Spring Batch StoredProcedureItemReader for PostgreSQL - java.lang.IllegalStateException - java

I am getting illegal state exception. I tried to resolve it by setting following parameters
etlReader.setSaveState(false);
etlReader.setUseSharedExtendedConnection(false);
Do anyone has clue what is going on?
My configuration in application.properties as follows:
spring.datasource.url=jdbc:postgresql://localhost:5432/
spring.datasource.username=user
spring.jpa.database-platform=org.hibernate.dialect.PostgreSQLDialect
spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation=true
spring.jpa.show-sql=true spring.batch.initialize-schema=always
#Scheduled param
etl.scheduler.frequency=3600000
This is the important part of ItemReader implementation. Please let me know if any additional information is required.
#SuppressWarnings("rawtypes")
#Bean
public StoredProcedureItemReader generateEvents(DataSource dataSource) {
StoredProcedureItemReader<Event> etlReader = new StoredProcedureItemReader<Event>();
etlReader.setDataSource(dataSource);
etlReader.setProcedureName("myStoredProcedure");
etlReader.setFunction(false);
etlReader.setRowMapper(etlNoOpRowMapper());
return etlReader;
}
#Bean
public NoOpEventETLWriter etljobWriter() {
return new NoOpMyDataETLWriter();
}
#Bean(name = "executeETLStep")
public Step executeETLStep(ItemReader<Event> generateEvents) {
return stepBuilderFactory.get("executeETLStep").<MyData, MyData>chunk(1).reader(generateEvents)
.writer(etljobWriter()).build();
}
#Bean(name = "etlJob")
public Job etlJob(CardinalBatchCompletionListener listener, #Qualifier("executeETLStep") Step executeETLStep) {
return jobBuilderFactory.get("etlJob").incrementer(new RunIdIncrementer()).listener(listener)
.flow(executeETLStep).end().build();
}

EDIT
All my beans are in configuration file, so they are initialized as soon as I start. And running the job using a scheduler. Why is job execution again trying to reinitialize the resources?


If your scheduler runs two job instances simultaneously, then the reader will be shared, which is the cause of your issue: One job opens the reader, then before closing it, another job tries to open it as well.
You need to make your reader job scoped (step scoped would also work).

JavaEE can't create connection with docker's MySQL container

Salute, guys, I was creating my application on JavaEE using as database MySQL. It works correctly, but now i need to run mysql server from docker container. Here I got problems. I am demonstrating my code https://github.com/MatveyAndrosyukk/javaee_rest_jdbc_todo_list:
1.My DataSourse URL:
final static String URL = "jdbc:mysql://localhost:3306/javaee_task_db?useSSL=false";
2.My URL from pom.xml in FlyWay configuration:
<plugin>
<groupId>com.googlecode.flyway</groupId>
<artifactId>flyway-maven-plugin</artifactId>
<version>1.5</version>
<configuration>
<user>user228</user>
<password>user228</password>
<driver>com.mysql.jdbc.Driver</driver>
<url>jdbc:mysql://mysql_db:3306/javaee_task_db?autoReconnect=true&useUnicode=true&characterEncoding=UTF-8&connectionCollation=utf8_general_ci&characterSetResults=UTF-8</url>
</configuration>
</plugin>
3.I started MySQL container using Docker: docker run --name mysql_db -p 3308:3306 --hostname=mysql_db -e MYSQL_ROOT_PASSWORD=secret -e MYSQL_DATABASE=javaee_task_db -e MYSQL_USER=user228 -e MYSQL_PASSWORD=user228 -v $HOME/mysql-data:/var/lib/mysql -d mysql:8.0
4.Then I changed DataSourse connection URL and did the same in pom.xml:
final static String URL = "jdbc:mysql://mysql_db:3306/javaee_task_db?useSSL=false";
5.Thy to start my application and get errors:
The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.

java.lang.NoSuchMethodError: 'com.google.api.gax.rpc.StubSettings$Builder com.google.cloud.pubsub.v1.stub.SubscriberStubSettings$Builder.setBackground

Im am trying to use google cloud pubsub with actuator but when I call /actuator/health the program throws the following exeption:

Line that throws error is that, saying that method does not exists.
DefaultSubscriberFactory.java#L398
ExecutorProvider executor = getExecutorProvider(subscriptionName);
if (executor != null) {
subscriberStubSettings.setBackgroundExecutorProvider(executor);
}
I tried to modify versions of the libs without success.
Spring Boot version 2.3.1.RELEASE
implementation 'org.springframework.integration:spring-integration-core'
implementation platform('com.google.cloud:spring-cloud-gcp-dependencies:3.2.1')
implementation 'com.google.cloud:spring-cloud-gcp-starter'
implementation 'com.google.cloud:spring-cloud-gcp-starter-pubsub'

That's a given fact; it only uses com.google.api.gax.core.InstantiatingExecutorProvider:
See SubscriberStubSettings.java

Why am I obtaining this error response trying to execute a simple GET all to a REST API using Spring RestTemplate?

