无法连接到 PostgreSQLContainer:java.io.EOFException
Failed to connect to PostgreSQLContainer: java.io.EOFException
将我的容器创建为:
public static PostgreSQLContainer<?> container = new PostgreSQLContainer<>("postgres:latest");
static {
container.start();
System.setProperty("driver-class-name", container.getDriverClassName());
System.setProperty("spring.datasource.url", container.getJdbcUrl());
System.setProperty("spring.datasource.username", container.getUsername());
System.setProperty("spring.datasource.password", container.getPassword());
}
我试图在启动后进入调试模式并检查连接,但我一直收到
[08001] The connection attempt failed. java.io.EOFException.
完整异常跟踪:
org.postgresql.util.PSQLException: The connection attempt failed.

所以很明显我的应用程序也无法连接到它。
有什么建议吗?
回答我自己的问题,问题是容器无法接收连接,我不确定为什么,cos config 对我来说看起来不错,但可行的解决方案是将容器初始化为 https://www.testcontainers.org/modules/databases/#database-containers-launched-via-jdbc-url-scheme
所以这里是我的工作解决方案的例子,希望它能对某人有所帮助:
@ActiveProfiles("test")
@SpringBootTest(webEnvironment = WebEnvironment.RANDOM_PORT, properties = {
"spring.datasource.url=jdbc:tc:postgresql:12.2:///test?TC_INITSCRIPT=init.sql",
"spring.datasource.driver-class-name=org.testcontainers.jdbc.ContainerDatabaseDriver"
})
abstract class AbstractIntegrationTestCase {
public static GenericContainer<?> container = new PostgreSQLContainer<>("postgres:12.2");
static {
container.start();
}
@Autowired
protected TestRestTemplate restTemplate;
}
