使用maven测试运行spring boot集成测试但是嵌入式tomcat没有启动答案

【问题标题】：Run spring boot integration test using maven test but the embeded tomcat is not started使用maven测试运行spring boot集成测试但是嵌入式tomcat没有启动

【问题描述】：

我为我的 Spring Boot 应用程序编写了一个集成测试，它显示为以下代码。它在 Eclipse IDE 中运行良好，作为 Junit 测试运行，嵌入的 tomcat 会自动启动和关闭。但是当我使用 maven install 运行它时，它失败了，因为嵌入的 tomcat 没有启动。我是否需要在 Maven 中进行更多配置？怎么做？

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = TestCoreConfig.class)
@WebAppConfiguration
@IntegrationTest
public class UserRegistrationTest {

@Autowired
private Receiver receiver;


@Test
public void shouldRegisterUser() {
    //Given
    String email = System.currentTimeMillis() + "-a-foo@bar.com";

    //When
    ResponseEntity<UserInfo> entity = registerUser(email);

    //Then
    assertEquals(HttpStatus.OK, entity.getStatusCode());

    UserInfo registeredUser = entity.getBody();
    System.out.println ("The registered user ID is " + registeredUser.getUserId());

    String receivedMessages = receiver.getMessages().toString();
    assertTrue(receivedMessages + " expected to contain " + email,   receivedMessages.indexOf(email) != -1);
}

private ResponseEntity<UserInfo> registerUser(String email) {
    String password = "secret";
    UserInfo userInfo = new UserInfo(email, password);

    RestTemplate restTemplate = new RestTemplate();
    return restTemplate.postForEntity("http://localhost:8080/users/registration", userInfo,  UserInfo.class);
}
}

【问题讨论】：

看起来 Tomcat 在运行时可能不在类路径中，并带有 maven 测试。知道为什么吗？你有没有给他们什么特殊待遇？
这里复制maven文件。我是 Spring Boot 的初学者。我应该在 maven 文件中配置嵌入式 tomcat 服务器吗？怎么做？我的机器上还没有安装tomcat。如果使用gradle，似乎没有配置tomcat，知道吗？谢谢。
看起来不错。也许你有港口冲突？是否有任何东西与您的应用在同一端口上运行（默认为 8080）？
最近被别的东西屏蔽了，抱歉回复晚了。它不应该是端口冲突。我检查了没有使用 8080。当我首先运行“mvn spring-boot:run”，然后运行“mvn install”时，一切正常，测试用例可以通过。看来我必须为spring boot集成测试配置maven？
什么意思？当它失败时你是如何运行测试的？（不，maven 配置没有什么特别之处 - 它只是设置类路径。）

【解决方案1】：

扫描端口，将服务器端口设置为找到的空闲端口

@IntegrationTest("server.port:0")

发现端口号

@Value("${local.server.port}")
int port;

将端口添加到网址

restTemplate.postForEntity("http://localhost:"+port+"/users/registration"...

【讨论】：

这应该被标记为正确答案。非常适合我。谢谢@Miodigy
应该标记为正确答案。这对我有用。

【解决方案2】：

Spring 2.0 更新。

我的 Tomcat 在运行应用程序时启动良好，但在我的测试中没有启动。 @Miodigy 的回答对我不起作用，但确实如此：

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@RunWith(SpringRunner.class)
class TokenTest {
    @Autowired private SavedSearchesController controller
    @LocalServerPort private int port

重点是：

@SpringBootTest - 确保添加webEnvironment 参数。

@LocalServerPort - 这是 spring 注入随机端口的地方。

没有webEnvironment Tomcat 在我的测试中没有为我启动。
