我正在尝试重新利用容器，并且正在尝试使用 JUnit5 ExtendWith 功能，但我仍然得到：
连接到 localhost:5432 被拒绝。
如果我在每个测试中都有相同的逻辑，那么一切都会按预期工作。
@Testcontainers
@SpringBootTest
@ExtendWith({PostgresTestContainersExtension.class})
public class ApplicationJUnit5Test {
@Autowired
private HeroClassicJDBCRepository repositoryUnderTest;
@Test
public void test1() {
System.out.println("junit version: " + Version.id());
Collection<Hero> heroes = repositoryUnderTest.allHeros();
assertThat(heroes).hasSize(1);
repositoryUnderTest.addHero(new Hero("bb", "bb"));
Collection<Hero> heroesAfter = repositoryUnderTest.allHeros();
assertThat(heroesAfter).hasSize(2);
}
}
扩展：
public class PostgresTestContainersExtension implements BeforeAllCallback,
BeforeTestExecutionCallback {
private static final String IMAGE_NAME = "registry.mycomp.com/db/mariadb:10.4.11";
@DynamicPropertySource
static void properties(DynamicPropertyRegistry registry) {
registry.add("spring.datasource.url", container::getJdbcUrl);
registry.add("spring.datasource.password", container::getPassword);
registry.add("spring.datasource.username", container::getUsername);
}
@Container
public static PostgreSQLContainer container = new PostgreSQLContainer()
.withUsername("duke")
.withPassword("password")
.withDatabaseName("test");
@Override
public void beforeAll(ExtensionContext extensionContext) {
startContainerIfNeed();
}
@Override
public void beforeTestExecution(ExtensionContext extensionContext) {
startContainerIfNeed();
}
public void startContainerIfNeed() {
if (!container.isRunning()) {
container.start();
}
}
}
