Flapdoodle 嵌入式 Mongo 进程无法启动

Question

我正在尝试在执行单元测试时运行 Embedded Mongo 实例。 我正在使用 flapdoodle 嵌入式 mongo package 来实现这一点，但在尝试开始测试时出现错误。

我的 build.gradle 依赖项：

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-data-mongodb'
    implementation 'org.springframework.boot:spring-boot-starter-oauth2-resource-server'
    implementation 'org.springframework.boot:spring-boot-starter-web'
    compileOnly 'org.projectlombok:lombok'
    annotationProcessor 'org.projectlombok:lombok'
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
    testImplementation 'de.flapdoodle.embed:de.flapdoodle.embed.mongo:3.3.0'
}

和测试文件：

@SpringBootTest
public class UserServiceTest {

    @Autowired
    UserServiceImpl userService;

    @MockBean
    MongoTemplate mongoTemplate;

    @MockBean
    UserRepository userRepository;

    @Test
    public void contextLoads() {
        assertThat(userService).isNotNull();
        assertThat(userRepository).isNotNull();
    }

    public User getUser(String authId) {
        User user = new User();
        user.setAuth0Id(authId);
        user.setUserImage("img");
        user.setEmail("email@mail.com");
        user.setName("User 1");
        user.setId("1");
        return user;
    }

    @Test
    public void findByAuth0IdReturnsCorrectly() {
        String id = "helloIamTheId";
        User user = getUser(id);
        when(userRepository.findByAuth0Id(id)).thenReturn(Optional.of(user));
        assertThat(userService.findByAuth0Id(id)).isEqualTo(Optional.of(user));
    }
}

错误：

我有同样的问题，它似乎与版本 3.3.0 有关。

使用 3.2.8 对我有用：

de.flapdoodle.embed:de.flapdoodle.embed.mongo:3.2.8
