java - 无法连接到 PostgreSQLContainer : java. io.EOFException

Question

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 Debug模式并检查连接，但是我一直在获取

[08001] The connection attempt failed. java.io.EOFException.

完整的异常跟踪:

org.postgresql.util.PSQLException: The connection attempt failed.

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;
}
