Spring Integration - placeholders not injected into ws:outbound-gateway uri (only for unit tests)

Question

I wrote some Spring Integration flow which effectively calls some external WebService. ws:outbound-gateway uri of mentioned WS is configured via property placeholders and that works perfectly well when running full application context. Properties are configured in Spring Boot's application.properties .

Now when I try to write an integration test which calls Gateway (BigService) it fails with IllegalArgumentException: Map has no value for 'adapter.icc.big.srv.protocol' . Exception is thrown when calling Gateway method ( BigService#invoke ) So it looks like application.properties are not read but when I inspect Environment in test context everything looks fine.

Please find the most important code snippets bellow.

// part of int-big-conf.xml
<int:chain input-channel="adapter.big.inputChannel" output-channel="adapter.big.outputChannel">
  <int-ws:outbound-gateway  id="bigVerificationGateway"
     uri="${adapter.icc.big.srv.protocol}://${adapter.icc.big.srv.host}:${adapter.icc.big.srv.port}/${adapter.icc.big.srv.context}"
     marshaller="bigMarshaller" unmarshaller="bigMarshaller" />
</int:chain>

// configuration class (full)
@Configuration
@ImportResource("classpath:int/big/int-big-conf.xml")
@ComponentScan("pl.orange.opl.cv.integration.big")
public class BigIntegrationConfiguration {

   @Bean(name = "inputValidator")
   public Validator inputValidator(){
       return new LocalValidatorFactoryBean();
   }
}

@RunWith(SpringJUnit4ClassRunner.class)
@EnableAutoConfiguration
@SpringApplicationConfiguration(classes = {BigIntegrationConfiguration.class})
public class BigTest {

    @Autowired
    private BigService bigService;

    @Test
    public void testVerificationNegative() throws IOException {
        ....
        BIGIntegrationResponseDTO invoke = bigService.invoke(bigRequestDTO);
        ....
    }

Technology stack: - Spring Boot 1.3.0 - Spring Integration 4.2.1 - Spring 4.2.3

Any idea what I am doing wrong? Thanks in advance

Answer 1

You should use @IntegrationTest alongside with the @SpringApplicationConfiguration :

* Test class annotation signifying that the tests are "integration tests" and therefore
 * require full startup in the same way as a production application. Normally used in
 * conjunction with {@code @SpringApplicationConfiguration}.
 * <p>
 * If your test also uses {@code @WebAppConfiguration} consider using the
 * {@link WebIntegrationTest} instead.

The @EnableAutoConfiguration should not be presented there at all. It is responsibility of your tarter BigIntegrationConfiguration .

And yes, we don't see any property placeholders in your configuration.

UPDATE

That is why I have added @EnableAutoConfiguration on BigTest but it simply does not work.

Yes, that's true: it doesn't. And it is just because the test class isn't a bean in the application context DependencyInjectionTestExecutionListener :

protected void injectDependencies(final TestContext testContext) throws Exception {
    Object bean = testContext.getTestInstance();
    AutowireCapableBeanFactory beanFactory = testContext.getApplicationContext().getAutowireCapableBeanFactory();
    beanFactory.autowireBeanProperties(bean, AutowireCapableBeanFactory.AUTOWIRE_NO, false);
    beanFactory.initializeBean(bean, testContext.getTestClass().getName());
    testContext.removeAttribute(REINJECT_DEPENDENCIES_ATTRIBUTE);
}

As you see testInstance isn't registered as a bean, although it is affected by the autowiring mechanism.

To achieve your part/module of bigger application requirements and still have @EnableAutoConfiguration / @SpringBootApplication you should just have some fake internal @Configuration for the test and @Import your partial main config:

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = ContextConfiguration.class)
@DirtiesContext
public abstract class MyTests {

    @SpringBootApplication
    @Import(BigIntegrationConfiguration.class)
    public static class ContextConfiguration {

    }

}
