我一直在尝试按照以下链接中的说明尝试添加自动配置的嵌入式MongoDB实例以进行Cucumber集成测试。这是目前无法正常工作，因为我不断获得一个null MongoTemplate。我以为@DataMongoTest会自动配置“@Autowired private MongoTemplate mongoTemplate;”这不是这种情况吗？以下是我的代码：
mongoTemplate.save（doc，collection）;抛出一个nullpointer异常。
@SpringBootTest(classes = AppCommentApiApplication.class, webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@DataMongoTest
public abstract class SpringIntegrationTest {
@Value("${local.server.port}")
public int port;
@Autowired
private MongoTemplate mongoTemplate;
protected void importJSON(String collection, String file) {
try {
for (String line : FileUtils.readLines(new File(file), "utf8")) {
Document doc = Document.parse(line);
mongoTemplate.save(doc, collection);
}
} catch (IOException e) {
throw new RuntimeException("Could not import file: " + file, e);
}
}
}
@RunWith(Cucumber.class)
@CucumberOptions(format = "pretty",
features = "src/test/resources/features",
glue = "com.app.comment.cucumber")
public class CucumberIntegrationTest {
}
public class StepDefinitions extends SpringIntegrationTest {
private Map<String, String> headerMap = null;
private String postBody = null;
private String putBody = null;
private String formData = null;
private Response response = null;
private String data = null;
private final static String MONGODB_COLLECTION = "comment";
private final static String MONGODB_DATA = "src/test/resources/mongodb-data/data.txt";
@Before
public void setup() {
importJSON(MONGODB_COLLECTION, MONGODB_DATA);
}
@Given("^the header information$")
public void the_header_information(Map<String, String> headerMap) throws Throwable {
this.headerMap = headerMap;
}
@Given("^post message body \"(.*?)\"$")
public void post_message_body(String postBody) throws Throwable {
this.postBody = postBody;
}
@Given("^put message body \"(.*?)\"$")
public void put_message_body(String putBody) throws Throwable {
this.putBody = putBody;
}
}

如果使用JUnit 4，则应该有RunWith(SpringRunner.class)。不需要JUnit 5。
此外，@SpringBootTest无法与@DataMongoTest共存，因为它们用于应用程序的不同部分，而后者仅用于数据部分，而前者用于应用程序部分。 （实际上，如果将两者@BootstrapWith冲突，则无法开始测试）
@DataMongoTest将使用嵌入式数据库，除了@Autowired mongotemplate之外，您无需执行其他配置。如果要使用真实的数据库，请执行以下操作：
@DataMongoTest(excludeAutoConfiguration = EmbeddedMongoAutoConfiguration.class)
我的测试就是这样，并且有效：
@ActiveProfiles("db")
@DataMongoTest
class CouponTypeRefRepositoryTest {
@Autowired
private CouponTypeRefRepository repository; // a simple repository extending `DataMongoRepository`
@Autowired
private MongoTemplate mongoTemplate;
@BeforeEach
void prepare() {
CouponTypeRef toSave = CouponTypeRef.builder()
.id((short)1)
.duration((short)1)
.couponType("COMMERCIAL")
.couponTypeRefConfig(CouponTypeRefConfig.REFUNDABLE_NORMAL)
.build();
mongoTemplate.save(toSave, "CouponTypeRef");
}
@Test
void shouldReturnCouponTypeRef() {
Optional<CouponTypeRef> optional = repository.findById((short)1);
assertThat(optional.isPresent(), is(true));
assertThat(optional.get().getCouponType(), is("COMMERCIAL"));
assertThat(optional.get().getDuration(), is((short)1));
assertThat(optional.get().getCouponTypeRefConfig(), is(CouponTypeRefConfig.REFUNDABLE_NORMAL));
}
我的依赖项是：
implementation 'org.springframework.boot:spring-boot-starter-data-mongodb-reactive:2.2.1.RELEASE'
db个人资料配置：
spring:
data:
mongodb:
host: localhost
port: 27017
database: app1

你有没有能够解决你的问题？ 我无法让Spring Boot在一些随机端口上启动嵌入式MongoDb实例，并且在该测试中更多地连接到该随机端口。
答案 2 :(得分：0)
向@RunWith(SpringRunner.class)类添加SpringIntegrationTest注释应该可行。 SpringRunner将使Bean自动装配到您的测试类中。
