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"}
-
}
-
}
-
-
}
