当management.port=0时在运行时获取Spring Boot管理端口

Question

我正在寻找有关如何在集成测试中将management.port属性设置为0时获得分配给服务于执行器endpoint的嵌入式tomcat的端口的建议。

Im使用带有以下application.yml配置的Spring Boot 1.3.2：

server.port: 8080
server.contextPath: /my-app-context-path

management.port: 8081
management.context-path: /manage

...

@WebIntegrationTest({ "server.port=0", "management.port=0" })

@Component
@Profile("testing")
class TestserverInfo {

    @Value( '${server.contextPath:}' )
    private String contextPath;

    @Autowired
    private EmbeddedWebApplicationContext server;

    @Autowired
    private ManagementServerProperties managementServerProperties


    public String getBasePath() {
        final int serverPort = server.embeddedServletContainer.port

        return "http://localhost:${serverPort}${contextPath}"
    }

    public String getManagementPath() {
        // The following wont work here:
        // server.embeddedServletContainer.port -> regular server port
        // management.port -> is zero just as server.port as i want random ports

        final int managementPort = // how can i get this one ?
        final String managementPath = managementServerProperties.getContextPath()

        return "http://localhost:${managementPort}${managementPath}"
    }
}

我完全知道可以通过使用local.server.port获得标准端口，对于名为local.management.port的管理endpoint，似乎有一些等价物。但那个似乎有不同的含义。

编辑：官方文档没有提到这样做的方法：（http://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#howto-discover-the-http-port-at-runtime）

目前是否有任何未记录的方法可以使用该管理端口？

由于我正在使用Spock-Framework和Spock-Spring来测试我的spring-boot应用程序，所以我必须使用以下方法初始化应用程序：

@ContextConfiguration(loader = SpringApplicationContextLoader.class, classes = MyApplication.class)

java.lang.IllegalArgumentException: Could not resolve placeholder 'local.management.port' in string value "${local.management.port}"

@Autowired
ManagementServerProperties managementServerProperties

@Autowired
Environment environment

public String getManagementPath() {
    final int managementPort = environment.getProperty('local.management.port', Integer.class)
    final String managementPath = managementServerProperties.getContextPath()

    return "http://localhost:${managementPort}${managementPath}"
}

这就是我的操作方法，直接从我的测试类复制（我使用RestAssured进行断言）：

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.test.SpringApplicationConfiguration;
import org.springframework.boot.test.WebIntegrationTest;

import org.springframework.test.annotation.DirtiesContext;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import static com.jayway.restassured.RestAssured.get;
import static org.hamcrest.CoreMatchers.equalTo;

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(Application.class)
@WebIntegrationTest(randomPort = true, value = {"management.port=0", "management.context-path=/admin"})
@DirtiesContext
public class ActuatorEndpointTest {

    @Value("${local.management.port}")
    private int localManagementPort;

    @Test
    public void actuatorHealthEndpointIsAvailable() throws Exception {

        String healthUrl = "http://localhost:" + localManagementPort + "/admin/health";
        get(healthUrl)
                .then()
                .assertThat().body("status", equalTo("UP"));
    }
