scala 踩坑记

1、scala 中使用 fastjson 时，会报错：

Error:(34, 18) ambiguous reference to overloaded definition,
both method toJSONString in object JSON of type (x$1: Any, x$2: com.alibaba.fastjson.serializer.SerializerFeature*)String
and  method toJSONString in object JSON of type (x$1: Any)String
match argument types (Object) and expected result type Any
    println(JSON.toJSONString(value))

解决办法：

println(JSON.toJSONString(value))

改为

println(JSON.toJSONString(info, SerializerFeature.EMPTY: _*))
