‘Authentication object cannot be null’ error when query method is performed in open endpoint

I have public method checkProfileToken in AuthenticationController that grabs some information from the Neo4j database using the Neo4jRepository implementation - ProfileRepository.
I’ve ignored Spring Security for this request /check_profiletoken in OAuth2SecurityConfiguration class:
#Configuration
#EnableWebSecurity
public class OAuth2SecurityConfiguration extends WebSecurityConfigurerAdapter {
// …
#Override
public void configure(WebSecurity webSecurity) {
webSecurity.ignoring().antMatchers("/check_profiletoken"); // ingoring WebSecurity for this entry
}
// …
}
Controller (AuthenticationController.java):
#RestController
public class AuthenticationController {
#Autowired
ProfileRepository profileRepository;
// …
#RequestMapping(method = RequestMethod.POST, value = "/check_profiletoken")
public ResponseEntity<?> checkProfileToken(#RequestBody final JSONObject jsonRequest) {
// HTTP response container
HttpHeaders responseHeaders = new HttpHeaders();
responseHeaders.setLocation(ServletUriComponentsBuilder.fromCurrentRequest().buildAndExpand().toUri());
final String token = (String) jsonRequest.get("token");
Integer tokenType = null;
try {
tokenType = (Integer) jsonRequest.get("tokentype");
} catch (Exception e) {
return new ResponseEntity<>(
new ActionResponseDTO(
new ActionResponseItemDTO(ActionResponseTypes.ERROR, ActionResponseCodes.INVALID_DATA,
ActionResponseDomains.PROFILE_TOKEN, null, "Token type is invalid!")),
null, HttpStatus.BAD_REQUEST);
}
ActionResponseDTO actionResponses = commonService.checkProfileToken(token,
ProfileTokenType.getByCode(tokenType));
if (actionResponses.isValid()) {
return new ResponseEntity<>(actionResponses, responseHeaders, HttpStatus.OK);
} else {
return new ResponseEntity<>(actionResponses, responseHeaders, HttpStatus.BAD_REQUEST);
}
}
// …
}
In method checkProfileToken I call getProfileForActivation query method of the ProfileRepository
Repository (ProfileRepository.java):
#Repository
public interface ProfileRepository extends Neo4jRepository<Profile, String> {
// …
#Query("MATCH (p:Profile)-[r:HAS_PARENT]->(g:Group) WHERE p.uuid=$profileId RETURN g.displayName as companyName, p.honorificPrefix as honorificPrefix, p.givenName as givenName, p.familyName as familyName, p.gender as gender")
ProfileActivation getProfileForActivation(#Param("profileId") String profileId);
// …
}
Here is an error that I got when performing query above:

#RestControllerAdvice in not getting instantiated

I wish to handle some internal server error (code: 500 ) using #RestControllerAdvice and #ExceptionHandler, unfortunately, nothing worked out for me.
package com.ocx.dlx.globalexception;
#RestControllerAdvice(basePackages = "com.ocx.dlx.controller")
public class GlobalExceptionHandler extends ResponseEntityExceptionHandler {
#ExceptionHandler(value = RuntimeException.class)
public ResponseEntity<InternalErrorResponse> handleInternalServerError(RuntimeException ex, WebRequest request) {
InternalErrorResponse exceptionResponse = InternalErrorResponse.builder()
.code(SecurityConstants.INTERNAL_SERVER_ERROR).msg("internal server exception raised").build();
return new ResponseEntity<>(exceptionResponse, HttpStatus.INTERNAL_SERVER_ERROR);
}
}
some of my controllers are in the package com.ocx.dlx.controller and my application class is in com.ocx.dlx package.
I tried all possible solutions given in StackOverflow and some other sites, still, the RestControllerAdvice annotated class is not being invoked.
I have tried the below:
enabling WebMvc i.e #EnableWebMvc
packaging structure
changed all the exceptions in #ExceptionHandler()
mvn clean
project clean and start
changed the generic type to ResponseEntity<Object>
without extending ResponseEntityExceptionHandler
Your help would really get me some sleep this night.... m struggling for a day. Thanks in advance

LazyInitializationException in Spring (Not thrown often)

An org.hibernate.LazyInitializationException is thrown in the application and my challenge not being able to replicate it.
Entity: OrderDetail.java has
/** The order discounts. */
#OneToMany(mappedBy = "orderDetail", fetch = FetchType.LAZY, orphanRemoval = true, cascade = CascadeType.ALL)
private Set<OrderDiscount> orderDiscounts = new HashSet<>();
public Set<OrderDiscount> getOrderDiscounts() {
return orderDiscounts;
}
public void setOrderDiscounts(Set<OrderDiscount> orderDiscounts) {
this.orderDiscounts = orderDiscounts;
}
ReadOnlyOrderDetail.java, I am initializing the constructor as below
public ReadOnlyOrderDetail(OrderDetail orderDetail, boolean isDiscountsRequired) {
//setting other properties
if (isDiscountsRequired) {
Optional.ofNullable(orderDetail.getOrderDiscounts()).ifPresent(orderDiscounts -> {
orderDiscounts.forEach(discounts -> {
// sets discount
});
});
}
}
Point to note here is that orderDetail.getOrderDiscounts() comes off as empty Set and code inside If{} doesn't get executed, that's what I've seen so far. But still what's confusing to me is this in the log: java.base/java.lang.Iterable.forEach(Iterable.java:74)
Now, OrderDetail is an Entity class. OrderDetail is be mapped to ReadOnlyOrderDetail - which is a model class, is used to generate the Json response to be returned.
And the exception occurs when ReadOnlyOrderDetail object gets initialized in the Constructor. To be specific, it happens # orderDetail.getOrderDiscounts() is what I understand. This is not a consistent behaviour but has something to do with the session, I guess
Any thoughts on this is much appreciated.
Posting the exception thrown for your reference:

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();
}
