我是 Testcontainers 的新手,所以我有一个问题。我在 Spring/Hibernate 上有应用程序。我有 docker-image (h2testbase) 和 mysql-base (myTestDb) 和数据。我使用 -p 6161:3306 在 docker 中运行该图像。在 test/resources 目录中,我有文件 application.properties。它包含下一个
jdbc.driverClassName=com.mysql.cj.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:6161/myTestDb?allowPublicKeyRetrieval=true&useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=Europe/Moscow&&useSSL=false
jdbc.username=root
jdbc.cred=admin
hibernate.dialect=org.hibernate.dialect.MySQLDialect
hibernate.show_sql=true
hibernate.format_sql=true
我使用 mvn test - 它正在工作。现在我想用 Testcontainers 运行这些测试。我在 pom.xml 中添加了依赖
<dependency>
<groupId>org.testcontainers</groupId>
<artifactId>testcontainers</artifactId>
<version>1.9.1</version>
</dependency>
<dependency>
<groupId>org.testcontainers</groupId>
<artifactId>mysql</artifactId>
<version>1.9.1</version>
<scope>test</scope>
</dependency>
我扩展了 MySQLContainer 类
public class TestMySQL extends MySQLContainer {
public TestMySQL() {
super();
}
public TestMySQL(String dockerImageName) {
super(dockerImageName);
}
@Override
public String getDriverClassName() {
return "com.mysql.cj.jdbc.Driver";
}
}
因为 MySQLContainer 使用 com.mysql.jdbc.Driver 并且它已被弃用。我的测试(例如)
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {
HibernateConfiguration.class,
SecurityConfiguration.class,
SecurityInitializer.class,
ViewConfiguration.class,
ViewInitializer.class})
@WebAppConfiguration
public class ControllerServiceJTest {
@ClassRule
public static TestMySQL container
= new TestMySQL("h2testbase");
@Autowired
ControllerService controllerService;
@Test
public void stationPagination() {
Map<String, Object> pag = controllerService.stationPagination(4);
Assert.assertTrue(((List<Station>)pag.get("stations")).size() == 8);
}
@Test
public void trainPagination() {
Map<String, Object> pag = controllerService.trainPagination(1);
Assert.assertTrue(((List<Train>)pag.get("trains")).size() == 20);
}
@Test
public void switchHelper() {
Assert.assertTrue(controllerService.stationSwitchHelper("BLUE").equals(URLs.REDIRECT_DASHSTATION + "/2"));
}
}
我正在撞墙。如果我使用 mvn test,我会(通过 docker ps)看到容器已启动。它开始了两三次(并且映射在随机端口上进行,例如 328xx),但随后 maven 告诉
org.testcontainers.containers.ContainerLaunchException: Container startup failed
Caused by: org.rnorth.ducttape.RetryCountExceededException: Retry limit hit with exception
Caused by: org.testcontainers.containers.ContainerLaunchException: Could not create/start container
Caused by: org.rnorth.ducttape.TimeoutException: org.rnorth.ducttape.TimeoutException: java.util.concurrent.TimeoutException
Caused by: org.rnorth.ducttape.TimeoutException: java.util.concurrent.TimeoutException
Caused by: java.util.concurrent.TimeoutException
我现在该怎么办?如何告诉我的测试容器需要端口(6161)?如何使用 application.properties 中的参数?我找不到将自定义图像与数据库一起使用的代码示例。先感谢您
更新 为失败的测试添加完整结果。

有一些资料。我从这里(使用我的 TestMySql)尝试使用 MySqlContainer 进行测试。当我使用干净的 mysql:5.5 图像时 - 一切都很好。但是当我尝试在容器中添加一些修改(例如 addFixedExposedPort)时,它没有启动,因为端口已经分配。如果我从脚本添加数据 - 它是“无法创建容器”。如果我试图给它我的图像(h2testbase),再次“无法创建容器”。
