Question

当我尝试索引一个简单的JSON文档时，我在Elasticsearch（0.90）API中收到此错误。

以下是代码：

TransportClient client = new TransportClient().addTransportAddress(new InetSocketTransportAddress("localhost", 9300));
String indexName = "searchwriter-" + FORMAT.format(System.currentTimeMillis());
client.prepareIndex(indexName, "trace", String.valueOf(id++)).setOpType(IndexRequest.OpType.INDEX).setSource(inputLine).execute().actionGet();

上述代码中的

inputLine 不为空。它的价值是

{ “类型”： “MasterCard1”， “名称”： “Zaheen1”}

以下例外：

我用Google搜索，但我找不到原因。有什么想法吗？

那应该有用。所以，我猜想inputLine不包含您认为它包含的内容。尝试使用硬编码版本替换inputLine：

client.prepareIndex(indexName, "trace", String.valueOf(id++)).setOpType(IndexRequest.OpType.INDEX).setSource("{\"type\":\"MasterCard1\",\"name\":\"Zaheen1\"}").execute().actionGet();

看看它是否解决了这个问题。

以防万一，您是否在客户端和服务器上使用相同版本的elasticsearch？
