Spring boot Embedded MongoDB 在构建期间无法正常工作

Question

我在测试中使用 Embedded Mongodb，所有 MongoRepository 测试都运行良好。但是，只有当我使用 IDE 在测试类中一个一个或全部运行它们并且在构建期间不工作时，服务测试才能正常工作。

@RunWith(SpringRunner.class)
@SpringBootTest
public class UserServiceTest {

    @Autowired
    private UserService userService;

    @Autowired
    private UserRepository userRepository;

    private User user = new User(.....);

    @Test
    public void findByEmail() {
        // Arrange
        String email = user.getEmail();
        User savedUser = userService.save(user);

        // Act
        Optional<User> optionalUser = userService.findByEmail(email);

        // Assert
        assertThat(optionalUser.isPresent()).isTrue();
        assertThat(optionalUser.get().getEmail()).isEqualTo(email);
        assertThat(optionalUser.get()).isEqualTo(savedUser);
    } 
.....

依赖：

    testCompile 'de.flapdoodle.embed:de.flapdoodle.embed.mongo:2.2.0'

在这里你可以看到我的错误日志：

尝试使用

System.setProperty("os.arch", "x86_64");

如下面代码sn-p所示。

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.mongo.MongoProperties;
import org.springframework.boot.autoconfigure.mongo.embedded.EmbeddedMongoAutoConfiguration;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.Bean;

@SpringBootApplication
public class EmbeddedMongoApplication {

    public static void main(String[] args) {
         System.setProperty("os.arch", "x86_64");
         SpringApplication.run(EmbeddedMongoApplication.class, args);
    }
    
    @Bean
    public EmbeddedMongoAutoConfiguration embeddedMongoAutoConfiguration(MongoProperties mongoProperties) {
        return new EmbeddedMongoAutoConfiguration(mongoProperties);
    }
}
