Why your approach doesn't work
You're creating a flat result set from your one-to-many relationship between POSTS and COMMENTS, and then, you're expecting jOOQ's DefaultRecordMapper (via the fetchInto(Class) method) to de-duplicate those flat results again automatically for you. But that's not how things work in jOOQ. While you know the relationship between POSTS and COMMENTS in your query, a flat jOOQ Result does not. There's no obvious way how to auto-deduplicate stuff. Imagine, you had several nested collections in Post, how would that even work?
Using MULTISET to nest collections
The most jOOQ and SQL idiomatic way to nest collections is to use MULTISET, along with ad-hoc converters, e.g. like this:
List<Post> result =
dslContext
.select(
POSTS.ID,
POSTS.CONTENT,
POSTS.CREATED_AT,
multiset(
select(COMMENTS.ID, COMMENTS.CONTENT, COMMENTS.CREATED_AT)
.from(COMMENTS)
.where(COMMENTS.POST_ID.eq(POSTS.ID))
).convertFrom(r -> r.map(Records.mapping(Comment::new))))
.from(POSTS)
.fetch(Records.mapping(Post::new));


#Lukas Eder
I've written this method using multisetAgg. It works ok but i'm not sure it should look like this:
List<Post> getAllPost() {
List<Post> result =
dslContext
.select(
POSTS.ID,
POSTS.CONTENT,
POSTS.CREATED_AT,
multisetAgg(
COMMENTS.ID, COMMENTS.CONTENT, COMMENTS.CREATED_AT, COMMENTS.POST_ID
).as("comments").convertFrom(r -> r.into(Comment.class))
)
.from(POSTS)
.leftJoin(COMMENTS).on(COMMENTS.POST_ID.eq(POSTS.ID))
.groupBy(POSTS.ID)
.fetchInto(Post.class);
return result;
}

Eureka; cannot pass request through eureka server by restTemplate

Please help to solve the problem, I cannot make a request to the second application through the eureka service.
Here is my code:
EurekaServer:
#SpringBootApplication
#EnableEurekaServer
public class EurekaServerApplication {
public static void main(String[] args) {
SpringApplication.run(EurekaServerApplication.class, args);
}
}
server.port=8761
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false
Application client:
#SpringBootApplication
#EnableEurekaClient
public class ClientFirstApplication {
public static void main(String[] args) {
SpringApplication.run(ClientFirstApplication.class, args);
}
#Bean
#LoadBalanced
public RestTemplate getRestTemplate(){
return new RestTemplate();
}
}
#RestController
public class ClientFirstController {
#Autowired
public RestTemplate restTemplate;
#GetMapping("/connect-server")
public String serverFirstConnect(){
return restTemplate.getForObject("http://server/home-server", String.class);
}
}
server.port=8080
spring.application.name=client
eureka.client.service-url.defaultZone=http://localhost:8761/eureka/
Application Client2:
#SpringBootApplication
#EnableEurekaClient
public class ServerFirstApplication {
public static void main(String[] args) {
SpringApplication.run(ServerFirstApplication.class, args);
}
}
#RestController
public class ServerFirstController {
#GetMapping("/home-server")
public String home(){
return "<h1> This is Home page for Server First</h1>";
}
}
server.port=8081
spring.application.name=server
eureka.client.service-url.defaultZone=http://localhost:8761/eureka/
when I go to the link http://localhost:8080/connect-server, there is always an error

You should use EurekaClient to discover service instances from the Eureka Server as described in the documentation.
Try to define your controller in the way shown below.
#RestController
public class ClientFirstController {
#Autowired
public RestTemplate restTemplate;
#Autowired
private EurekaClient eurekaClient;
#GetMapping("/connect-server")
public String serverFirstConnect(){
String serverId = "server";
String homePageUrl = eurekaClient.getNextServerFromEureka(serverId, false).getHomePageUrl();
return restTemplate.getForObject(homePageUrl+"home-server", String.class);
}
}

