ElasticSearch 7.x 默认不在支持指定索引类型，在elasticsearch7.x上执行：
put es_test
{
"settings":{
"number_of_shards" : 3,
"number_of_replicas" : 0
},
"mappings":{
"books":{
"properties":{
"title":{
"type":"text"},
"name":{
"type":"text","index":false},
"publish_date":{
"type":"date","index":false},
"price":{
"type":"double"},
"number":{
"type":"object",
"dynamic":true
}
}
}
}
}
执行结果则会出错：Root mapping definition has unsupported parameters
{
"error": {
"root_cause": [
{
"type": "mapper_parsing_exception",
"reason": "Root mapping definition has unsupported parameters: [books : {properties={number={dynamic=true, type=object}, price={type=double}, name={index=false, type=text}, title={type=text}, publish_date={index=false, type=date}}}]"
}
],
"type": "mapper_parsing_exception",
"reason": "Failed to parse mapping [_doc]: Root mapping definition has unsupported parameters: [books : {properties={number={dynamic=true, type=object}, price={type=double}, name={index=false, type=text}, title={type=text}, publish_date={index=false, type=date}}}]",
"caused_by": {
"type": "mapper_parsing_exception",
"reason": "Root mapping definition has unsupported parameters: [books : {properties={number={dynamic=true, type=object}, price={type=double}, name={index=false, type=text}, title={type=text}, publish_date={index=false, type=date}}}]"
}
},
"status": 400
}
如果在6.x上执行，则会正常执行
{
"acknowledged" : true
}
出现这个的原因是，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
所以在Elasticsearch7中应该这么创建索引
put /test
{
"settings":{
"number_of_shards":3,
"number_of_replicas":2
},
"mappings":{
"properties":{
"id":{
"type":"long"},
"name":{
"type":"text","analyzer":"ik_smart"},
"text":{
"type":"text","analyzer":"ik_max_word"}
}
}
}
put /test1
{
"settings":{
"number_of_shards":3,
"number_of_replicas":2
},
"mappings":{
"properties":{
"id":{
"type":"long"},
"name":{
"type":"text"},
"text":{
"type":"text"}
}
}
}
