Question

以前我使用的是elasticsearch 2.2，现在我已经升级到elasticsearch 5.1及以下版本是获取传输客户端对象的代码，但面临一个问题。

Settings settings = Settings.builder().put("cluster.name", 
                elasticConfiguration.getProperty("cluster.name", "elasticsearch")).
                put("client.transport.sniff", true).
                build();


        TransportClient client = new PreBuiltTransportClient(settings);
        for(InetSocketTransportAddress address:nodes){
            (client).addTransportAddress(address);
        }



SearchResponse response = null;
        try {
            LOG.debug("search query "+queryBuilder);
            response = client.prepareSearch(CampaignRepository.INDEX_NAME)
                    .setTypes(getTypeName()).setQuery(queryBuilder).execute()
                    .get();
} catch (InterruptedException | ExecutionException e) {
            LOG.error("Error searching result for " + queryBuilder
                    + " Error message " + e.getMessage());
            // e.printStackTrace();
            throw new CampaignSystemException();
        }

但它给了我一个错误，

java.util.concurrent.ExecutionException: SendRequestTransportException[[dHFgT6l][10.10.2.231:9300][indices:data/read/search]]; nested: IOException[can not write type [class com.seamless.ers.campaignsystem.api.model.campaign.CampaignState]];

其中CampaignState是枚举

请帮助!!

在做了一些R＆amp; D之后，发现有一个关于elasticsearch的错误。在ES 2.2中，它用于接受枚举并将其转换为字符串，但在5.1中同样没有发生，这可能会在即将发布的版本中得到修复

从elasticsearch 5.1查询时获取异常
