java - TestContainers、Couchbase 和 Spring Boot - ScheduledFutureTask 被 ScheduledThreadPoolExecutor 拒绝

Question

我们正在为我们的 Spring Boot 2.1.7.RELEASE 和 Couchbase 数据库创建集成测试。

我们正在使用 testcontainers当测试运行完成时我们得到这个错误:

java.util.concurrent.RejectedExecutionException: Task java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask@da0432 rejected from java.util.concurrent.ScheduledThreadPoolExecutor@238be2[Terminated, pool size = 0, active threads = 0, queued tasks = 0, completed tasks = 0]

---

在我们的 pom 中:

    <dependency>
        <groupId>org.testcontainers</groupId>
        <artifactId>couchbase</artifactId>
        <version>1.12.1</version>
        <scope>test</scope>
    </dependency>

    <dependency>
        <groupId>org.testcontainers</groupId>
        <artifactId>testcontainers</artifactId>
        <version>1.12.1</version>
        <scope>test</scope>
    </dependency>

在我们的“集成测试配置”类中:

@RunWith(SpringRunner.class)
@SpringBootTest(classes = {MyApplication.class, IntegrationTestConfig.CouchbaseTestConfig.class},
    webEnvironment = SpringBootTest.WebEnvironment.DEFINED_PORT)
public abstract class IntegrationTestConfig{

@ClassRule
public static CouchbaseContainer couchbaseContainer = new CouchbaseContainer()
        .withIndex(true)
        .withQuery(true)
        .withClusterAdmin("clusterUser", "clusterPassword")
        .withNewBucket(DefaultBucketSettings.builder()
                .enableFlush(true)
                .name("bucketName")
                .password("bucketPassword")
                .quota(100)
                .replicas(0)
                .type(BucketType.COUCHBASE)
                .build());

@BeforeClass
public static void beforeClass() throws IOException{
    log.debug("Starting containers...");
    couchbaseContainer.start();
}

@AfterClass
public static void afterClass(){
    log.debug("Stopping containers...");
    couchbaseContainer.stop();
}

在我们的 IntegrationTest 类中:

public class MyIntegrationTest extends IntegrationTestConfig{

@LocalServerPort
private int port;

@Test
public void testSomething(){
   ....
}

当尝试运行集成测试时，我们在控制台中看到:

    ℹ︎ Checking the system...
    ✔ Docker version should be at least 1.6.0
    ✔ Docker environment should have more than 2GB free disk space

然后我们在控制台中得到这个一两秒钟:

DEBUG [IntegrationTestConfig] - Starting containers... 
DEBUG [IntegrationTestConfig] - Stopping containers... 

然后我们得到这个错误:

您可能需要以守护进程模式运行您的数据库，这样它就不会自动停止:https://www.testcontainers.org/modules/databases/#running-container-in-daemon-mode
