如何在Spring Boot 2.2集成测试中使用嵌入式MongoDB

Question

我想使用嵌入式MongoDB实例，而不是连接到我的localhost MongoDB。

在集成测试中，我只使用mockMvc。我的测试类上的注释

@Profile("it")
@SpringBootTest
//@DataMongoTest - tried to do with that and can't run app because of missing Security beans.
@AutoConfigureMockMvc
@ExtendWith(SpringExtension.class)
public class ControllerIntegrationTest {
@Autowired
private WebApplicationContext context;
@Autowired
private MockMvc mockMvc;
...
}

MongoDB配置

@Configuration
@EnableMongoRepositories
public class MongodbConfiguration {
@Value("${mongo.db.url:mongodb://127.0.0.1}")
private String MONGO_DB_URL;
@Value(("${mongo.db.port:27017}"))
private int MONGO_DB_PORT;
@Value("${mongo.db.name:admin}")
private String MONGO_DB_NAME;
@Bean
public MongoClient mongo() {
return MongoClients.create(MONGO_DB_URL + ":" + MONGO_DB_PORT);
}
@Bean
public MongoDbFactory mongoDbFactory(MongoClient mongoClient) {
return new SimpleMongoClientDbFactory(mongoClient, MONGO_DB_NAME);
}
@Bean
public WriteConcernResolver writeConcernResolver() {
return action -> {
System.out.println("Using Write Concern of MAJORITY");
return WriteConcern.MAJORITY;
};
}
@Bean
public MongoCustomConversions customConversions(OffsetDateTimeReadConverter offsetDateTimeReadConverter,
OffsetDateTimeWriteConverter offsetDateTimeWriteConverter) {
return new MongoCustomConversions(asList(offsetDateTimeReadConverter, offsetDateTimeWriteConverter));
}
}

我有"；de.flapdoodle.embed:de.flaptoodle.eembed.mongo:2.2.0"在我的build.gradle文件中：

testImplementation "org.springframework.boot:spring-boot-starter-test"
testImplementation "org.mockito:mockito-core:2.23.4"
testImplementation "org.assertj:assertj-core:3.16.1"
integrationTest "de.flapdoodle.embed:de.flapdoodle.embed.mongo:2.2.0"

我正试图做到这一点，正如《如何让junit测试在springboot应用程序中使用嵌入式mongoDB？》中所述？，然而它是从2018年开始的，所以它可能已经过时了。

每当我运行测试时，它仍然会尝试连接到localhost MongoDB实例，而不是运行嵌入式。

鉴于这是一个it，我建议您使用MongoDB容器来运行测试，它将为您提供关于应用程序的更精确的见解，并且可以与CI/CD管道集成。
