无法在Spring Boot中运行任何单元测试

127

Ryan S：

我正在尝试编写一个简单的单元测试。这个测试函数将调用我的服务，该服务从数据库中获取信息，将其推送到列表中并返回。我在调试日志中查看了很多内容，以查找可能的原因，但是似乎没有什么可以帮助我。我对Spring Boot不太熟悉，但是所有这些努力似乎使我感到惊讶，而且我无法通过简单的单元测试。

错误日志

Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaAutoConfiguration.class]: Invocation of init method failed;

示例测试

import org.springframework.boot.test.context.TestConfiguration;
import org.springframework.boot.test.mock.mockito.MockBean;
import org.springframework.context.annotation.Bean;
import org.springframework.test.context.junit4.SpringRunner;


import java.util.ArrayList;

import static org.assertj.core.api.Assertions.assertThat;

@RunWith(SpringRunner.class)
@TestConfiguration
@SpringBootTest(classes = {
        AlgoQApplication.class,
        })
public class ExampleTest extends AlgoQApplicationTests {

    @Autowired
    private AlgorithmService aService;

    @MockBean
    private SubscriberRepository employeeRepository;

    @Bean
    public AlgorithmService aService() {
        return new AlgorithmService();
    }


    @Test
    public void subscriberListNull() throws Exception {
        ArrayList<Subscriber> subs = aService.getSubscribers();
        assertThat(subs).isEmpty();
    }

}

服务

package com.algoq.algoq.services;

import com.algoq.algoq.models.Subscriber;
import com.algoq.algoq.respositories.SubscriberRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.stereotype.Service;

import java.lang.reflect.Array;
import java.util.ArrayList;
import java.util.List;

@Service
public class AlgorithmService {

    @Autowired
    private SubscriberRepository subRep;

    /**
     * Gets a list of subscribers to return to the API
     * @return
     */
    public ArrayList<Subscriber> getSubscribers() {
        ArrayList<Subscriber> subscribers = new ArrayList<>();
        subRep.findAll()
                .forEach(subscribers::add);
        return subscribers;
    }

    /**
     * Adds a new subscriber to the database
     * @param sub
     * @return
     */
    public void addSubscriber(Subscriber sub) {
        subRep.save(sub);
    }

    /**
     * Finds a single user id
     * @param email
     * @return
     */
    public List<Subscriber> getSubscriber(String email) {
        return subRep.findByEmailAddress(email);
    }
}

应用

package com.algoq.algoq;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;

@SpringBootApplication
//@EnableScheduling
public class AlgoQApplication {

    public static void main(String[] args) {
        SpringApplication.run(AlgoQApplication.class, args);
    }
}

Aliaksei Stadnik：

导致异常的真正原因是

java.lang.ClassNotFoundException: javax.xml.bind.JAXBException

因此，我相信您需要将JAXBE库添加到您的类路径（它已从java9中的JDK中删除，我想您正在使用java9）

尝试将其添加到您的pom文件中

<!-- https://mvnrepository.com/artifact/javax.xml.bind/jaxb-api -->
<dependency>
  <groupId>javax.xml.bind</groupId>
  <artifactId>jaxb-api</artifactId>
  <version>2.3.0</version>
</dependency>
