I have a fairly simple Spring Boot application which exposes a small REST API and retrieves data from an instance of MongoDB. Queries to the MongoDB instance go through a Spring Data based repository. Some key bits of code below.
// 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);
}
}
So the idea here is to have the integration tests (empty at the moment) connect to the embedded mongo instance and not the "live" one. However, it doesn't work. I can see the tests connecting to the "live" instance of Mongo, and if I shut that down the build simply fails as it is still attempting to connect to the live instance of Mongo. Does anyone know why this is? How do I get the tests to connect to the embedded instance?