Spring Cloud Stream - unable to serialize java class (works for java record)

Hi I am having an issue with new functional spring cloud stream...
I have a basic example:
#Autowired
private StreamBridge streamBridge;
#PostMapping("/publish/{topic}")
// fails
public boolean publish(#RequestBody MessageClass msg, #PathVariable String topic) {
// works
// public boolean publish(#RequestBody MessageRecord msg, #PathVariable String topic) {
return this.streamBridge.send(topic, msg);
}
Trying to simply as much as possible this is my java class:
public class MessageClass {
private String key;
private String content;
public MessageClass(String key, String content) {
this.key = key;
this.content = content;
}
public MessageClass() {
}
public String content() {
return content;
}
public String key() {
return key;
}
public void setKey(String key) {
this.key = key;
}
public void setContent(String content) {
this.content = content;
}
}
and record:
public record MessageRecord(String key, String content) {}
This fails for the MessageClass but succeeds with MessageRecord.
Relevant stack trace (I think, full below):
java.lang.ClassCastException: class io.enfuse.streamerrorexample.pkg.MessageClass cannot be cast to class [B (io.enfuse.streamerrorexample.pkg.MessageClass is in unnamed module of loader 'app'; [B is in module java.base of loader 'bootstrap')
at org.apache.kafka.common.serialization.ByteArraySerializer.serialize(ByteArraySerializer.java:19) ~[kafka-clients-3.1.1.jar:na]
See repo here: https://github.com/andyrewwer/spring-cloud-stream-error-example/settings/access
What is the difference between the java class and record and why does it work for record but not class?

Hibernate adding primary key of referred table in select

I have two entites: EntityA and EntityB
public class EntityA {
#Id
private Integer id;
private entityBKey;
#OneToOne(cascade = CascadeType.ALL)
private EntityB entityB;
}
public class EntityB {
#Id
private Integer id;
private entityBKey;
#OneToOne(cascade = CascadeType.ALL,mappedBy = "entityB")
#JoinColumn(name = "entityBKey", referencedColumnName = "entityBKey", insertable = false, updatable = false)
private EntityA entityA;
}
I am doing a join on entityBKey which is not a primary key in EntityB or even a declared foreign key in EntityA.
When I try to get data from EntityA, I get this error:
java.sql.SQLSyntaxErrorException: ORA-00904: "EntityA"."ENTITYB_ID": invalid identifier
I don't understand why is hibernate adding the primary key of EntityB in EntityA as EntityB_ID.
Please suggest what can I do get rid of this?
How I am reading EntityA:
Session session = sessionFactory.getCurrentSession();
CriteriaBuilder builder = session.getCriteriaBuilder();
CriteriaQuery<EntityA> criteriaQuery = builder.createQuery(EntityA.class);
Root<EntityA> from = criteriaQuery.from(EntityA.class);
criteriaQuery.select(from);
String queryString = session.createQuery(criteriaQuery).getQueryString();
System.out.println(queryString);
List<EntityA> entityAList = session.createQuery(criteriaQuery).getResultList();
session.close();
return entityAList;

RabbitMQ error java.util.concurrent.TimeoutException: null

I tried to build a simple consumer application with rabbitmq. My rabbit configured with rabbit:3-management image on port 15672, so, in theory, there is no problem at least in application properties.

The Default Port is: 5672.
It's defined in the RABBITMQ_NODE_PORT variable.
Source: https://www.rabbitmq.com/configure.html#define-environment-variables
Port 15672: It is used to access the management console of Rabbit MQ.
Change Port in property file from 15672 to 5672 and it will work!

How to create tables in Ignite using spring boot java?

I was implementing ignite using spring boot. I have configured my ignite instance using java only. I have also created two entity. I am able to use basic crud commands of ignite but I can't write my own sql query to query the tables. It's show IgniteException: table not found.
Item.java
import java.io.Serializable;
#Data
public class Item implements Serializable {

}
