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

问题描述

我们正在为我们的Spring Boot 2.1.7.RELEASE& CouchbaseDB 创建集成测试。

我们正在使用测试容器，并且在测试完成运行时出现此错误：

java.util.concurrent.RejectedExecutionException：任务 java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask@da0432 从 java.util.concurrent.ScheduledThreadPoolExecutor@238be2 被拒绝 [已终止，池大小 = 0，活动线程 = 0，排队任务 = 0，已完成任务 = 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IntegrationTest班：

public class MyIntegrationTest extends IntegrationTestConfig{

@LocalServerPort
private int port;

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

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它一两秒钟：

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

然后我们得到这个错误：

解决方案

您可能需要在守护程序模式下运行数据库，这样它就不会自动停止：https ://www.testcontainers.org/modules/databases/#running-container-in-daemon-mode
