异常名称:ElasticsearchStatusException&illegal_argument_exception
异常分析:按照brand字段进行分组时出现此异常,brand字段mapping出现问题?
异常原因:brand字段初始化时 type 默认为keyword 从而进行了分词,导致在brand字段上做分组时找不到此字段
异常详情:

解决方案:清空index库,重新设定es智能映射模板,将brand字段type设为kyword
PUT /product
{
"mappings": {
"properties": {
"id": {
"type": "keyword"
},
"title": {
"type": "text",
"analyzer": "ik_max_word"
},
"category": {
"type": "keyword"
},
"brand": {
"type": "keyword"
},
"images": {
"type": "keyword",
"index": false
},
"price": {
"type": "double"
}
}
}
}
解决结果：成功
注意事项:对es建index库时一定要确定数据结构,慎重编写映射配置
