}报错原因：
elasticsearch7默认不在支持指定索引类型，默认索引类型是_doc，如果想改变，则配置include_type_name: true 即可(这个没有测试，官方文档说的，无论是否可行，建议不要这么做，因为elasticsearch8后就不在提供该字段)。官方文档：https://www.elastic.co/guide/en/elasticsearch/reference/current/removal-of-types.html
简单说：es6 支持type,es7像es6兼容，将所有的数据表type换为_doc； Es8完全取消收据表概念
报错数据：
{
"mappings":{
"good":{
"properties":{
"id":{
"type":"long",
"fields":{
"keyword":{
"type":"keyword",
"ignore_above":256
}
}
},
"good_sn":{
"type":"text",
"fields":{
"keyword":{
"type":"keyword",
"ignore_above":256
}
}
}
}
}
}
}修改后的正确数据：
{
"mappings":{
"properties":{
"id":{
"type":"long",
"fields":{
"keyword":{
"type":"keyword",
"ignore_above":256
}
}
},
"good_sn":{
"type":"text",
"fields":{
"keyword":{
"type":"keyword",
"ignore_above":256
}
}
}
}
}
}对比发现：取消了数据表：good
添加数据时也可能出现类似错误：
es6 添加数据链接：http://localhost:9200/shop/good/1
es7 添加数据链接：http://localhost:9200/shop/_doc/1
将es6的数据表名good转换为Es7的_doc即可
