Question

我正在测试spring-boot应用程序并希望检查简单的get请求。问题是如果我用我们的开发服务器替换localhost一切正常。但不是localhost。

这是父测试类：

@RunWith(SpringRunner.class)
@SpringBootTest(classes = MyServiceStarter.class)
public abstract class AbstractModulIntegrationTest { ... }

问题：

@Test
    public void testGetRequest() {
        CredentialsProvider provider = new BasicCredentialsProvider();
        UsernamePasswordCredentials credentials
                = new UsernamePasswordCredentials("user", "pass");
        provider.setCredentials(AuthScope.ANY, credentials);

        HttpClient httpClient = HttpClientBuilder.create()
                .setDefaultCredentialsProvider(provider)
                .build();

        HttpGet request = new HttpGet("http://localhost:9000/abc/v1/users/001");
        HttpResponse response = null;
        try {
            response = httpClient.execute(request);  //HERE IT FAILS
        } catch (IOException e) {
            e.printStackTrace();
        }
        System.out.println("RETURN CODE:" + response.getStatusLine().getStatusCode());
    }

Stracktrace：

org.apache.http.conn.HttpHostConnectException: Connect to localhost:9000 [localhost/127.0.0.1, localhost/0:0:0:0:0:0:0:1] failed: Connection refused: connect

感谢任何帮助。

默认情况下，

@SpringBootTest无法启动Web服务器。您可以使用webEnvironment属性

要求它在已定义的端口或随机端口上启动

@RunWith(SpringRunner.class)
@SpringBootTest(classes = MyServiceStarter.class, webEnvironment = RANDOM_PORT)
public abstract class AbstractModulIntegrationTest { ... }

您可以按如下方式在测试中注入服务器的实际端口：

@LocalServerPort
private int port;

public void testGetRequest() {  ... }

如果要在已定义的端口上启动，可能已将应用程序配置为从端口9000（server.port=9000）开始。然后你应该这样做：

@RunWith(SpringRunner.class)
@SpringBootTest(classes = MyServiceStarter.class, webEnvironment = DEFINED_PORT)
public abstract class AbstractModulIntegrationTest { ... }

在测试执行期间无法连接到localhost
