Springブート2.0.0.M3経由でSpring webfluxを使用するプロジェクトで問題が発生します。Springブート統合テストで「java.lang.IllegalStateException：5000 MILLISECONDSの読み込みをブロックする際のタイムアウト」がスローされる
@RestController
@RequestMapping(value="/internal/note")
@Slf4j
public class NoteController {
@Autowired
NoteRepository noteRepository;
@GetMapping("/request/{id}")
public Mono<Note> getNoteByRequestid(@PathVariable("id") String requestid) {
logger.debug("Requesting note by request id '{}'.", requestid);
return noteRepository.findByRequestid(requestid).doOnSuccess(note ->
logger.debug("Found note '{}'.", note))
.doOnSuccess(response -> logger.debug("Successfully found note by request id '{}'.", requestid));
}
}
コードが正常に動作します：以下は、プロジェクトの依存関係、
dependencies {
compile 'org.springframework.boot:spring-boot-starter-actuator',
'org.springframework.cloud:spring-cloud-starter-config',
'org.springframework.cloud:spring-cloud-sleuth-stream',

integTestCompile configurations.testCompile
integTestCompile sourceSets.test.output

}
私はREST APIを持っている、とのコードは以下の通りですです。 Postmanを使用してAPIを呼び出すと、正しい結果が返されます。
私は統合テストコード以下のように持っている：final String data = "{xxxxx}";//JSON Data
final Note newNote = noteRepository.save(objectMapper.readValue(data, Note.class)).block(Duration.ofSeconds(3));
final String requestid = "5982C7366FF1C55D20CF2B70";
this.webClient.get().uri("/internal/note/request/{id}", requestid).accept(MediaType.APPLICATION_JSON_UTF8)
.exchange().expectStatus().isOk();
しかし、テストでは、以下のように投げるのエラーメッセージが失敗します。
