尝试写入结束元素时，无法发送消息、管道损坏、写入 XMLStreamWriter 时出错、没有打开的开始元素

Question

我有两个应用程序 ARMS 和 ODOC， ARMS（服务器）暴露了同步soap web 服务，而ODOC（客户端）正在使用同步soap web 服务。 ODOC 正在向 ARMS 发送请求，几分钟后（比如 3 到 5 分钟），它会超时。 由于连接中断，ODOC 可能无法接收响应，ARMS 也无法发送响应。

问题：

1. 哪个应用程序必须设置超时？以及如何？
2. 超时的最大限制是多少？
3. 默认超时值是多少？
4. 有什么原因在超时后，ODOC 可以收到响应和 ARMS 可以发送响应。

下面是 ARMS 端的堆栈跟踪，同时将响应发送回 ODOC。

Answer 1

1. 哪个应用程序必须设置超时？以及如何？

   一般是它的客户端，但是连接可以在空闲超时/接收超时后被服务器端、网关/防火墙（一般默认20分钟）终止。 CXF客户端配置参数为here，服务端配置参数为here

2. 超时的最大限制是多少？

3. 默认超时值是多少？

   请检查默认超时here

4. 有什么原因在超时后，ODOC 可以收到响应，ARMS 可以发送响应。

   不，但是您可以使用异步客户端，但在这种情况下，您需要组合超时（解决方案只是 NIO，它不会解决实际问题）。

   理想的解决方案是将 JMS/消息与代理一起使用并使您的应用程序异步。您可以通过添加 jms 传输来配置您的 cxf 客户端和服务器，请参阅here 以启用 jms 传输。您可以同时使用 SOAP over JMS 和 SOAP over HTTP 协同工作。
