这个请求在kibana 直接查询没有问题,但是调用java api 后 api报错,mapping设置该字段为float,

es2.2 java api就没有这个问题。目前发现只有es 5.4这个版本有问题。哪位大神之前遇到过这个问题。有什么办法可以解决

应该是客户端代码里将查询的数值定义成了java.math.BigDecimal,而ES不支持这个类型。只所以2.2没有问题,是因为之前的transport client发送数据之前将其序列化成了json,而在 5.x以后,使用的内部的transport protocol,数据类型如果不匹配会抛错误。
 
所以数据类型的定义上,需要使用ES支持的类型。
