我的项目取决于 

    <dependency>
        <groupId>org.elasticsearch</groupId>
        <artifactId>elasticsearch</artifactId>
        <version>2.3.3</version>
    </dependency>
    <dependency>
        <groupId>org.elasticsearch.plugin</groupId>
        <artifactId>shield</artifactId>
        <version>2.3.3</version>
    </dependency>

我的TransportClient看起来像这样： 

public synchronized Client getClient(String clusterName, List<String> hosts, Integer port) {
// Build the settings for our client.
Settings settings = Settings.settingsBuilder()
        .put("transport.ping_schedule", "5s")
        .put("cluster.name", clusterName)
        .put("action.bulk.compress", false)
        .put("shield.transport.ssl", true)
        .put("request.headers.X-Found-Cluster", clusterName)
        .put("shield.user", "USERNAME:PASSWORD")
        .build();

TransportClient client = clients.get(clusterName);
if (client == null) {
    client = TransportClient.builder().addPlugin(ShieldPlugin.class).settings(settings).build();

    clients.put(clusterName, client);

    for(String host : hosts) {
        try {
            for (InetAddress address : InetAddress.getAllByName(host)) {
                if (address instanceof Inet4Address) {
                    client.addTransportAddress(new InetSocketTransportAddress(address, port));
                }
            }
        } catch (UnknownHostException e) {
            throw new ElasticSearchException(e);
        }
    }

    try {
        logger.info("Getting cluster health... ");
        ActionFuture<ClusterHealthResponse> healthFuture = client.admin().cluster().health(Requests.clusterHealthRequest());
        ClusterHealthResponse healthResponse = healthFuture.get(5, TimeUnit.SECONDS);
        logger.info("Got cluster health response: [{}]", healthResponse.getStatus());
    } catch(Throwable t) {
        logger.error("Unable to get cluster health response: [{}]", t.getMessage());
    }
}

return client;
}

我的传输客户端如果失败并显示以下堆栈跟踪：

当我运行IDE，IntelliJ时，一切运行正常。但是当我直接运行胖罐时，kaboom。

here描述了这个问题的解释。简而言之，ElasticSearch及其lucene依赖项在META-INF / services中具有冲突的文件，当它们组合在一个jar中时，它们会被相互覆盖。

如果你遇到这个问题，你可能会建立一个罐子。如果您正在使用maven，您可以使用shade插件来解决这个问题，以合并这些文件并防止它们被覆盖：

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
