Question

我不知道为什么我的EndPoint被标记为SUSPENDED而我的应用程序没有收到服务返回。

这显示在日志上：

EndPoint会在几秒钟后自动返回，但我怎么知道什么是错的？

收到我的请求后出现错误：

当ESB无法通过该特定端点发送消息时，端点将被暂停。您可以在端点配置中找到端点挂起参数。如果您看到http-outgoing-15544: Connection time out while in state: REQUEST_DONE，则会发生这种情况，因为ESB与后端服务器之间的连接超时。默认套接字超时是60秒。您可以将其增加到120秒并检查。为此，编辑 passthru-http.properties文件为;

http.socket.timeout = 120000

启用ESB wirelogs，以便您可以找到更多信息。 @ log4j属性文件，添加以下行并重启服务器。

log4j.logger.org.apache.synapse.transport.http.wire=DEBUG

EndPoint将标记为SUSPENDED WSO2 ESB
