@ManyToMany relationships, but QueryByExample seems to not filter with the values present in the @ManyToMany. I believe this is a bug, but I though it was wiser to ask here before opening an issue, as I may be wrong. Thanks in advance!

Hi, I'm using Spring Boot Webflux and Mongodb as database. In this project I have two submodules and my problem is related to @TypeAlias and _class generated by Spring data. My problem is that by default _class is taking the name of the entity class which is including the package name and its leading to inconsistency when the same Entity is used in different submodules:
- Api - submodule has this class name : com.example.api.MyEntity.class
- Worker - submodule has this class name: com.example.worker.MyEntity.class
So my question is how can I configure the base package name com.example.api and com.example.worker to custom.package?
One way is to use @TypeAlias but this is a pain to do for each entity.. Is there any alternative?
@Field(type = FieldType.Date, format = DateFormat.date) to LocalDate field in a nested object it is not used and I get a mapper_parsing_exception, has anyone already faced this issue before?

I'm having a strange issue. When i deploy an application the first time, everything starts and works fine. When the Wildfly server restarts, Spring Data Mongo hangs on the MongoPersistentEntityIndexCreator checkForIndexes for an entity. If i remove the deployment and deploy again it works.... any ideas? Not seeing any errors or debug messages that helps to find any possible issues.
I'm using Spring Data Mongo 2.2.9, Mongo Driver Sync 3.11.2 and Wildfly/Keycloak 11.0.1
jakarta.persistence-api 3.0)? If so, then Spring Framework and all downstream projects (Spring Data, Spring Boot) need to be migrated. Eclipselink 3.0 is available but there's no Hibernate release supporting Jakarta Persistence 3.0 yet.
Hello guys, I have a small issue (migrating to springboot 2.4.4) -> Spring Data Redis - Could not safely identify store assignment for repository candidate interface MyJpaRepositoryIf you want this repository to be a Redis repository, consider annotating your entities with one of these annotations: org.springframework.data.redis.core.RedisHash
The problem is that this repository is extending JpaRepository and is supposed to work with Postgresql. The one for Redis have the @RedisHash stuff.
How can I get away of such messages ? Thank you in advance

Hi all. I'm trying to understand something about spring-data-elasticsearch. I'm using the reactive version of it, however I've just run BlockHound from Project Reactor and discovered that some part of the inner logic of FieldSortBuilder is blocking (java.io.FileInputStream#readBytes), so when I trigger the search method on ReactiveElasticsearchOperations with my query, which includes the sorting, I'm getting a blocked call. This is what the output from BlockHound looks like (I've shortened it a bit)

Hello, I have 7 repositories (2 Redis, 5 JPA)
I used specific base package with filter for all of them in annoattions (@EnableSpringRedis() @EnableSpringJpa() so that spring data have no confusion
But at startup this takes more than 3 minutes:
RepositoryConfigurationDelegate.multipleStoresDetected: Multiple Spring Data modules found, entering strict repository configuration mode!
RepositoryConfigurationDelegate.registerRepositoriesIn:
Bootstrapping Spring Data Redis repositories in DEFAULT mode. // < --------- this takes 3 minutes
RepositoryConfigurationDelegate.registerRepositoriesIn:
Finished Spring Data repository scanning in 303059 ms. Found 2 Redis repository interfaces.
RepositoryConfigurationDelegate.registerRepositoriesIn:
Finished Spring Data repository scanning in 77 ms. Found 5 JPA repository interfaces.why is it so slow ? (Migrated to last version of spring 2.4.4 (and it takes spring-data-redis 2.4.6)
thank you in advance

