Spring Boot 集成测试抛出错误“java.lang.IllegalStateException：阻塞读取超时 5000 毫秒”

问题描述 投票：0回答：3

该问题发生在我通过 Spring boot 2.0.0.M3 使用 Spring webflux 的项目上。以下是项目的依赖项，

dependencies {
        compile 'org.springframework.boot:spring-boot-starter-actuator',
                'org.springframework.cloud:spring-cloud-starter-config',
                'org.springframework.cloud:spring-cloud-sleuth-stream',
                'org.springframework.cloud:spring-cloud-starter-sleuth',
                'org.springframework.cloud:spring-cloud-starter-stream-rabbit',
                'org.springframework.boot:spring-boot-starter-data-mongodb-reactive',
                'org.springframework.boot:spring-boot-starter-data-redis-reactive',
                'org.springframework.boot:spring-boot-starter-integration',
                "org.springframework.integration:spring-integration-amqp",
                "org.springframework.integration:spring-integration-mongodb",
                'org.springframework.retry:spring-retry',
                'org.springframework.boot:spring-boot-starter-webflux',
                "org.springframework.boot:spring-boot-devtools",
                'com.fasterxml.jackson.datatype:jackson-datatype-joda',
                'joda-time:joda-time:2.9.9',
                'org.javamoney:moneta:1.0',
                'com.squareup.okhttp3:okhttp:3.8.1',
                "net.logstash.logback:logstash-logback-encoder:4.11",
                'org.apache.commons:commons-lang3:3.5'
        compileOnly 'org.projectlombok:lombok:1.16.18'
        testCompile 'org.springframework.boot:spring-boot-starter-test',
                'io.projectreactor:reactor-test',
                'org.apache.qpid:qpid-broker:6.1.2',
                'de.flapdoodle.embed:de.flapdoodle.embed.mongo'

        integTestCompile sourceSets.main.output
        integTestCompile configurations.testCompile
        integTestCompile sourceSets.test.output
        integTestRuntime configurations.testRuntime
    }

我有一个REST API，代码如下：

 @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));
        }
    }

代码运行良好。使用Postman调用API时，返回正确的结果。

我有如下集成测试代码：

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();

但是测试失败，抛出如下错误消息：

对于如何解决这个问题有什么建议吗？

这可能是框架中的一个错误，但考虑到类路径上的内容量，您应该尝试创建一个最小的示例项目来重现该错误，并针对 Spring 框架提出一个问题（https://jira .spring.io).

请求超时默认为5秒。您的测试运行时间是否比这更长？也许当您同时积极使用计算机执行其他任务和流程时？

如果是这样，当您配置 

WebTestClient
时，将 
responseTimeout()
 设置为更高的值，如下所示：

@Autowired
private WebTestClient webTestClient;

@BeforeEach
public void setUp() {
    webTestClient =
        webTestClient
            .mutate()
            .responseTimeout(Duration.ofMillis(30000))
            .build();
}

我也有同样的问题。有消息吗？
