无法创建到 Test Container for DB2 的 JDBC 连接

【中文标题】无法创建到 Test Container for DB2 的 JDBC 连接【英文标题】：Unable to create JDBC connection to Test Container for DB2 【发布时间】：2021-09-14 12:15:00 【问题描述】：我正在使用测试容器进行需要数据库的集成测试。我之前在 MSSQL 上做过这个并且工作正常，但这是我第一次尝试将它与 DB2 一起使用。
<dependency>
<groupId>org.testcontainers</groupId>
<artifactId>db2</artifactId>
<version>1.15.0</version>
<scope>test</scope>
</dependency>
我有这样的设置：
@BeforeClass
public static void setUpClass()
db2Container = new Db2Container("ibmcom/db2")
.acceptLicense()
.withDatabaseName("testDb2")
.withUsername("username")
.withPassword("password")
.withInitScript("initDB2.sql");
db2Container.start();
System.setProperty("general.datasource.jbhdb2p.jdbc-url", db2Container.getJdbcUrl());
System.setProperty("general.datasource.jbhdb2p.username", db2Container.getUsername());
System.setProperty("general.datasource.jbhdb2p.password", db2Container.getPassword());
我之前没有用 DB2 做过测试容器，所以我不确定所需的日志，但它似乎很好，直到它开始永远循环这 3 行：

我找到了一个存储库，其中已经编写了 DB2 集成测试，并尝试在我的机器上克隆和运行它。它提供的日志与我尝试创建的日志相同。这让我觉得我的问题可能是 docker/IDE 问题而不是代码问题。
谁能从这些日志中收集足够的信息来指导我一个方向？谢谢！
【问题讨论】：
让它运行一段时间后出现此错误：10:50:06.675 [main] ERROR org.testcontainers.jdbc.JdbcDatabaseDelegate - Could not obtain JDBC connection 10:50:06.686 [main] ERROR ???? [ibmcom/db2:latest] - Could not start container
是否为 TCPIP 配置了 Db2 实例 (db2inst1)？以用户 db2inst1、db2set -all（应显示 DB2COMM=TCPIP...）和 db2 get dbm cfg | grep SVCENAME 的身份将 shell 放入容器中，应显示类似 50,000 或 60,000 的数字，或 /etc/services 中对应于端口号的单词条目。您的日志文件在连接 URL 中提到端口 49193，这不是默认值。
【参考方案1】：
您可以编写数据源 Bean 类集成测试，并根据来自 postgresqlContainer 或在您的情况下为 DB2 的参数创建数据源
@Configuration
@TestInstance(TestInstance.Lifecycle.PER_CLASS)
@Testcontainers
public class TestConfiguration
PostgreSQLContainer<?> postgres =
new PostgreSQLContainer<>(POSTGRES_TEST_IMAGE)
.withInitScript("somepath/init_postgresql.sql")
@Primary
@Bean
public DataSource dataSource()
HikariConfig hikariConfig=new HikariConfig();
hikariConfig.setJdbcUrl(postgres.getUrl());
hikariConfig.setUsername(postgres.getUsername());
hikariConfig.setPassword(postgres.getPassword());
hikariConfig.setDriverClassName(postgres.getDriverClassName());
HikariDataSource hikariDataSource=new HikariDataSource(hikariConfig);
return hikariDataSource;
并将上面的配置类导入你的springboot测试，它会自动用TestContainer的Postgres数据源覆盖数据源。
你的测试应该是这样的
@ExtendWith(SpringExtension.clas)
@SpringBootTest(classes = DataSourceConfiguration.class, TestConfiguration.class)
@RequiredArgsConstructor(onConstructor = @__(@Autowired))
@TestInstance(TestInstance.Lifecycle.PER_CLASS)
@Testcontainers
public class RepoTest
@Autowired
TestRepository testRepository;
@Test
public void testRepo()
System.out.println("*****************" + testRepository.existsById(1L));
