索引字段属性设置通过JAVA API进行弹性搜索

Question

对于elasticsearch，我是否可以使用示例代码将属性分配给索引字段（如在solr中的config.xml中）。用于加载属性文件的Java API代码示例。

Settings settings = ImmutableSettings.settingsBuilder().put("client.transport.sniff", true).build();
        Client client = new TransportClient(settings).addTransportAddress(new InetSocketTransportAddress("localhost", 9300));
        List<XYZ> list = xyz.getObj("5");
        ObjectMapper mapper = new ObjectMapper();
        for(Object obj : list){
            try {

                String json = mapper.writeValueAsString(obj);
                System.out.println(json);

 //I want a code here to load the mapping file and syntax for mapping file,
   through which i can say that only few attributes of this object should be indexed   and rest all to be stored..//                

                IndexRequestBuilder indexRequestBuilder = client.prepareIndex("searchindex", "searchtype", obj.getId());
                indexRequestBuilder.setSource(json);
                indexRequestBuilder.execute().actionGet();
