Spring引导嵌入式MongoDB在构建过程中不起作用

Question

我在测试中使用嵌入式Mongodb，所有MongoRepository测试都运行良好。但是，只有当我使用IDE在测试类中逐个或全部运行服务测试，并且在构建过程中不起作用时，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);
} 
.....

依赖项：

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");

如下面的代码片段所示。

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);
}
}
