Spring 集成 Java DSL:如何 运行 JUnit 中的集成流程?

Spring Integration Java DSL: How to run the integration flow in the JUnit?

如何运行下面JUnit中的integrationFlow class?目前出现异常

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

因为集成流程没有启动。

JUnit class:

@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();
}

}

您不能只在测试方法中定义这样的流程;该框架必须在幕后进行大量组装。

在测试中将流定义为 @Bean @Configuration class。
