java - JUnit Spring Boot 应用程序 - 无法 Autowiring 字段

Question

我有一个用 JHipster 代码生成器编写的小应用程序，后端带有 Spring Boot。

对于我的应用程序，我正在尝试编写一些简单的单元/集成测试，但出现错误:Could not autowire. No beans of <type> found 。我正在使用 IntelliJ IDE，最新版本。这是我的代码:

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);
     }
 }

我不知道这里出了什么问题。

这是我的启动应用程序类:

package com.logate.adminpanel;

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

@ComponentScan
@EnableAutoConfiguration(exclude = {    MetricFilterAutoConfiguration.class, MetricRepositoryAutoConfiguration.class })
@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" +
            "Application '{}' is running! Access URLs:\n\t" +

            "External: \thttp://{}:{}\n----------------------------------------------------------",
        env.getProperty("spring.application.name"),
        env.getProperty("server.port"),
        InetAddress.getLocalHost().getHostAddress(),
        env.getProperty("server.port"));
}

/**

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.");
             }
        }
    }
}

这是城市存储库类:

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> {

}

这是城市服务等级:

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
@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);
    }
}

有人有想法吗？先感谢您。

您的异常是由以下原因引起的:java.lang.IllegalStateException:Tomcat 连接器处于失败状态。通常当tomcat使用的端口已被使用时会发生这种情况。尝试更改 src/test/resources/config/application.yml 文件中的 server.port
