如何配置嵌入式 MongDB 以在 Spring Boot 应用程序中进行集成测试？

我有一个相当简单的Spring Boot应用程序，它公开了一个小的REST API，并从MongoDB的实例中检索数据。对MongoDB实例的查询通过基于Spring Data的存储库。下面的一些关键代码位。
// Main application class
@EnableAutoConfiguration(exclude={MongoAutoConfiguration.class, MongoDataAutoConfiguration.class})
@ComponentScan
@Import(MongoConfig.class)
public class ProductApplication {
public static void main(String[] args) {
SpringApplication.run(ProductApplication.class, args);
}
}
// Product repository with Spring data
public interface ProductRepository extends MongoRepository<Product, String> {
Page<Product> findAll(Pageable pageable);
Optional<Product> findByLineNumber(String lineNumber);
}
// Configuration for "live" connections
@Configuration
public class MongoConfig {
@Value("${product.mongo.host}")
private String mongoHost;
@Value("${product.mongo.port}")
private String mongoPort;
@Value("${product.mongo.database}")
private String mongoDatabase;
@Bean(name="mongoClient")
public MongoClient mongoClient() throws IOException {
return new MongoClient(mongoHost, Integer.parseInt(mongoPort));
}
@Autowired
@Bean(name="mongoDbFactory")
public MongoDbFactory mongoDbFactory(MongoClient mongoClient) {
return new SimpleMongoDbFactory(mongoClient, mongoDatabase);
}
@Autowired
@Bean(name="mongoTemplate")
public MongoTemplate mongoTemplate(MongoClient mongoClient) {
return new MongoTemplate(mongoClient, mongoDatabase);
}
}
@Configuration
@EnableMongoRepositories
public class EmbeddedMongoConfig {
private static final String DB_NAME = "integrationTest";
private static final int DB_PORT = 12345;
private static final String DB_HOST = "localhost";
private static final String DB_COLLECTION = "products";
private MongodExecutable mongodExecutable = null;
@Bean(name="mongoClient")
public MongoClient mongoClient() throws IOException {
// Lots of calls here to de.flapdoodle.embed.mongo code base to
// create an embedded db and insert some JSON data
}
@Autowired
@Bean(name="mongoDbFactory")
public MongoDbFactory mongoDbFactory(MongoClient mongoClient) {
return new SimpleMongoDbFactory(mongoClient, DB_NAME);
}
@Autowired
@Bean(name="mongoTemplate")
public MongoTemplate mongoTemplate(MongoClient mongoClient) {
return new MongoTemplate(mongoClient, DB_NAME);
}
@PreDestroy
public void shutdownEmbeddedMongoDB() {
if (this.mongodExecutable != null) {
this.mongodExecutable.stop();
}
}
}
@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = TestProductApplication.class)
@IntegrationTest
@WebAppConfiguration
public class WtrProductApplicationTests {
@Test
public void contextLoads() {
// Tests empty for now
}
}
@EnableAutoConfiguration(exclude={MongoAutoConfiguration.class, MongoDataAutoConfiguration.class})
@ComponentScan
@Import(EmbeddedMongoConfig.class)
public class TestProductApplication {
public static void main(String[] args) {
SpringApplication.run(TestProductApplication.class, args);
}
}
因此，这里的想法是让集成测试（目前为空）连接到嵌入式mongo实例，而不是“实时”实例。但是，它不起作用。我可以看到连接到Mongo的“实时”实例的测试，如果我关闭它，构建就会失败，因为它仍在尝试连接到Mongo的实时实例。有谁知道这是为什么？如何获取测试以连接到嵌入式实例？
