How test a method with #Transactional annotation

how can i test a method with the #Transaction annotation.
I wrote a method which works if i test it when the application is running (manually). But my test for this doesn't work. My goal is to write a test which make sure that my transaction method works when a exception happened, so nothing is stored in the DB. Maybe it is enough to test that the Transaction annotation exist, in the belief that spring works fine. :/
But that is ugly for me.
So my goal is not to test the functionality of springs transaction. My goal is to have a test which make sure that nothing will be stored in the db if a exception happen. Maybe there is a better way to test it.
I drop every time the database before the test is running.
The id of the company is every time a another random long.

THANK YOU FOR YOUR HELP

Personally I would not write a unit test to test that #Transactional works correctly. My reason is, the environment for the unit test execution is not the same as the environment the bean works in. I have seen too many cases where the unit tests work fine, but the actual system does not.
You can rather try to write an integration tests that will run against an instance of the system (send a request, trigger the functionality, look into the DB to see whether it is what you expect to see). Makes more sense to me, but may also be more time consuming to do.

So i found a solution which works for me. I annotated my test class with
#DataMongoTest(excludeAutoConfiguration = EmbeddedMongoAutoConfiguration.class, includeFilters = #ComponentScan.Filter(Component.class))
#ActiveProfiles("test")
class CompanyServiceMongoTest {}
I don't know why the annotation #SpringBootTest doesn't work. I thought that #SpringBootTest is a "super context" of #DataMongoTest, but my tests doesn't work with #SpringBootTest annotation. Be aware to use #Transactional as annotation in the test class layer. It doesn't work fine with the transaction mechanism in the service.

Why is it trying to connect to localhost when I have specified host name explicitly in yml file? Any Idea?

Just found out that in yml file I have a profile named as heroku, when I removed it , it connected to the RabbitMQ in the given host.

If you are using spring boot you can configure Rabbit by spring cloud stream.
In this case you dont have to configure the beans and the configuration is much easier:
spring:
#---------------- RabbitMQ -----------------#
rabbitmq:
#Default username ans pass
dynamic: true
host: localhost
port: 5672
username: guest
password: guest
#---------------------------- RabbitMQ properties Commons ------------------------------#
cloud:
stream:
bindings:
springCloudBusInput:
destination: InputExchange
group: Queue
producer:
exchangeAutoDelete: false
springCloudBusOutput:
destination: InputExchange
group: Queue
consumer:
exchangeAutoDelete: false
Then you have to create the listener:
#Component
public class RemoteEventListener implements ApplicationListener<InputEvent> {
#Override
public void onApplicationEvent(InputEvent inputEvent) {
//whatever you want to do when a InputEvent Type is received in the queue
}
}
In this case My app is writing and receiving from the same exchange
and queue (Because of testing so stuff)
If you want to configure rabbit the way you shown, try to create a configuration class with the beans of the queue, exchange and biding with #Configuration. Dont declare the beans in your app class.
It seems it can not read the autodelete property of the queue, but if I'm not wrong I should take the default.
Maybe You have network issues
Check the rabbitmq and restart it
Can you acces to rabbitMq administrator interface?
About the comment about whi is trying to connect with localhost add this to your bean definition:
#Autowired
private ConnectionFactory rabbitConnectionFactory
#Bean
public RabbitTemplate rubeExchangeTemplate() {
RabbitTemplate r = new RabbitTemplate(rabbitConnectionFactory);
r.setExchange("rmq.rube.exchange");
r.setRoutingKey("rube.key");
r.setConnectionFactory(rabbitConnectionFactory);
return r;
}
also remove addresses of your application.yml

Could not locate PropertySource: I/O error on GET request for "http://localhost:8761/config/diviso/dev/master": Connection refused: connect; nested exception is java.net.ConnectException: Connection refused
This warning message means that your application could not connect to its spring cloud config server: JHipster Registry.
In dev profile, this is just a warning that you can ignore as your application can run with local application properties in sc/main/resources/config.
In prod profile, this would be an error and your application would not start. The registry must be started before your app because this is where your app gets its application properties from and registers itself as an Eureka client.
So in dev, you can ignore this warning or if it annoys you, you can start a registry.
If your app is a monolith application and not a microservice application, you can opt out the discovery client question, it'll be simpler to deploy if you don't need horizontal scaling.

The same issue happened with me, although I have already generated and modified my project before.
In case you are using MySql, go to phpMyAdmin page and type in your credentials. Worked for me.

Embedded Tomcat won't listen to port 80 in AWS Elastic Beanstalk

I'm launching a Spring Boot .jar with Embedded Tomcat to an Elastic Beanstalk (Java) instance.
server.port=80 in the configuration file, however EB won't let Tomcat bind to port 80.
What's preventing Tomcat from listening to port 80 and how do I fix it?
Here's the pertinent section of the logs:

I assume topic starter already resolved this problem, but I'll post my solution here for the new people who'll be stuck on the same issue.
I've made my Spring Boot application accessible from port 80 on AWS Elastic Beanstalk by setting environment property SERVER_PORT to 5000 (you can set it in "Configuration" > "Software Configuration").

Cannot connect to jhipster spring registry on docker via IDE

I'm running JHipster registry in a docker container.
All applications running on docker can connect and register in registry endpoint (port 8761).
But when I try to connect an application running on my IDEA, I receive a error when trying to connect to the registry endpoint:

The application connects to Register (see it in logs), but after that I receive the error:
UnknownHostException: registry
Did anyone know how can I connect to a registry running in docker?
My spring application.yml is:
eureka:
instance:
prefer-ip-address: true
client:
enabled: true
healthcheck:
enabled: true
registerWithEureka: true
fetchRegistry: true
serviceUrl:
defaultZone: http://admin:admin#localhost:8761/eureka/
The default zone in jhipster-registry is http://user:pass#register:8761/eureka.
If I change to localhost, like this:
eureka:
client:
serviceUrl:
defaultZone: http://admin:admin#localhost:8761/eureka/
It works, but in this case the services running in docker can't access the registry (reverse problem).
Thanks!

I had a similar issue. In 3.5.0, I was able to successfully start the docker based registry, and then start up non docker versions of a microservice and a gateway. With 3.5.1, I was no longer able to do that, getting the same error you are getting. I think it's related to https://github.com/jhipster/generator-jhipster/pull/3848. In any case, I just added an entry in my /etc/hosts file, pointing "registry" to 127.0.0.1, and it worked.

The localhost on docker which running microservice is not the same localhost on docker which running registry. I changed the localhost to the host's Intranet Address, It's work for me.
eureka:
instance:
prefer-ip-address: true
client:
service-url:
defaultZone: http://admin:${jhipster.registry.password}#10.31.224.228:8761/eureka/
