I am using Keycloak Embedded in a Spring Boot Application which I imported the code from GitHub.
I got the following error when I run my application. I am using KeyCloak 11.0.2 version as you find the dependency below.

It's blocking my progress for few days. Please, I need help.
Thanks.
We have a Spring Boot 2.2.0.RELEASE application that we're testing with a JUnit 5 test class using WireMock. The test runs fine locally, but on our Jenkins, it fails with an "Address already in use" message after the test has run successfully.
Here's our spring dependencies from pom.xml:

So our test is pretty simple and looks like this:
#ExtendWith(SpringExtension.class)
#SpringBootTest
#ActiveProfiles("test")
#AutoConfigureWireMock(port = 0)
#Import(TestChannelBinderConfiguration.class)
class OurTestClass {
#Autowired
private OurDataCache cache;
#Autowired
private InputDestination source;
#Autowired
private OutputDestination target;
#BeforeEach
void setupApi() throws IOException, URISyntaxException {
stubFor(get("/endpoint")
.willReturn(aResponse()
.withStatus(200)
.withHeader("Content-Type", MediaType.APPLICATION_JSON_VALUE)
.withBody(data())
)
);
}
#Test
void sampleTest() {
String messageContent = loadResourceFileAsMessage("messageIn.json");
String expectedOutMessage = loadResourceFileAsMessage("messageOut.json");
Message<byte[]> message = new GenericMessage<>(messageContent.getBytes());
source.send(message);
Message<byte[]> received = target.receive();
assertThat(received, notNullValue());
assertThat(new String(received.getPayload()), equalTo(expectedOutMessage.replace(" ", "")));
}
}
Again, this runs fine locally, and on Jenkins, the actual test case passes, but then we get the error:

I also enabled DEBUG logging for the Spring WireMockConfiguration, and funnily enough, then the build succeeds. It does mention "Resetting mappings for the next test to restart them. That's necessary when reusing the same context with new servers running on random ports" after the test.
This makes me think this might be some sort of race condition, but I can't say I fully grasp the overall setup.
Any pointers would be helpful.
It's a known issue: https://github.com/spring-cloud/spring-cloud-contract/issues/665
You have to use #DirtiesContext in all tests that use WireMock or set spring.test.context.cache.maxSize=1 in src/test/resources/spring.properties (https://docs.spring.io/spring/docs/current/spring-framework-reference/testing.html#testcontext-ctx-management-caching)
Spring-Boot: 2.5.4
Using #DirtiesContext is our last resource.
Note: Use a random port
Either:
Passing as annotation property: #AutoConfigureWireMock(port = 0).
Note: Keep in mind that default port is 8080, so could be a port conflict with local service or others running locally (if server.port has a default value / not specified).
Or in application-test.properties/.yml: wiremock.server.port=0.
I kindly suggest the last one, as it is more maintainable an keep config in one place to be queried.
Can reuse this on multiple endpoints (third party or local services):
app:
endpoints:
local-service: http://localhost:${wiremock.server.port}/some/path
external-service: http://localhost:${wiremock.server.port}/another/path
I have a spring-boot application that has to connect to a deployed Apache Apache ActiveMQ Artemis 2.9.0 broker.
The broker has the default configuration listening to the 61616 port.
I've got a library where I have encapsulated the calls to the broker. The pom.xml is as follows:

My configuration file includes the following lines to connect to the artemis broker:

# Spring JMS Settings
jms:
template:
qos-enabled: true
Here I include the method I'm using to send the messages
package com.xxx.ems.microservice.core.queue;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.Session;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.UncategorizedJmsException;
import org.springframework.jms.annotation.EnableJms;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.MessageCreator;
import org.springframework.jms.support.converter.MessageConverter;
import org.springframework.stereotype.Component;
// Apache Artemis Message Sender
#Component
#EnableJms
public class MessageSender {
#Autowired
JmsTemplate jmsTemplate;
#Autowired
MessageConverter defaultMessageConverter;
protected void send(String destinationQueue, EMSFileMessage emsFileMessage, int ... priority) throws EMSQueueException{
try{
if (priority.length == 0){
jmsTemplate.convertAndSend(destinationQueue, emsFileMessage);
}else{
jmsTemplate.setPriority(priority[0]);
jmsTemplate.send(destinationQueue, new MessageCreator() {
#Override
public Message createMessage(Session session) throws JMSException {
return defaultMessageConverter.toMessage(emsFileMessage, session);
}
});
}
}catch(UncategorizedJmsException ex){
throw new EMSQueueException("Fatall error, probably due to connection with message broker, address that is trying to connect with address "+destinationQueue, ex);
}
}
}
Before calling the send message I'm writing a log to check the ArtemisProperties (host and port) and both have the proper values. The destinationQueue has also the correct value.
For some reason I've got the following exception

I have seen another exception with debug level that might be related. It is
Unable to load the library 'netty_transport_native_epoll_x86_64', trying other loading mechanism.
java.lang.UnsatisfiedLinkError: no netty_transport_native_epoll_x86_64 in java.library.path
Is there anything that should be installed? I'm new with artemis and such kind of brokers.
Any help would be appreciated

but only when I'm testing but testing is working so this is not influence testing yet this is unusual , when I do normally run spring application everything is fine
public class CategoryControllerTest {

In line with webTestClient = WebTestClient.bindToController(categoryController).build(); I've got an error

Hibernate Validator also requires an implementation of the Unified Expression Language (JSR 341) for evaluating dynamic expressions in constraint violation messages. In a Java SE environment, you have to add an implementation as dependency to your POM file.
This is an exception from hibernate-validator - the validation library that has (almost) nothing to do with the database connectivity. It's a transitive dependency of some library that you included into your project (you can run mvn dependency:tree to determine which).
Try to add the javax.el-api dependency that the stacktrace error asks for.
If your project depends on Hibernate Validator 5.x:
<dependency>
<groupId>javax.el</groupId>
<artifactId>javax.el-api</artifactId>
<version>2.2.5</version>
</dependency>
Hibernate Validator 6.x:

I am working on Spring Boot + Microservices project. In this project, have developed "microservices-dashboard" project as well.
When I simply run this project, found the below error. I'm using spring-boot-starter-parent to <version>2.0.4.RELEASE</version>
Error:
org.springframework.beans.factory.BeanDefinitionStoreException: Failed to process import candidates for configuration class [com.its.MicroservicesDashboardApplication]; nested exception is java.lang.IllegalStateException: Could not evaluate condition on de.codecentric.boot.admin.config.SpringBootAdminClientAutoConfiguration due to org/springframework/boot/bind/RelaxedPropertyResolver not found. Make sure your own configuration does not rely on that class. This can also happen if you are #ComponentScanning a springframework package (e.g. if you put a #ComponentScan in the default package by mistake)

Like Simon Martinelli already said, the microservices dashboard is not compatible with Spring Boot 2.
We are aware of this issue and already did some research on the matter.
Because most of us are not working at a company which has its main focus on open source, we are forced to work on this project during our free time.
Unfortunately due to passed and recent events this project didn't receive the work/love it deserves to have.
However, it still is our intention to continue the work on this project.
microservices-dashboard-server is not compatible with Spring Boot 2
And as I see the last commit is older than a year I assume that this is no longer developed.
