock -> stock.getSymbol().equals(symbolData.getSymbol()));
if (!found) {
Stock newStock = new Stock();
newStock.setSymbol(symbolData.getSymbol());
newStock.setName(symbolData.getSymbolName());
newStock.setQuantity(1L);
boolean isAvailable = stockHistoryRepository.findAll()
.stream().anyMatch(stockHistory -> stockHistory.getSymbol().equals(symbolData.getSymbol()));
newStock.setHistoryAvailable(isAvailable);
stocks.add(newStock);
investor.setPortfolio(stocks);
stockRepository.save(newStock);
investorService.saveInvestor(investor);
stockRealTimeFetchService.fetchAndUpdateStockRealTime();
stockRealTimeFetchService.fetchAndUpdateStockHistoricalDataOneByOne();
} else {
return "errors/StockFoundError";
}
}
} else {
return "errors/StockNotFoundError";
}
return "redirect:/portfolio";
}
The error that may or may not happen is:

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.

Form Data Is Not Getting Validated Even If ExceptionHandler Is Defied

I'm implementing validation logic to the application. I have declared a class for custom validation logic. My class extends ResponseEntityExceptionHandler and overrides one method (handleMethodArgumentNotValid) to support #Valid and validate form data and I have some other methods for other exception propagation.
The problem I'm getting all custom exception is propagating to POSTMAN as JSON format but when I'm entering form data with wrong info it's ending with a java error and the overridden method is not getting called.
But I'm getting 200 as response and a blank data response not the validation error messages.
I have tried adding #Validated annotation along with #Valid annotation but it also didn't work.
I have added hibernate related validation annotation like #NotBlank(message=""), #NotNull(message="") in the pojo classes.
Though I'm getting the exception with the same message that I have provided in eclipse console but I'm not getting the desired response with the error messages in the postman.
Whenever I'm sending request from POSTMAN with incorrect form data and though #Valid annotation is there it should directly call the appropriate #ExceptionHandler annotated method but how it is propagating to the DAO with the null or incorrect values.
