elasticsearch7插入数据报错Rejecting mapping update to [mysort] as the final mapping would have more than 1 type: [_doc, article]

elasticsearch7插入数据报错

{
  "error": {
    "root_cause": [
      {
        "type": "illegal_argument_exception",
        "reason": "Rejecting mapping update to [mysort] as the final mapping would have more than 1 type: [_doc, article]"
      }
    ],
    "type": "illegal_argument_exception",
    "reason": "Rejecting mapping update to [mysort] as the final mapping would have more than 1 type: [_doc, article]"
  },
  "status": 400
}

如果是自己新建的mapping，用put /index名/type名/id的方式添加数据时就会报错。原因是elsaticsearch7.x开始就取消了type这个概念。。至于为什么要取消，简单的了解了下，好像是如果多个type里都有相同字段的话处理效率低。
解决方法：
将type名改为_doc，例如：put /index名/_doc/1即可。
