elasticsearch - 使用Elasticsearch 2.3准备索引时出现NumberFormatException

Question

我正在使用Elasticsearch 2.3(服务器和Java客户端)

准备索引的代码:

private TransportClient txClient;
// client intialization

Map<String, String> values = new HashMap<String, String>();
values.put("name", "Dev");
values.put("id", "2f3cc5d4-9c4c-4a49-9ebd-c8cd86758118");
values.put("salary", "50000");

IndexResponse response = txClient
             .prepareIndex("novel","books", "1de90f05-7cc8-4796-9e92-5b766e8bb0d1")
             .setSource(values).execute().actionGet();

错误:

第一次，如果您插入具有ID字段的文档，并且其值是任何数字类型，那么如果它在映射中找不到ID字段的任何映射，则会将Long类型设置为IDfield。

因此，如果要将id字段设置为String，则在将任何文档插入索引之前，应在映射中将其显式映射为string数据类型。
