spring - @DataMongoTest 正在创建一个空的 MongoTemplate

标签 spring mongodb spring-boot spring-data-mongodb spring-boot-test

我一直在尝试按照以下链接中的说明添加自动配置的嵌入式 MongoDB 实例以进行 Cucumber 集成测试。这目前不起作用，因为我一直得到一个空的 MongoTemplate。我以为@DataMongoTest 会自动配置“@Autowired private MongoTemplate mongoTemplate;”不是这样吗？以下是我的代码:

mongoTemplate.save(doc, collection);抛出空指针异常。

@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;
    }
}

最佳答案

如果你使用 JUnit 4，你应该有 RunWith(SpringRunner.class)。不需要 JUnit 5。

并且，@SpringBootTest不能与@DataMongoTest共存，因为它们是针对应用程序的不同部分，后者只针对数据部分，而前者针对应用程序部分。 (其实@BootstrapWith放在一起会冲突，无法启动测试)

@DataMongoTest 将使用嵌入式数据库，除了 @Autowired mongotemplate 之外你不需要做额外的配置。如果你想使用真正的数据库，这样做:

@DataMongoTest(excludeAutoConfiguration = EmbeddedMongoAutoConfiguration.class)

我的测试是这样的，它有效:

@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));
    }

我的依赖是:

implementation 'org.springframework.boot:spring-boot-starter-data-mongodb-reactive:2.2.1.RELEASE'

db 配置文件配置:

spring:
  data:
    mongodb:
      host: localhost
      port: 27017
      database: app1
