spring-boot - 将应用程序类型设置为响应式(Reactive)时无法启动 Spring Boot 集成测试

Question

我有一个通过 Spring boot 2.0.0.M3 使用 Spring Webflux 的应用程序。

应用程序在运行时被设置为REACTIVE类型。

public static void main(String[] args) {
    SpringApplication application = new SpringApplication(AgentApplication.class);
    application.setWebApplicationType(WebApplicationType.REACTIVE);
    application.run(args);
}

如果运行主应用程序，响应式(Reactive)应用程序可以正常工作。但我在 Spring Boot 集成测试中未能启动这个应用程序。

我声明测试如下，

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT,
    properties = {"spring.main.webApplicationType=reactive"})
@ActiveProfiles("integTest")
public class NoteHandlerTest {

@Autowired
private WebTestClient webClient;

@Test
public void testGetNoteNotFound() throws Exception {
    this.webClient.get().uri("/note/request/{id}", "nosuchid").accept(MediaType.APPLICATION_JSON_UTF8)
            .exchange().expectStatus().isOk();
}

}

运行测试用例时出现以下错误，

使用 webflux 运行 spring boot 集成测试是否有任何配置问题？

这不是您的配置属性中的拼写错误吗？

“spring.main.web-application-type=reactive”
