play 框架中如何在anorm 解析数据库结果时进行datetime格式转换?


我从MySQL取得的数据里有一项是time,取回来的是“yyyy-MM-dd HH:mm:ss”格式的java.sql.timestamp类型的数据,我有下面的代码把time转换成为joda.DateTime类型的数据,然后转为字符串传给前端,但是发现转换成了一串数字的timestamp形式,但是前端需要展示“yyyy-MM-dd HH:mm:ss”格式的时间。请问在服务器后台怎么进行这个格式化?
下面是我的代码。


 import org.joda.time.DateTime

import anorm.SqlParser._
import anorm._
import play.api.db.DB
import play.api.libs.functional.syntax._
import play.api.libs.json._
import play.api.Play.current

                  url: String,//商品url
//                  imgsrc: String,//商品图片(url)
                  price: Double,//商品价格
                  commentnum: Int,//商品评论数
                  likerate:Int,//好评率

                  category:String)

  val jditem = {

    val json:JsValue = Json.toJson(list)
    val jsobject = Json.obj("total"-> list.length,"rows"-> json)
    println("发送的字符串是========"+jsobject.toString())

  }

  def all(): List[String] = DB.withConnection { implicit c =>
