情况：
页面查询ES数据，Java查询报这个错误，但是，通过打印的语句，构建curl
查询时候又是正常的，这就让我很费解。

报错信息：

这个解决办法其实是正确的，但是，有个前提条件，我们已经导入过模板，所以，可以直接修改模板
而且，这个帖子中的语句，是基于 ES7 的。我所在环境是ES5的，所以，加fielddata=true配置时，还报错。

具体解决办法：
我直接重新创建模板，然后，重新刷一次数据，解决问题。

导入模板语句：

curl -X PUT -u elastic:123456  "http://127.0.0.1:9200/_template/aaa_bbb_info_temple" -H 'Content-Type: application/json' -d'{"template":"aaa_bbb_*","settings":{"index":{"mapping":{"ignore_malformed":"true"},"refresh_interval":"20s","number_of_shards":"5","translog":{"flush_threshold_size":"512mb","sync_interval":"60s","durability":"async"},"number_of_replicas":"1"}},"mappings":{"default":{"properties":{"aaa":{"store":true,"type":"keyword"}}}}}'

查询导入是否成功：文章来源地址https://www.toymoban.com/news/detail-599220.html

curl -H "Content-Type:application/json" -XGET -u elastic:123456 '192.168.92.82:9222/_template/aaa_bbb_info_temple' > aaa_bbb_info_temple.txt
