Spring Boot 1.5.4：在单元测试中排除配置类

Question

I have a Spring Boot project, version 1.5.4, with a MongoDb configuration class:

@Configuration
public class MongoConfig {

@Value("${spring.data.mongo.client.uri:mongodb://localhost:27017/database}")
private String mongoURI;

@Bean
public MongoDbFactory mongoFactory() throws UnknownHostException{
    return new SimpleMongoDbFactory(new MongoClientURI(mongoURI));
}

@Bean
public MongoTemplate mongoTemplate() throws UnknownHostException, MongoException{
    return new MongoTemplate(mongoFactory());
}
}

In my integration test i want use Embedded Mongo ( https://github.com/flapdoodle-oss/de.flapdoodle.embed.mongo ).

The problem is that the MongoDb configuration class start before the initialitation of Embedded mongo and try to connect to the database, so my test fail. If i remove the MongoConfig class, all test work well.

How can i exclude it only in my test execution?

Answer 1

Exclude the MongoDB autoconfiguration by using below annotation over your test class.

@EnableAutoConfiguration(exclude={MongoAutoConfiguration.class, MongoDataAutoConfiguration.class})

Then in the same path as your test class create a configuration class and define your mongo bean over there. This will get picked up during application start up

**@Configuration
public class MockConfigurations {
@Bean
@Primary
public MongoTemplate getMongoTemplate() {
//define your bean
return mongoTemplate;
}
}**

Please refer the answers here. It has two ways of excluding configurations.

Spring boot: apply @Configuration to certain package only

Update 1:

Alternatively, the most efficient way that I can think of is to use Spring profiles and load the profile for the tests

Define your TestConfiguration class and import it your test class.

@RunWith(SpringRunner.class)
@SpringBootTest
@Import(MyTestConfiguration.class)
public class MyTests {

    @Test
    public void exampleTest() {
        ...
    }

}

Update 2: For EmbeddedMongoAutoConfiguration please refer the detailed answers here.

How do you configure Embedded MongDB for integration testing in a Spring Boot application?

Answer 3

I solved it with this configuration on my test class:

@RunWith(SpringRunner.class)
@ComponentScan({"it.app.server.dal","it.app.server.listener"})
@DataMongoTest() //mongoDB
public class ListenerTests {
   ...
}

The annotation @DataMongoTest() load my Embbedded MongoDb and with @ComponentScan i can just load the services and repositories wich i need in my test.
