我如何用Spring-Data-ElasticSearch在elasticsearch中进行集成测试？

Question

下面是我试图作为POC开始的部分,它抛出异常：

    public class EmbeddedElasticConfiguration {

    public static final String VERSION = "6.8.4";
    public static final String DOWNLOAD_DIRECTORY = "<path>\\test-elasticsearch";
    public static final String INSTALLATION_DIRECTORY = "<path>\test-elasticsearch";
    public static final String NAME = "elasticsearch";
    public static final String TRANSPORT_PORT = "9300";
    public static final String HTTP_CLIENT_PORT = "9200";
    public static final String TEST_INDEX = "salesorder";
    public static final String TEST_TYPE = "salesorder";
    public static final String RESOURCE_LOCATION = "src/test/resources/salesorder-mapping.json";
    private ObjectMapper objectMapper = new ObjectMapper();
    EmbeddedElastic embeddedElastic;

    @Test
    public void configure() throws IOException, InterruptedException {
        embeddedElastic = EmbeddedElastic.builder()
                .withElasticVersion(VERSION)
                .withSetting(TRANSPORT_TCP_PORT, 9300)
                .withSetting(CLUSTER_NAME, "my-cluster")
                //.withPlugin("analysis-stempel")
                .withDownloadDirectory(new File(DOWNLOAD_DIRECTORY))
                .withInstallationDirectory(new File(INSTALLATION_DIRECTORY))
                .withSetting(HTTP_PORT, 9200)
                .withIndex(TEST_INDEX, IndexSettings.builder()
                       .withType(TEST_TYPE, readMappingFromJson())
                     .build())
                .build();

        embeddedElastic.start();
    }

    private String readMappingFromJson() throws IOException {
        final File file = ResourceUtils.getFile(RESOURCE_LOCATION);
        String mapping = new String(Files.readAllBytes(file.toPath()));
        System.out.println("mapping: "+ mapping);
        return mapping;
    }

    @After
    public void stopServer() {
        embeddedElastic.stop();
    }
}

我在以下得到以下例外：

pl.allegro.tech.embeddedelasticsearch.EmbeddedElasticsearchStartupException: Failed to start elasticsearch within time-out

    at pl.allegro.tech.embeddedelasticsearch.ElasticServer.waitForElasticToStart(ElasticServer.java:127)

    at com.xxx.elasticsearch.adapter.configuration.EmbeddedElasticConfiguration.configure(EmbeddedElasticConfiguration.java:50)

是否有人可以帮助使用spring-data在elasticsearch中进行集成测试的任何其他选项，或者我应该如何为elasticsearch编写集成测试。

我知道在stackoverflow和embedded-elasticsearch的其他门户上还有其他的答案，但这些都不适合我当前的elasticsearch版本。

您没有编写您使用的JUnit版本。我可以告诉您我们如何在Spring Data Elasticsearch本身中处理这个问题：

对于JUnit4，您可以检查使用Utils类设置本地运行的Elasticsearch节点的JUnit4规则，并在结束时将其删除。

对于JUnit5，您可能会了解当前主分支是如何处理这一点的，相关的类可以在这里找到。
