Spring集成Java DSL：如何在JUnit中运行集成流？

Question

如何在下面的JUnit类中运行integrationFlow？目前出现了例外情况

java.lang.AssertionError: Further request(s) expected leaving 1 unsatisfied expectation(s). 0 request(s) executed.

因为整合流没有启动。

JUnit类：

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@DirtiesContext
public class FlowTest {
private final RestTemplate restTemplate = new RestTemplate();

private MockRestServiceServer mockServer;

@Before
public void setup() {
    mockServer = MockRestServiceServer.createServer(restTemplate);
}

@Test
public void test() {
    mockServer.expect(requestTo("http://localhost:8080/data"));

    final IntegrationFlow integrationFlow = f -> f
            .handle(Http.outboundGateway("http://localhost:8080/data", restTemplate).httpMethod(HttpMethod.GET)
                    .expectedResponseType(String.class));

    mockServer.verify();
}

}

您不能仅仅在测试方法中定义这样的流；框架必须在幕后进行大量组装。

将流定义为测试@Configuration类中的@Bean。
