elasticsearch 插入数据

1、单条插入（推荐设定主键id防止重复）

public static String addIndex(String index,String type,HashMap<String, Object> hashMap){  
                  hashMap.put("id", "3");  //这里如果不指定id的话elasticsearch会自动创建主键id，
                  hashMap.put("title","双宿双飞从");
                  hashMap.put("describe", "测试123");  
                  hashMap.put("author", "测试doc");  
                TransportClient client=EsClientPool.getInstance().getClient();
                try {  
                    IndexResponse response = client.prepareIndex(index, type,hashMap.get("id").toString())
                            .setSource(hashMap).execute().actionGet();
                    System.out.println(response.getId());
                    return response.getId();  //返回主键
                } catch (Exception e) {
                    // TODO: handle exception
                    return null;
                }finally{
                    client.close();//关闭连接
                }
            }

2、批量插入

public static void addAllIndex(String index,String type,HashMap<String, Object> hashMap){
                      hashMap.put("title","双宿双飞从");
                      hashMap.put("describe", "测试123");  
                      hashMap.put("author", "测试doc");  
                    TransportClient client=EsClientPool.getInstance().getClient();
                    try {
                        BulkRequestBuilder bulkRequest = client.prepareBulk();
                        for (int i = 0; i < 10000; i++) {
                            bulkRequest.add(client.prepareIndex(index, type).setSource(hashMap));
                            // 每1000条提交一次
                            if (i % 10000 == 0) {
                                bulkRequest.execute().actionGet();
                            }
                        }
                    } catch (Exception e) {
                    }finally{
                        client.close();
                    }
            }
