項(xiàng)目場景：

今天在用java寫代碼查ES中數(shù)據(jù)的時(shí)候，出現(xiàn)了下面提示的錯(cuò)誤，我排查了一會(huì)才發(fā)現(xiàn)問題

控制臺(tái)提示

原因分析：

ES中地理坐標(biāo)屬性location的數(shù)據(jù)結(jié)構(gòu)是（緯度，經(jīng)度），而我在進(jìn)行字符串拼接的時(shí)候后了中間的逗號，導(dǎo)致插入數(shù)據(jù)錯(cuò)誤。下面就是上面那一段代碼真正有用的部分。

真正錯(cuò)誤原因：

{"error":{"root_cause":[{"type":"parse_exception","reason":"unsupported symbol [.] in 
geohash [30.871729121.81959]"}],"type":"mapper_parsing_exception","reason":"failed to parse 
field [location] of type [geo_point]","caused_by":{"type":"parse_exception","reason":"unsupported symbol [.] in geohash 
[30.871729121.81959]","caused_by":
{"type":"illegal_argument_exception","reason":"unsupported symbol [.] in geohash 
[30.871729121.81959]"}}},"status":400}

錯(cuò)誤寫法：

this.location = hotel.getLatitude()+hotel.getLongitude();

正確寫法：?

this.location = hotel.getLatitude()+","+hotel.getLongitude();

解決方案：

字符串拼接前要多檢查，并且（緯度，經(jīng)度）這個(gè)順序不能顛倒，不然可能會(huì)導(dǎo)致地理位置錯(cuò)誤。文章來源地址http://www.zghlxwxcb.cn/news/detail-505185.html
