我是测试容器的新手，所以我有一个问题。我在Spring/Hibernate上有一个应用程序。我有一个docker-image（h2 testbase）和一个带数据的mysql-base（myTestDb）。我用-p 6161：3306在docker中运行这个映像。在test/resources目录中，我有一个文件application.properties。它包含了下一个

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

我使用了mvn测试-它工作正常。现在我想用Testcontainers运行这些测试。我添加了pom.xml依赖项

<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，它已经过时了。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"));
    }
}

如果我使用mvn测试，我会看到（通过docker ps）container启动了，它启动了两到三次（Map在随机端口上进行，如328 xx），但是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testcontainer需要端口（6161）？如何使用参数，在www.example.com中application.properties?我找不到代码示例，其中使用了自定义图像与数据库。提前感谢

更新添加失败测试的完整结果。

有一些信息。我尝试测试MySqlContainer从here（与我的TestMySql）。当我使用干净的mysql：5.5图像-所有的好。但当我尝试添加一些容器的修改（例如addFixedExposedPort）它不是开始，因为端口已经分配。在情况下，当我从脚本添加数据-它是“无法创建容器”。如果我试图给它我的图像（h2 testbase），再次“无法创建容器”。

看来你有两个问题。

  1. Docker正在随机端口上公开mysql服务器，但您需要一个固定端口。要解决此问题，您可以使用GenericContainer的addFixedExposedPort设置固定端口
public class TestMySQL extends MySQLContainer {

    public TestMySQL(String dockerImageName) {
        super(dockerImageName);
        addFixedExposedPort(6161, MYSQL_PORT);
    }

    @Override
    public String getDriverClassName() {
        return "com.mysql.cj.jdbc.Driver";
    }
}

1.您可能没有数据库test，用户test，密码test作为MySQLContainer中的默认凭据，这导致您得到ContainerLaunchException。使用withDatabaseName、withUsername和withPassword正确配置数据库和用户。

@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")
          .withDatabaseName("myTestDb")
          .withUsername("root")
          .withPassword("admin");

    @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"));
    }
}

更新：

若要打开日志记录，请将以下依赖项添加到pom.xml

<dependency>
        <groupId>ch.qos.logback</groupId>
        <artifactId>logback-classic</artifactId>
        <version>1.2.1</version>
    </dependency>

并使用以下内容创建src/test/resources/logback.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger - %msg%n</pattern>
        </encoder>
    </appender>

    <root level="info">
        <appender-ref ref="STDOUT"/>
    </root>

    <logger name="org.testcontainers" level="DEBUG"/>
</configuration

我也遇到了同样的问题。当从MySQLContainer扩展一个自定义类时，容器似乎启动了多次。在我的例子中，启动了三个mysql容器。当我直接使用MySQLContainer类时，一切都按预期运行。只启动了一个mysql容器。