I am working on a Spring Boot project and I am finding some difficulties trying to perform a simple GET API call using Spring Template (it works without problem for other APIs call into my project).
Basically I have this method:
private NotaryDistrict fetchNotaryDistrictDetailsFromAPI() throws KeyManagementException, UnrecoverableKeyException, NoSuchAlgorithmException, KeyStoreException, CertificateException, IOException {
System.out.println("fetchNotaryDistrictDetails() START !!!");
LOGGER.debug("Notary deiscrit details URL: {}", notaryDistrictDetailsURL);
ResponseEntity<NotaryDistrict> response = restTemplate.getForEntity("https://MAYPI.SERVICE.it/ws-application/service/distretti/CG7drXn9fvA%253D", NotaryDistrict.class);
NotaryDistrict notaryDistrictDetails = response.getBody();
System.out.println("notaryDistric details: " + notaryDistrictDetails);
return notaryDistrictDetails;
}
At the moment I directly mocked the API URL as parameter of the getForEntity() method. As you can see the API endpoint URL end with a query parameter representing the ID of the object that I want to retrieve (in this specific case CG7drXn9fvA%253D).
The problem is that when perform this line:
ResponseEntity<NotaryDistrict> response = restTemplate.getForEntity("https://MAYPI.SERVICE.it/ws-application/service/distretti/CG7drXn9fvA%253D", NotaryDistrict.class);
it throw this exception:

This error section is in italian:
org.springframework.web.client.HttpClientErrorException$BadRequest: 400 Bad Request: [{"errors":["Parametro IdDistrict non valido."]}]
the error meaning is: "IdDistrict parameter is not valid".
The strange thing is that performing the same API call (the same endpoint) via cURL or via PostMan it woks fine, as you can see here:
It seems that the problem is related to the ID of the object that I want to retrieve: CG7drXn9fvA%253D because in Postman I obtain the same error if i put an invalid ID:
I suspect that maybe the problem could be related to the fact that this ID contains the "%" character.
What can I try to do to solve this problem and obtain the expected output from my call?

Try to perform the API call by providing problematic identifier (since it might contain special charaters like '%' which are used for URL encoding) as a third parameter to getForEntity method call. This way the endpoint URL should be properly encoded. Therefore, the following should help:
ResponseEntity<NotaryDistrict> response = restTemplate.getForEntity(
"https://MAYPI.SERVICE.it/ws-application/service/distretti/{id}",
NotaryDistrict.class, "CG7drXn9fvA%253D");

Solved by myself performing the call in this way:
String url3 = "https://MYAPY.XXX.it/ws-application/service/distretti/{id}";
url3 = url3.replace("{id}", "CG7drXn9fvA%253D");
URI uri = new URI(url3);
System.out.println(uri);
ResponseEntity<String> forEntity2 = restTemplate.getForEntity(uri, String.class);
System.out.println(forEntity2.getStatusCodeValue());
System.out.println(forEntity2.getBody());

Make sure id in URL decoded:
%253D is the encoded chars of =. It seems the encoding applied twice and then the id was wrong. make sure id in URL is decoded
private NotaryDistrict fetchNotaryDistrictDetailsFromAPI() throws KeyManagementException, UnrecoverableKeyException, NoSuchAlgorithmException, KeyStoreException, CertificateException, IOException {
System.out.println("fetchNotaryDistrictDetails() START !!!");
LOGGER.debug("Notary deiscrit details URL: {}", notaryDistrictDetailsURL);
ResponseEntity<NotaryDistrict> response = restTemplate.getForEntity("https://MAYPI.SERVICE.it/ws-application/service/distretti/CG7drXn9fvA=", NotaryDistrict.class);
NotaryDistrict notaryDistrictDetails = response.getBody();
System.out.println("notaryDistric details: " + notaryDistrictDetails);
return notaryDistrictDetails;
}

Why is h2.jdbc throwing an exception when using h2 in-memory database for integration tests?

why not a dupe:
In my opinion this is not a duplicate question because I wasn't looking for solution which is written in the exception itself. I am looking for clarification what really is happening and why is this exception thrown. Linked post doesn't say anything about this.
I want to avoid using "production" database to run tests so I am using in-memory database for testing. I wrote a simple test for dao function and it passes but after finishing every test there is also an exception thrown. This exception doesn't fail any tests but I don't really know what is the reason (it doesn't point to any place in the code I have written) and whether it might lead to any undesired behaviours. Should I ignore it?

I have a Spring webapp that uses HttpInvoker to connect to a Spring Boot service.
I have recently updated the service project to use Java 11 and at the same time updated it to Spring Boot starter 2.1.3.RELEASE.
The service project provides an interface jar with all the request and response objects and the Interface classes required when using HttpInvoker.
I ran in to this error but only on some of the service endpoints.
I have been trying, without success, to pinpoint what the difference is between the successful requests and the failing ones.
Things I've tried to fix the issue
Both applications are running the same version of Java 11
Updated the Spring webapp to use Spring 5.1.5.RELEASE, this is the same version that comes with the spring boot starter.
Updated both apps to use spring-web 5.1.5.RELEASE. This is where the remoting library comes from
Made sure I have extends Serializable on my response objects and have updated the serialVersionUID
Confirmed that I am using the correct version of the service interface in my webapp
Can anyone point me in the right direction to get this solved...I'm really scratching my head on this now
The main issue with this error is that the service receives the request from the webapp, processes the request and then responds. Somewhere in the remoting callback I get this error and my webapp responds with an exception however in the background the request has completed successfully.
Below is part of the stacktrace, I have left some out on purpose, let me know if you require more information.
