java - Spring Integration - 占位符未注入(inject) ws :outbound-gateway uri (only for unit tests)

标签 java spring spring-boot spring-integration

我编写了一些 Spring Integration 流程，它有效地调用了一些外部 WebService。提到的 WS 的 ws:outbound-gateway uri 是通过属性占位符配置的，在运行完整的应用程序上下文时效果非常好。属性在 Spring Boot 的 application.properties 中配置。

现在，当我尝试编写调用网关 (BigService) 的集成测试时，它失败并显示 IllegalArgumentException: Map has no value for 'adapter.icc.big.srv.protocol'。调用 Gateway 方法时抛出异常 (BigService#invoke) 所以看起来 application.properties 没有被读取，但是当我在测试上下文中检查 Environment 时，一切看起来都很好。

请在下面找到最重要的代码片段。

// 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);
        ....
    }

最佳答案

您应该将@IntegrationTest与@SpringApplicationConfiguration一起使用:

* 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.

@EnableAutoConfiguration 根本不应该出现在那里。这是您的 BigIntegrationConfiguration 的责任。

是的，我们在您的配置中没有看到任何属性占位符。

更新

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

是的，确实如此:事实并非如此。这只是因为测试类不是应用程序上下文中的 bean 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);
}

如您所见，testInstance 并未注册为 bean，尽管它受到 Autowiring 机制的影响。

为了实现您的更大应用程序的部分/模块要求，并且仍然具有@EnableAutoConfiguration/@SpringBootApplication，您应该只拥有一些假的内部@Configuration 用于测试，@Import 您的部分主配置:

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

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

    }

}
