Es array object update multi-process conflict

Es structure

{
  "_index": "my_index",
  "_type": "my_type",
  "_id": "1",
  "_version": 26,
  "found": true,
  "_source": {
    "group": "fans",
    "user": [
      {
        "first": "John",
        "last": "Smith"
      },
      {
        "first": "Alice",
        "last": "White"
      }
    ]
  }
}

 

}

============================== 
1. Use version control == 
@Test 
public void getOneById() { 
Client client= elasticsearchTemplate .getClient(); 
   GetResponse getResponse = elasticsearchTemplate.getClient() 
         .prepareGet() // Prepare to perform the get operation, and then actually perform the get operation. (Difference from direct get) 
         .setIndex("my_index") // to 
         query.setType("my_type") 
         .setId("1") 
         .get(); 
long l= getResponse.getVersion(); 
String sss= getResponse.getSourceAsString(); 
   System.out.println("sss"); 
   EsService esService= new EsService(); 
  
    String a= getResponse.getSourceAsString(); 
       Supper supper= JSONObject.parseObject(a,Supper.class);
   System.out.println(supper.getUser().size());
   Use use=new Use();
   use.setLast("sbbbbvvs");
   use.setFirst("ss");
   supper.getUser().add(use);
   insertSentimentById("my_index","my_type", supper,"1");

 /* 方法二利用 postscript
  HttpEntity entity = new StringEntity(
         "{\n" +
               "   \"script\" : {\n" +
               "       \"inline\": \"ctx._source.user+=new_tag\",\n" +
               "       \"params\" : {\n" +
               "          \"new_tag\" :[{\n" +
               "            \"first\":\"ddfdd\"\n" +
               "            ,\"last\":\"22f22\"\n" +
               "          },\n" +
               "          {\n" +
               "            \"first\":\"ddfdf\"\n"+
               "            ,\"last\":\"2f222\"\n" +
               "          }\n" +
               "          ]\n" +
               "       }\n" +
               "   }\n" +
               "}", ContentType.APPLICATION_JSON);
   esService.putSync("my_index","my_type","1",entity);*/

}





public void insertSentimentById( String indexName,String type, Supper sentiment,String id ) {
   //IndexQuery indexQuery = new IndexQueryBuilder().withIndexName(indexName).withType(type).withId(sentiment.getId().toString()).withObject(sentiment).build();
   String json= JSONObject.toJSONString(sentiment);
   long v=12;
   boolean insertFlag= false;
   while(true){
      try {
         elasticsearchTemplate.getClient().prepareIndex(indexName, type).setId(id).setVersion(v).setSource(json).execute().actionGet();
         insertFlag=true;
      }catch (Exception e){
         System.out.println(e.getMessage());;
         v=v+1;
      }
      if(insertFlag){
         break;
      }
      logger.info("===="+v);
   }
}
