XContentBuilder 通过for循环执行，创建索引mappin结构

  public void createIndex(String indexName, String type, Map<String, Map<String, String>> proNames, Map<String,Object> settings) throws IOException {



        XContentBuilder builder = XContentFactory.jsonBuilder().startObject().startObject(type).field("dynamic","strict").startObject("properties");



        if (!proNames.isEmpty()){



            for (Map.Entry<String, Map<String, String>> proName: proNames.entrySet()) {



                if (null != proName.getKey()){



                    builder.startObject(proName.getKey());



                    if (!proName.getValue().isEmpty()){



                        for (Map.Entry<String, String> filed : proName.getValue().entrySet()){



                            String pro = filed.getKey();



                            String value = filed.getValue();



                            if( null != pro && null != value) {



                                builder.field(pro,value);



                            }



                        }

                    }



                    builder.endObject();



                }



            }

        }



        builder.endObject().endObject().endObject();



        String mappingStr=builder.string();



        client.admin().indices().prepareCreate(indexName).addMapping(type,mappingStr).setSettings(settings).execute();

    }
