java UncategorizedMongoDbException：命令失败，出现错误10107(NotMaster)：服务器上的“非主”

我在执行MongoDB事务特性的集成测试用例时遇到以下异常。

org.springframework.data.mongodb.UncategorizedMongoDbException: Command failed with error 10107 (NotMaster): 'not master' on server localhost:60876.

我的测试类有以下方法。

@Test
   @Order(1)
   void testUpdateValidationsById() {
       MyEntity entity = new MyEntity();
       entity.setId("6030a6e1b32d1f70b4ce8039");
       entity.setAttributeType("IP Address, FQDN");
       entity.setCategory("NTP");
       entity.setCategoryLabel("NTP");
       entity.setTrueMsgDetails("It is true");
       entity.setFalseMsgDetails("It is false");
       entity.setCorevalidation("Core Validation");

       ResponseEntity<?> re = controller.updateValidationsById(entity);
       boolean flag = re.getStatusCode().is2xxSuccessful();
       assertEquals(true, flag);
   }

我的测试配置类看起来像这样。

@Profile("test")
@ActiveProfiles("test")
@TestConfiguration
public class TestMongoDBConfig implements InitializingBean, DisposableBean {

    private MongodExecutable executable;
    private String replicaSetName = "rs0";
    private int mongoDBPort = 27021;

    @Override
    public void afterPropertiesSet() throws Exception {
        mongoDBPort = Network.getFreeServerPort();
        IMongoCmdOptions cmdOptions = new MongoCmdOptionsBuilder().useNoPrealloc(false).useSmallFiles(false)
                .master(false).verbose(false).useNoJournal(false).syncDelay(0).build();

//      IMongodConfig mongodConfig = new MongodConfigBuilder().version(Version.Main.PRODUCTION)
        IMongodConfig mongodConfig = new MongodConfigBuilder().version(Version.Main.V4_0)
//              .net(new Net(27023, Network.localhostIsIPv6()))
                .net(new Net(mongoDBPort, Network.localhostIsIPv6()))
                .replication(new Storage(null, replicaSetName, 5000)).configServer(true).cmdOptions(cmdOptions)
                .build();

        MongodStarter starter = MongodStarter.getDefaultInstance();
        executable = starter.prepare(mongodConfig);
        executable.start();
    }

    
    @Bean(name = "test1")
    public MongoClient mongoClient() {
        ConnectionString cs = new ConnectionString("mongodb://localhost:" + mongoDBPort + "/");
        MongoClient mongoClient = MongoClients.create(cs);
        System.out.println("--------------------------------------");
        System.out.println("Mongo Selected ort : " + mongoDBPort);
        System.out.println("MongoClient : " + mongoClient);
        System.out.println("--------------------------------------");
        mongoClient.getDatabase("admin").runCommand(new Document("replSetInitiate", new Document()));
        return mongoClient;
    }

    /**
     * Destroy.
     *
     * @throws Exception the exception
     */
    @Override
    public void destroy() throws Exception {
        executable.stop();
    }
}

由于没有解决方案，我将发布我的解决方案，请记住，这种情况发生在嵌入式mongo db（flapdoodle版本3.0.0），只有副本集和以下java & spring mongo驱动程序：

<dependency>
            <groupId>org.springframework.data</groupId>
            <artifactId>spring-data-mongodb</artifactId>
            <version>2.2.13.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.mongodb</groupId>
            <artifactId>mongo-java-driver</artifactId>
            <version>3.11.3</version>
        </dependency>

我们使用的解决方案是以下忙碌等待：

private void waitUntilReplicaReady() throws InterruptedException {
        Document document = getRaplicaStatus();
        while (isReplicaInitializing(document)) {
            document = getRaplicaStatus();
            TimeUnit.MILLISECONDS.sleep(100);
        }
    }

    private boolean isReplicaInitializing(Document document) {
        return document.get("lastStableCheckpointTimestamp", BsonTimestamp.class).getTime() == 0;
    }

    private Document getRaplicaStatus() {
        return getDatabase("admin").runCommand(new BasicDBObject("replSetGetStatus", "1"));
    }

当没有设置lastStableCheckpointTimestamp时间时，我们保持池化，当设置了lastStableCheckpointTimestamp时，我们允许程序前进（填充需要大约2秒）
