Elasticsearch索引批量数据-Java API

Question

根据弹性搜索文档，当我们想一次索引批量数据时，可以使用

BulkRequestBuilder bulkRequest = client.prepareBulk();

// either use client#prepare, or use Requests# to directly build index/delete requests
bulkRequest.add(client.prepareIndex("twitter", "tweet", "1")
        .setSource(jsonBuilder()
                    .startObject()
                        .field("user", "kimchy")
                        .field("postDate", new Date())
                        .field("message", "trying out Elasticsearch")
                    .endObject()
                  )
        );

bulkRequest.add(client.prepareIndex("twitter", "tweet", "2")
        .setSource(jsonBuilder()
                    .startObject()
                        .field("user", "kimchy")
                        .field("postDate", new Date())
                        .field("message", "another post")
                    .endObject()
                  )
        );

如果我们希望将10种不同的数据放入索引，但是我有250余种数据放入索引，这是可以的，我的数据当前为json格式，如下所示

    "typeOfRest": "\u0421\u0435\u043c 
  },

我有200多个这样的数据，有没有比一次全部写入字段更好的方法一次索引所有索引了。可以从类路径中调用，因为我所有的数据都在一个名为tour.json

的文件中
