Embedded postgres in Quarkus test does not connect

问题

Trying to write up a very simple db IT test using quarkus and an embedded postgres db. But when I run the test it seems to be trying to connect to the default `localhost:5432`. Debugging through the code, there is a different port assigned to the embedded db yet the code flips out saying it can't connect to `localhost:5432` and I have no idea why.
Heres what I have done so far

**PostgresDatabaseTestResource class**
```java
public class PostgresDatabaseTestResource implements QuarkusTestResourceLifecycleManager {

    private static final Logger LOGGER = LoggerFactory.getLogger(PostgresDatabaseTestResource.class);
    private EmbeddedPostgres postgres;

    @Override
    public Map<String, String> start() {
        final String userName = System.getProperty("user.name");
        if ("root".equals(userName)) {
            throw new IllegalStateException("Cannot provision Ephemeral Postgres when running as user: " + userName);
        }
        try {
            postgres = EmbeddedPostgres.builder().start();
        } catch (IOException e) {
            throw new RuntimeException("Could not start Ephemeral Postgres", e);
        }
        Map<String, String> props = new HashMap<>();
        props.put("quarkus.datasource.url", postgres.getJdbcUrl("postgres", "postgres"));
        props.put("quarkus.datasource.username", "postgres");
        props.put("quarkus.datasource.password", "");
        props.put("quarkus.datasource.driver", Driver.class.getName());

        return props;
    }

    @Override
    public void stop() {
        if (postgres != null) {
            try {
                postgres.close();
            } catch (IOException e) {
                LOGGER.warn("Could not stop Ephemeral Postgres", e);
            }
            postgres = null;
        }
    }
}

DatabaseManagerIT class

@QuarkusTest
@QuarkusTestResource(PostgresDatabaseTestResource.class)
public class DatabaseManagerIT {

    @Inject
    JdbiProvider dbi;

    @Test
    public void testMigration() {
        Jdbi jdbi = dbi.get();
        assertNotNull(jdbi);
    }
}

Test logs and exception

I can see in the logs that the db is listening on port 45087. But then in the exception it's...

I can see in the logs that the db is listening on port `45087`. But then in the exception it&#39;s complaining about not being able to connect to port `5432`. Any ideas why I am seeing this?

**Edit**

**Quarkus Version**: 1.4.2.Final

**Application.properties**

quarkus.http.port=8082

DB

#quarkus.datasource.driver=com.mysql.cj.jdbc.Driver

quarkus.datasource.jdbc.acquisition-timeout=PT1M

你将新的数据源配置和旧的已弃用配置混合在一起，所以才导致它无法正常工作。

在你的 `application.properties` 文件中，你应该使用 `quarkus.datasource.jdbc.url`，而在你的 TestResource 中，你为 `quarkus.datasource.url` 设置了一个值。

在你的 TestResource 中，你应该使用：

* `quarkus.datasource.jdbc.url`
* `quarkus.datasource.jdbc.driver`（如果确实需要特定的驱动程序）

然后它应该能正常工作。

You&#39;re mixing the new datasource configuration and the old deprecated one thus why it&#39;s not working.

In your `application.properties`, you have `quarkus.datasource.jdbc.url` which is what you should use, whereas in your TestResource, you push a value for `quarkus.datasource.url`.

In your TestResource, you should use:

* `quarkus.datasource.jdbc.url`
* `quarkus.datasource.jdbc.driver` (if it really needs a specific driver)

Then it should work properly.
