在scala中使用cire进行json解析

Question

我正试图利用cire在scala中进行json解析。你能帮我从case类中的数据中解析"pocs"吗？这是代码：

import io.circe.Decoder
import io.circe.generic.semiauto.deriveDecoder
import io.circe.parser
val json: String =
"""
{
"segmements": [
{
"tableName": "X",
"segmentName": "XX",
"pocs": [
"[e-mail]",
"[e-mail]"
]
},
{
"tableName": "Y",
"segmentName": "YY",
"pocs": [
"[e-mail]",
"[e-mail]"
]
}
]
}
"""
final case class TableInfo(tableName: String, segmentName: String)
object TableInfo {
implicit final val TableInfoDecoder: Decoder[TableInfo] = deriveDecoder
}
val result = for {
data <- parser.parse(json)
obj <- data.asObject.toRight(left = new Exception("Data was not an object"))
segmements <- obj("segmements").toRight(left = new Exception("Json didn't had the 
segments key"))
r <- segmements.as[List[TableInfo]]
} yield r
println(result)

只需添加类型为String:集合的参数

final case class TableInfo(tableName: String, segmentName: String, pocs: Seq[String])
