Question

您好我在使用Play框架和表单（根据https://tools.ietf.org/html/rfc6902）实现补丁操作时遇到了一些麻烦。我们的想法是在补丁操作上进行模式匹配，以确定要采取的操作。到目前为止，我要做的事情是：

 val myForm = Form(
      tuple(
        "op" -> text.verifying(List("replace", "add").contains(_)),
        "path" -> text.verifying(List("/X", "/Y").contains(_)),
        "value" -> of[AnyRef] //does not compile :'(
      )
    )

导致以下错误：＆＃34;无法找到AnyRef的Formatter类型类。＆＃34;

我如何解决这个问题，知道我的值字段可以是不同的类型，具体取决于目标子资源？

我最终没有使用Play表单，而是使用基本读者，执行以下操作：

1. 10000 pushes done at :710.310000000005 msecs
2. 10000 pushes done at :1831.4599999999991 msecs
3. 10000 pushes done at :3018.199999999997 msecs
4. 10000 pushes done at :4113.779999999999 msecs
5. 10000 pushes done at :5144.470000000008 msecs
6. 10000 pushes done at :6588.179999999993 msecs

9. 10000 pushes done at :9795.709999999992 msecs

并在我的控制器中

 case class PatchOperation(operation: String, path: String, value: JsValue)

  implicit val patchOperationReads: Reads[PatchOperation] = (
    (JsPath \ "op").read[String] and
      (JsPath \ "path").read[String] and
      (JsPath \ "value").read[JsValue]
    ) (PatchOperation.apply _)

使用Play表单实现PATCH操作
