我是Spring Integration的新手，我正在尝试测试该频道。 我写了下面的代码。但是我在测试时遇到异常。请帮助我解决这个问题。
Spring集成流程。
<int:channel id="reqGetAllMedChannel" />
<int:channel id="resGetAllMedChannel" />
<int-http:inbound-gateway
request-channel="reqGetAllMedChannel"
reply-channel="resGetAllMedChannel" supported-methods="GET"
path="/getAllMedicines">
<int-http:request-mapping
consumes="application/json" produces="application/json" />
</int-http:inbound-gateway>
<int:service-activator
ref="medicineServiceActivator" method="getAllMedicines"
input-channel="reqGetAllMedChannel"
output-channel="resGetAllMedChannel" />
正在被调用的方法。
public Message<List<Medicine>> getAllMedicines() {
log.info("GET request for Medicine");
List<Medicine> medLst = medicineService.getAllMedicines();
return MessageBuilder.withPayload(medLst).setHeader("http_statusCode", HttpStatus.OK).build();
}
测试xml配置
<import resource="classpath:medicineIntegration.xml"/>
<int:bridge input-channel="resGetAllMedChannel" output-channel="testOutput">
</int:bridge>
<int:channel id="testOutput">
<int:queue/>
</int:channel>
jUnit测试用例。
@RunWith(SpringRunner.class)
@SpringBootTest
@ContextConfiguration(locations= {"classpath*:Integration-Test.xml"})
public class MessageChannelTest {
@Autowired
private MessageChannel inputChannel;
@Autowired
private QueueChannel testChannel;
@Mock
private MedicineService medicineService;
@Test
public void testChannel() {
List<Medicine> medicines = new ArrayList<Medicine>();
Medicine medicine1 = new Medicine();
medicine1.setMedName("Crocine");
medicine1.setExpDate("01-01-2020");
Medicine medicine2 = new Medicine();
medicine2.setMedName("Paracetamole");
medicine2.setExpDate("02-02-2020");
medicines.add(medicine1);
medicines.add(medicine2);
when(medicineService.getAllMedicines()).thenReturn(medicines);
inputChannel.send(MessageBuilder.withPayload("").build());
Message<?> outMsg = testChannel.receive(1000);
assertThat(medicineService).isEqualTo(outMsg.getPayload());
}
}
以下是我在测试jUnit代码时遇到的异常。请帮助我，让我知道我做错了什么。

答案 0 :(得分：1)
根据例外情况，您的olMailItem取决于medicineService。由于您只有一个：
MedicineRepository您不会影响应用程序上下文，也不会替换您的@Mock
private MedicineService medicineService;
bean定义。
如果您真的只想模拟medicineService并在应用程序上下文中替换它，则应考虑使用Spring Boot中的MedicineService：https://docs.spring.io/spring-boot/docs/2.1.1.RELEASE/reference/htmlsingle/#boot-features-testing-spring-boot-applications-mocking-beans
对于该@MockBean，您也可以@MockBean，而您的MedicineRepository在应用程序上下文中将保持不变。
在其他问题中，我已经向您建议过类似的内容：JUnit for Spring Integration Activator with return type Message<?>
答案 1 :(得分：0)
MedicineRepository是模拟服务的一部分，请尝试使用@Spy和@Autowired将其添加到测试上下文中：
@Autowired
@Spy
MedicineRepository medicineRepository
