Unable to connect to Docker container using Testcontainers and JUnit Jupiter

问题

我有一个在Java中使用Jakarta Persistence的简单项目。我正在使用JUnit Jupiter，Testcontainers和JBoss Weld运行测试。

这是一个测试：

@EnableAutoWeld
@Testcontainers
@AddBeanClasses({ CategoryRepository.class, EntityManagerProducer.class })
final class CategoryRepositoryTest {
  public static final String POSTGRES_15_3 = "postgres:15.3-alpine3.18";

  @Container
  private final PostgreSQLContainer<?> container = new PostgreSQLContainer<>(DockerImageName.parse(POSTGRES_15_3));

  @Inject
  private CategoryRepository repository;

  @Test
  void save() {
    repository.save(new Category(1L, "Name", "Description"));
    // ...assertions here
  }
}

我确信容器已启动并通过端口5432公开。默认数据库、用户名和密码都默认为test - 这是我在persistence.xml中使用的设置。

<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="https://jakarta.ee/xml/ns/persistence"
    xsi:schemaLocation="https://jakarta.ee/xml/ns/persistence https://jakarta.ee/xml/ns/persistence/persistence_3_0.xsd"
    version="3.0">
  <persistence-unit name="test">
    ...
    <properties>
      <property name="jakarta.persistence.jdbc.driver" value="org.postgresql.Driver" />
      <property name="jakarta.persistence.jdbc.password" value="test" />
      <property name="jakarta.persistence.jdbc.url" value="jdbc:postgresql://localhost:5432/test" />
      <property name="jakarta.persistence.jdbc.user" value="test" />
      <property name="jakarta.persistence.provider" value="org.eclipse.persistence.jpa.PersistenceProvider" />
      <property name="jakarta.persistence.schema-generation.create-script-source" value="database/schema.sql" />
      <property name="jakarta.persistence.schema-generation.database.action" value="create" />
      <property name="jakarta.persistence.sql-load-script-source" value="database/data.sql" />
      <property name="jakarta.persistence.transactionType" value="RESOURCE_LOCAL" />
    </properties>
  </persistence-unit>
</persistence>

我在Gradle构建脚本中有以下（与此问题相关的）依赖项：

  • runtimeOnly("org.postgresql:postgresql:42.6.0")
  • testImplementation("org.jboss.weld:weld-junit5:4.0.0.Final")
  • testImplementation("org.testcontainers:junit-jupiter:1.18.3")
  • testImplementation("org.testcontainers:postgresql:1.18.3")

...但仍然无法连接到正在运行的Docker容器的测试：

Exception [EclipseLink-4002] (Eclipse Persistence Services - 4.0.2.v202306161219): org.eclipse.persistence.exceptions.DatabaseException
Internal Exception: org.postgresql.util.PSQLException: Connection to localhost:5432 refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections.

Error Code: 0
...

基本上，测试无法访问使用提供的设置运行的`Docker`容器。不确定为什么会发生这种情况，但看起来我可能遗漏了一些明显的内容。
英文:

I have a simple project in Java that uses Jakarta Persistence. I'm running the tests using JUnit Jupiter, Testcontainers, and JBoss Weld.

This is one test:

@EnableAutoWeld
@Testcontainers
@AddBeanClasses({ CategoryRepository.class, EntityManagerProducer.class })
final class CategoryRepositoryTest {
  public static final String POSTGRES_15_3 = "postgres:15.3-alpine3.18";

  @Container
  private final PostgreSQLContainer<?> container = new PostgreSQLContainer<>(DockerImageName.parse(POSTGRES_15_3));

  @Inject
  private CategoryRepository repository;

  @Test
  void save() {
    repository.save(new Category(1L, "Name", "Description"));
    // ...assertions here
  }
}

I'm certain the container is started and exposed through port 5432. The default database, username, and password are all defaulted to test — and that's what I'm using in persistence.xml.

<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="https://jakarta.ee/xml/ns/persistence"
    xsi:schemaLocation="https://jakarta.ee/xml/ns/persistence https://jakarta.ee/xml/ns/persistence/persistence_3_0.xsd"
    version="3.0">
  <persistence-unit name="test">
    ...
    <properties>
      <property name="jakarta.persistence.jdbc.driver" value="org.postgresql.Driver" />
      <property name="jakarta.persistence.jdbc.password" value="test" />
      <property name="jakarta.persistence.jdbc.url" value="jdbc:postgresql://localhost:5432/test" />
      <property name="jakarta.persistence.jdbc.user" value="test" />
      <property name="jakarta.persistence.provider" value="org.eclipse.persistence.jpa.PersistenceProvider" />
      <property name="jakarta.persistence.schema-generation.create-script-source" value="database/schema.sql" />
      <property name="jakarta.persistence.schema-generation.database.action" value="create" />
      <property name="jakarta.persistence.sql-load-script-source" value="database/data.sql" />
      <property name="jakarta.persistence.transactionType" value="RESOURCE_LOCAL" />
    </properties>
  </persistence-unit>
</persistence>

I do have the following (relevant to this issue) dependencies in the Gradle build script:

  • runtimeOnly("org.postgresql:postgresql:42.6.0")
  • testImplementation("org.jboss.weld:weld-junit5:4.0.0.Final")
  • testImplementation("org.testcontainers:junit-jupiter:1.18.3")
  • testImplementation("org.testcontainers:postgresql:1.18.3")

...but still, the tests are unable to connect to the running Docker container:

I've also tried setting .withNetworkAliases("some_alias") and using some_alias as the hostname, but the error message is similar.

Basically, the tests are unable to access the running Docker container with the provided settings. Not sure why this is happening, but looks like I'm missing something obvious.

答案1

得分: 0

问题出在端口号上。每次Testcontainers启动一个新的Docker容器时，内部端口 5432都会映射到一个随机端口 — 这个随机端口应该被使用。

我最终采用了这种方法，使用了特别修改过的JDBC URL Driver，所以我进行了以下更改：

  • 移除了org.testcontainers:junit-jupiter:1.18.3

  • 移除了JUnit Jupiter的设置 — 在测试中的Testcontainers特定的注解等。

  • 更新了jakarta.persistence.jdbc.driver的值为org.testcontainers.jdbc.ContainerDatabaseDriver — 尽管也可以使用org.postgresql.Driver

  • 更新了jakarta.persistence.jdbc.url的值为jdbc:tc:postgresql:15.3-alpine3.18:///jakarta_persistence?currentSchema=my_schema_name

英文:

The issue was around the port numbers. Every time Testcontainers starts a new Docker container, the internal port 5432 is mapped to a random port — and that's the one should be used.

I ended up using the approach with the specially modified JDBC URL Driver, so I made the following changes:

  • Remove org.testcontainers:junit-jupiter:1.18.3

  • Remove the JUnit Jupiter setup — Testcontainers-specific annotations within tests, etc.

  • Update jakarta.persistence.jdbc.driver's value to org.testcontainers.jdbc.ContainerDatabaseDriver — although it works as well with org.postgresql.Driver

  • Update jakarta.persistence.jdbc.url's value to jdbc:tc:postgresql:15.3-alpine3.18:///jakarta_persistence?currentSchema=my_schema_name