Hey all,
Im quite new to Spring Data and working with Databases in general and was just wondering how you might go about solving a specific issue. With Spring Data and with MongoDB (I anticipate the database is not so relevant here)
I have this code
Optional<Parent> optionalParent = parentRepository.findById("someId");
if (optionalParent.isPresent()) {
Parent parent = optionalParent.get();
Child child = new Child("some value");
parent.getChildren().add(child);
parentRepository.save(parent);
}The issue is that, if there were multiple threads or instances which are running this code then there maybe a concurrency issue as the "Get the parent", "Add child to parent" and "Save Parent" stages together are not atomic and therefore could end up with child's being overwritten.
How would this situation normally be resolved?
@Version property to your document entity will let Spring Data consider the current version of your document. Each update increments the version. On a concurrent update, there can be only one winner and the other one will receive an OptimisticLockingFailureException. Spring Data MongoDB adds the version number to the update filter and checks how many documents were updated. Does that help?
Hello,
I'm using spring-data-rest with QueryDsl, and I'm experiencing weird behaviour.
With the filter http://my.service/users?roles=2&roles=5, I'm getting all users with roles 2 AND 5.
With the filter http://my.service/users?roles.id=2&roles.id=5, I'm getting all users with roles 2 OR 5.
The reason lies in QuerydslDefaultBinding.java since the first path ends up in the CollectionPathBase branch and the second in the SimpleExpression branch.
While I like that I have both options, I find this very unintuitive. I would have guessed, that the first query would be just a shorthand for the second.
I'm now wondering what is the rationale behind this behaviour.
Regards
@Query(value = "SELECT 1 WAITFOR DELAY '0:05'")
void waitforSQL();Hi Mark @mp911de. I seem to have a problem with spring-data-elasticsearch (SDE) when going from spring-boot 2.4.4 (4.1.6 SDE) to 2.5.0-M3 (4.2.0-M5 SDE). Some of the fields in one of my domain classes is defined like this:
@Field(name = FIELD_VERSION_UPDATE_TIME, type = FieldType.Date, format = DateFormat.date_optional_time)
private LocalDateTime versionUpdateTime;and I'm now getting errors like org.springframework.data.elasticsearch.core.convert.ConversionException: could not create object of class java.time.LocalDateTime when running my tests. Is there something extra I need to specify with the dateformat? Thanks for your help

I have lettuce client with springboot 2.3.9.RELEASE to connect AWS redis elasticcache master/slave.
I'am able to write and read but a error is thrown every 5000ms
The service works fine for my pourpose but I want to remove the error or how to know to fix it.
I've read a lot about it and the best way to configure spring data redis with lettuce ans AWS is using RedisStaticMasterReplicaConfiguration to write to master and read from replica.
This is the bean configuration
@Bean
public LettuceConnectionFactory redisConnectionFactory() {
LettuceClientConfiguration.LettuceClientConfigurationBuilder lettuceConfigBuilder = LettuceClientConfiguration.builder()
.readFrom(ReadFrom.REPLICA_PREFERRED);
lettuceConfigBuilder.useSsl();
RedisStaticMasterReplicaConfiguration redisConfiguration = new RedisStaticMasterReplicaConfiguration(master, port); //master value is the Primary Endpoint value from aws elasticcache info
redisConfiguration.addNode(replica, port); //replica value is the Reader Endpoint value from aws elasticcache info
redisConfiguration.setPassword(password);
return new LettuceConnectionFactory(redisConfiguration, lettuceConfigBuilder.build());
}When application is started I'm able to write and read but every 5 seconds an error is thrown from RedisMessageListenerContainer
"level":"ERROR","className":"org.springframework.data.redis.listener.RedisMessageListenerContainer","message":"Connection failure occurred. Restarting subscription task after 5000 ms "But this is the original error from RedisMessageListenerContainer.handleSubscriptionException
java.lang.UnsupportedOperationException: Pub/Sub connections not supported with Master/Replica configurationsGood evening all. I need some help with the health check of Elasticsearch. I'm using Spring Boot 2.5.0-M3 and spring-data-elasticsearch 4.2.0-M5 and I'm using the ReactiveElasticsearchClient.
When checking /actuator/health locally it works fine, however after I've deployed to Kubernetes the heath check keeps reporting
elasticsearch: {
status: "DOWN",
details: {
statusCode: 401,
reasonPhrase: "Unauthorized"
}I have set the following properties but without any luck.
spring:
elasticsearch:
rest:
uris: ${ELASTICSEARCH_HOST}
password: ${ELASTICSEARCH_PWD}
username: ${ELASTICSEARCH_USER}I can use those credentials and successfully call the /_cluster/health endpoint through Postman, so why does it give me a 401 when Spring Boot tries to call?
Am I missing something? Thank you

@Query("DELETE FROM SESSION_CLIP WHERE SESSION = :session") with the following derived delete query void deleteBySession(UUID session);, which raises the following exception when executed: NoSuchMethodException: void.<init>(). It seems to have something to do with a missing default constructor, but I'm not sure why that would be needed here?
Hi All,
I'm looking for ideas what's the best approach when storing data using DATA JPA and using Kotlin.
Entity example
@Entity(name = "COUNTRIES")
data class Country(
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
val id: Long = 0,
val name: String,
val countryCode: String,
val flagUrl: String? = null,
@OneToMany(mappedBy = "country")
val venues: Set<Venue> = setOf(),
@OneToMany(mappedBy = "country")
val teams: Set<Team> = setOf(),
@OneToMany(mappedBy = "country")
val leagues: Set<League> = setOf()
)I wanna store the entity while providing only the name, countryCode and flagUrl.
Ideas I came up with:
- set
venues,teams, andleaguesas nullable and set default value as null. - move those 3 properties to the body of the class instead of keeping it in the constructor.
- Keep as is and set the default value as empty
Set.
Any other ideas or an idea what would be the best approach?
