### 环境 ###

elasticsearch7.\* 遇到的问题

### 异常一 ###

#### 报错信息 ####

"type" : "parse_exception",
        "reason" : "unknown key [setting] for create index"

{
        
      "error" : {
        
        "root_cause" : [
          {
        
            "type" : "parse_exception",
            "reason" : "unknown key [mapping] for create index"
          }
        ],
        "type" : "parse_exception",
        "reason" : "unknown key [mapping] for create index"
      },
      "status" : 400
    }

#### 解决办法 ####

**原因**：索引构建问题，仔细核对是否和我的索引格式一致，有问题欢迎留言。

##### 1.curl方式 #####

curl - H "Content-Type: application/json" - XPUT 'http://127.0.0.1:9200/temporary_index_test1' - d '{
    "settings": {
    	"index": {
    		"number_of_shards": 5,
    		"number_of_replicas": 1
    	}
    },
    "mappings": {
    	"properties": {
    		"news_id": {
    			"type": "long"
    		},
    		"news_title": {
