Question

我正在研究一个修补程序，该修补程序需要接受小于1,00,000阈值的SOAP XML请求。这样我们就可以在处理之前验证大型xml文档。

现在，当阈值小于1,00,000时，我对akka的错误报告感到困惑。我注意到如果一个父项下的元素大于2000，则会出现此错误。如果元素被多个父元素划分，则不会出现错误。请帮我找出下面来自akka的错误。

I have also to tried with disabling "akka.jvm-exit-on-fatal-error" in the configuration.

akka {

  jvm-exit-on-fatal-error = off

  actor {
    provider = "akka.remote.RemoteActorRefProvider"
  }

  remote {
    enabled-transports = ["akka.remote.netty.ssl"] 
    .
    .
    .
  }
}

Soap Request Body的示例：

<soapenv:Body>
    <cai3:Create>
        <cai3:Attributes>
            <CreateAttributes attributeId="1">
                <attributeId>12345678</attributeId>
                <!--Zero or more repetitions:-->
                <node1 attributeId="12345678">
                    <node1>12345678</node1>
                    <node1/>
                </node1> 
                .......
                .......
                .......
                .......
                .......
                .......
                .......

                on so on upto 3000 same elements

                </CreateAttributes>
        </cai3:Attributes>
    </cai3:Create>
</soapenv:Body>

看起来您在通过akka-http来使用SOAP消息方面似乎没有问题。

基于您发布的堆栈跟踪信息，问题出在导致java.lang.StackOverflowError的java序列化上，或者是因为您通过akka-remote，akka-cluster发送消息或坚持该消息与akka-persistence。这些是在akka中可以使用Java序列化的地方。除非您确实明确使用它。

您可以了解为什么JavaSerializationIsBroken并导致StackOverflowError错误的原因。

我建议您尝试使用消息，而不涉及akka-remote和akka-persistence。如果这样做确实有帮助，您就知道问题出在Java序列化。

下一步是将Java序列化替换为更现代的序列化协议，例如protocol-buffers。

由于为ActorSystem [mpe] java.lang.StackOverflowError启用了“ akka.jvm-exit-on-fatal-error”启用，因此关闭了JVM
