为什么我exception在尝试连接到web-service. 我在堆栈溢出中搜索相关错误，但实际上无法弄清楚为什么？

我将假设“com.Webservice.downloadFileAddPassword”是您创建的包，而您的 Web 服务是 Webservice.java。如果这是真的，那么您的 Webservice.java 的第 192 行有一个错误。这并不是说您可能没有访问 Web 服务，而是您的 Web 服务中的操作时间或进程正在超时。您是否对您的网络服务进行了单元测试？

我在堆栈跟踪中读到您有一个正在调用的 InputStream，当您尝试连接或从源读取时，它会花费太长时间而超时。http://docs.oracle.com/javase/7/docs/api/java/net/SocketTimeoutException.html

所以基本上：webservice 使用的输入流耗时太长。我认为我知道的还不够多，只能查看您的堆栈跟踪并提供更多信息。
