JUnit Spring Boot Application - Could not autowire fields

I have small app written with JHipster code generator with Spring Boot on back-end.

For my app I'm trying to write some simple unit/integration tests but I have an error:

Could not autowire. No beans of <type> found
. I'm using IntelliJ IDE, latest version. Here is my piece of code:

package com.logate.adminpanel.web.rest;

import com.logate.adminpanel.CrmScoringApp; import
com.logate.adminpanel.repository.CityRepository; import
com.logate.adminpanel.service.CityService; import org.junit.Test;
import org.junit.runner.RunWith; import
org.springframework.boot.test.SpringApplicationConfiguration; import
org.springframework.test.context.ContextConfiguration; import
org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;
import org.springframework.transaction.annotation.Transactional;
import org.springframework.util.Assert;

import javax.inject.Inject;

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = CrmScoringApp.class)
@WebAppConfiguration
public class CityRestTest {

@Inject
private CityService cityService;

@Inject
private CityRepository cityRepository;

@Test
public void test()
{
Assert.isNull(null);
}
}


I can't figure it out what is the problem here.

Here is my boot application class:

package com.logate.adminpanel;

import com.logate.adminpanel.config.Constants;
import com.logate.adminpanel.config.JHipsterProperties;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

@EnableConfigurationProperties({ JHipsterProperties.class, LiquibaseProperties.class })
public class CrmScoringApp {

private static final Logger log = LoggerFactory.getLogger(CrmScoringApp.class);

@Inject
private Environment env;

/**
* Main method, used to run the application.
*
* @param args the command line arguments
* @throws UnknownHostException if the local host name could not be resolved into an address
*/
public static void main(String[] args) throws UnknownHostException {
SpringApplication app = new SpringApplication(CrmScoringApp.class);
SimpleCommandLinePropertySource source = new SimpleCommandLinePropertySource(args);
addDefaultProfile(app, source);
Environment env = app.run(args).getEnvironment();
log.info("\n----------------------------------------------------------\n\t" +

}

/**

*/
private static void addDefaultProfile(SpringApplication app, SimpleCommandLinePropertySource source) {
if (!source.containsProperty("spring.profiles.active") &&
!System.getenv().containsKey("SPRING_PROFILES_ACTIVE")) {

app.setAdditionalProfiles(Constants.SPRING_PROFILE_DEVELOPMENT);
}
}

/**

@PostConstruct
public void initApplication() {
if (env.getActiveProfiles().length == 0) {
log.warn("No Spring profile configured, running with default configuration");
} else {
log.info("Running with Spring profile(s) : {}", Arrays.toString(env.getActiveProfiles()));
Collection<String> activeProfiles = Arrays.asList(env.getActiveProfiles());
if (activeProfiles.contains(Constants.SPRING_PROFILE_DEVELOPMENT) && activeProfiles.contains(Constants.SPRING_PROFILE_PRODUCTION)) {
log.error("You have misconfigured your application! " +
"It should not run with both the 'dev' and 'prod' profiles at the same time.");
}
if (activeProfiles.contains(Constants.SPRING_PROFILE_DEVELOPMENT) && activeProfiles.contains(Constants.SPRING_PROFILE_CLOUD)) {
log.error("You have misconfigured your application! " +
"It should not run with both the 'dev' and 'cloud' profiles at the same time.");
}
}
}
}


Here is city repository class:

package com.logate.adminpanel.repository;

import com.logate.adminpanel.domain.City;
import org.springframework.data.jpa.repository.JpaRepository;

/**
* Spring Data JPA repository for the City entity.
*/
public interface CityRepository extends JpaRepository<City,Long> {

}


and here is city service class:

package com.logate.adminpanel.service;

import com.logate.adminpanel.domain.City;
import com.logate.adminpanel.repository.CityRepository;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.Pageable;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import javax.inject.Inject;

/**
* Service Implementation for managing City.
*/
@Service
@Transactional
public class CityService {

private final Logger log = LoggerFactory.getLogger(CityService.class);

@Inject
private CityRepository cityRepository;

/**
* Save a city.
*
* @param city the entity to save
* @return the persisted entity
*/
public City save(City city) {
log.debug("Request to save City : {}", city);
City result = cityRepository.save(city);

return result;
}


@Transactional(readOnly = true)
public Page<City> findAll(Pageable pageable) {
log.debug("Request to get all Cities");
Page<City> result = cityRepository.findAll(pageable);
return result;
}

@Transactional(readOnly = true)
public City findOne(Long id) {
log.debug("Request to get City : {}", id);
City city = cityRepository.findOne(id);
return city;
}

public void delete(Long id) {
log.debug("Request to delete City : {}", id);
cityRepository.delete(id);
}
}

Does anyone have an idea? Thank you in advance.

Answer

Your exception is caused by: java.lang.IllegalStateException: Tomcat connector in failed state. Usually it occurs when port used by tomcat is already in use. Try to change server.port in src/test/resources/config/application.yml file
