mockmvc_NULL123

我有一个spring集成测试，通过以下方式配置嵌入式mongo db数据库：

@WebAppConfiguration
@ContextConfiguration(classes = TpimApplication.class)
//@SpringBootTest(classes=SPApplication.class)
//@WebMvcTest(controllers = {ControllerA.class, ControllerB.class})
@AutoConfigureMockMvc
@DataMongoTest
public class IntegrationUnitTests {

    private static final String CONNECTION_STRING = "mongodb://%s:%d";

    private static MongodExecutable mongodExecutable;
    private static MongoTemplate mongoTemplate;

//    @Autowired
    private WebApplicationContext context;
    @Autowired
    private MockMvc mockMvc;

    @BeforeAll
    static void setup() throws Exception {
        String ip = "localhost";
        int port = 65535;

        IMongodConfig mongodConfig = new MongodConfigBuilder().version(Version.Main.PRODUCTION)
            .net(new Net(ip, port, Network.localhostIsIPv6()))
            .build();

        MongodStarter starter = MongodStarter.getDefaultInstance();
        mongodExecutable = starter.prepare(mongodConfig);
        mongodExecutable.start();
        mongoTemplate = new MongoTemplate(MongoClients.create(String.format(CONNECTION_STRING, ip, port)), "TestDB");

        Resource resource = new ClassPathResource("mocked_data/test_data.json");
        setupData(resource, "test_collection");

    }

@Test
    void test() throws Exception {
        MockHttpServletRequestBuilder requestBuilder = MockMvcRequestBuilders.get("/endpoint")
                .header("header1", "api-key")
                .header("Content-Type", "application/json");

        this.mockMvc.perform(requestBuilder).andExpect(status().isOk());
    }

每当我运行测试时，我得到：

是什么导致了 mockMvc 不在这里注射？
我甚至有 @AutoConfigureMockMvc 出席。
出什么问题了？

好的，我用下面的代码让它工作。

@AutoConfigureMockMvc
@AutoConfigureDataMongo
@SpringBootTest
public class FirstControllerIT {

    @Autowired
    private MockMvc mockMvc;

    @Autowired
    private FirstController controller;

}

看起来您不能同时使用@springboottest和@datamongotest。对于@autoconfiguremockmvc，它需要spring上下文。
如果您不想使用@springboottest，您仍然可以使用下面的代码使用standalone（没有@autowired/spring context）安装mockmvc。

mockMvc = MockMvcBuilders.standaloneSetup(controller).build();

========================================编辑：演示嵌入式数据库的使用==

@AutoConfigureMockMvc
@AutoConfigureDataMongo
@SpringBootTest
public class FirstControllerIT {

    @Autowired
    private MockMvc mockMvc;

    @Autowired
    private FirstController controller;

    private static final String CONNECTION_STRING = "mongodb://%s:%d";

    private MongodExecutable mongodExecutable;
    private MongoTemplate mongoTemplate;

    @AfterEach
    void clean() {
        mongodExecutable.stop();
    }

    @BeforeEach
    void setup() throws Exception {
        String ip = "localhost";
        int port = 27017;

        IMongodConfig mongodConfig = new MongodConfigBuilder().version(Version.Main.PRODUCTION)
            .net(new Net(ip, port, Network.localhostIsIPv6()))
            .build();

        MongodStarter starter = MongodStarter.getDefaultInstance();
        mongodExecutable = starter.prepare(mongodConfig);
        mongodExecutable.start();
        mongoTemplate = new MongoTemplate(MongoClients.create(String.format(CONNECTION_STRING, ip, port)), "test");
    }

    @Test
    void test() throws Exception {
        // given
        DBObject objectToSave = BasicDBObjectBuilder.start()
            .add("key", "value")
            .get();

        // when
        mongoTemplate.save(objectToSave, "collection");

    }

}

如果在依赖项中嵌入了mongodb，那么spring将自动连接所有内容，包括存储库中的mongotemplate。
