java - Java 11 上的 SocketTimeout，但 Java 8 上没有

标签 java java-8 okhttp java-11

当我的 Java 程序使用 Java 8 和 Java 11 运行时，我有一个非常奇怪的行为差异。

我正在使用 MSGraph API (1.7.0) 对 Onedrive API 进行多次调用。为了进行这些调用，我使用 4 个并行线程来同步硬盘上的大量文件(大约 1000 个)。

当我使用 Java 8 执行程序时，我没有遇到任何异常。当我使用 java 11 执行它时，我在大约 60% 的调用中得到了 Socket Timeout Exception。

配置IGraphServiceClient ，我使用的是默认配置。就我而言，在这种情况下，HTTP Provider 是 OKHttp3。

有没有人经历过这样的事情？

[UPDATE-1]

这些是我测试过的环境:

  • Oracle 的 JDK 1.8.0_192 --> 完美。大约 400 次调用中没有错误
  • Openjdk 11.0.7 和 Oracle 的 jdk 11.0.3 --> 大量 Sokcet 超时异常

    • 因此，您有堆栈跟踪:

    最佳答案

    JDK9(或 JDK8 252+)上的 OkHttp，默认会协商 HTTP/2。很有可能与这种变化有关。
    尝试构建一个没有 HTTP/2 的客户端，看看你是否仍然遇到这个问题。

      val client = OkHttpClient.Builder()
      .protocols(listOf(Protocol.HTTP_1_1))
      .build()
    如果它修复了问题，则可能是服务器与 HTTP/2 不兼容，或者与连接重用有关，例如单个连接上的请求过多。
