** 索引插入信息：people是已经创建好的索引，man是类型、1是id**

创建索引的代码：（在上篇的博客中索引创建中有详细教程创建索引）

{
    	"settings":{
    		"number_of_shards":3,
    		"number_of_replicas":1
    	},
    	"mappings":{
    		"man":{
    			"properties":{
    				"name":{
    					"type":"text"
    				},
    				"country":{
    					"type":"keyword"
    				},
    				"age":{
    					"type":"integer"
    				},
    				"date":{
    					"type":"date",
    					"format":"yyyy-MM-dd HH:mm:ss"
    				}
    			}
    		}
    	}
    }

插入索引信息：

**插入的json:**

{
    	"name": "彭亮",
    	"country": "China",
    	"age": 22,
    	"date": "1997-03-01 00:00:00"
    }

**插入结果：**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQxNDc5NDY0_size_16_color_FFFFFF_t_70][]

**如何在插入数据的同时，让ES自动帮我们产生文档的Id:改成post的形式，然后把id删除，写好json然后点击Send**

**json的代码：**

{
    	"name": "无痕",
    	"country": "China",
    	"age": 21,
    	"date": "1998-03-01 00:00:00"
    }

**点击刷新：可以看见我们刚刚已经创建好的数据**
