我需要模拟假客户端，我尝试使用Wiremock，例如如何使用spring-cloud-netflix和假装编写集成测试
但是，我在调用stubFor时收到以下错误

这是MyIntegrationTest.java的代码
@RunWith(SpringRunner.class)
@SpringBootTest(
classes = {MyAppTests.class, com.example.app.ContextConfiguration.class},
properties = {"feign.hystrix.enabled=true"}
)
@EnableAutoConfiguration
@ContextConfiguration(classes = {MyIntegrityTest.LocalRibbonClientConfiguration.class})
public class MyIntegrityTest {
@ClassRule
public static WireMockClassRule wiremock = new WireMockClassRule(
wireMockConfig().dynamicPort());
@Rule public WireMockClassRule instanceRule = wiremock;
@TestConfiguration
public static class LocalRibbonClientConfiguration {
@Bean
public ServerList<Server> ribbonServerList() {
System.out.println("wiremock.port()" + wiremock.port());
return new StaticServerList<>(new Server("localhost", wiremock.port()));
}
}
@Test
public void testOne() {
stubFor(WireMock.post(anyUrl())
.willReturn(aResponse()
.withStatus(HttpStatus.OK.value())
.withHeader("Content-Type", javax.ws.rs.core.MediaType.APPLICATION_JSON)
.withBody("{}")
)
);
}
}
如何解决？
如果stubfor方法导致连接重置，则意味着主机上已在该特定端口上侦听某些内容。您可以看到，在存根期间，它使用HttpAdminClient来检查该端口并向其发出请求。该预检请求会导致该连接重置。
