es(Elasticsearch)查询报错: Set fielddata=true on [level] in order to load fielddata in memory by uninverting the inverted index

修改es模板

PUT 索引名称/_mapping/_doc
{
  "properties":{
    "level":{
      "type":"text",
      "fielddata": true
    }
  }
  
}

 

 level是代码中报错的字段，

 

 

或者下面这种简单解决办法

 

简单解决办法，代码查询的时候改为

 searchSourceBuilder.sort("level.keyword", SortOrder.DESC);

加一个

.keyword
