Spring Boot Integration测试随机空闲端口

问题描述

我能够获得Spring Boot集成，以生成一个随机的自由端口来启动自身.但是我还需要一个Redis的免费端口.

I am able to get Spring Boot integration to generate a random free port to launch itself on. But I also need a free port for Redis.

@ContextConfiguration(classes = {MyApplication.class}, loader = SpringApplicationContextLoader.class)
@WebIntegrationTest(randomPort = true, value = "server.port:0")
@ActiveProfiles(profiles = {"local"})
public class SegmentSteps {

    private static final String HOST_TEMPLATE = "http://localhost:%s";

    // Needs to be a random open port
    private static final int REDIS_PORT = 6380;

    private String host;
    @Value("${local.server.port}")
    private int serverPort;

    private RedisServer redisServer;

    @Before
    public void beforeScenario() throws Exception {
        host = String.format(HOST_TEMPLATE, serverPort);
        redisServer = RedisServer.builder()
                .redisExecProvider(RedisExecProvider.defaultProvider())
                .port(REDIS_PORT)
                .setting("bind 127.0.0.1")
                .build();
        redisServer.start();
    }

    ...
}

关于如何实现这一目标的任何想法?

Any ideas on how to achieve this?

推荐答案

您可以使用Spring Framework的 SocketUtils 以获得可用端口:

You can use Spring Framework's SocketUtils to get an available port:

int redisPort = SocketUtils.findAvailableTcpPort();
