elasticsearch---批量修改，批量更新某个字段

POST /infomations/infomations/_update_by_query

JSON请求格式

{
    "query": {
        "match": {
            "status": "UP_SHELF"
        }
    },
    "script": {
        "inline": "ctx._source[‘status‘] = ‘DOWN_SHELF‘"
    }
}

POST请求/索引/文档名/_update_by_query

主要看一下下面的script

ctx._source[字段名] = “值”;ctx._source[字段名] = “值”;

多个的话就用分号隔开。

        //集群模式，获取链接
        Client client = elasticsearchTemplate.getClient();
        
        UpdateByQueryRequestBuilder updateByQuery = UpdateByQueryAction.INSTANCE.newRequestBuilder(client);
        String name = "修改数值";
        updateByQuery.source("索引")
         //查询要修改的结果集
         .filter(QueryBuilders.termQuery("field", 412))
         //修改操作 
        .script(new Script( "ctx._source[‘field‘]=‘"+ name+"‘;ctx._source[‘field‘]=‘"+name+"‘"));
        //响应结果集
        BulkByScrollResponse response = updateByQuery.get();
        long updated = response.getUpdated();
