当我尝试连接exception时，为什么会收到此web-service。我在堆栈溢出中搜索相关错误但实际上无法找出原因？

答案 0 :(得分：-1)

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，那么您在Webservice.java的第192行上有错误。这并不是说您可能没有访问Web服务，但是Web服务中的操作时间或进程是超时的。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你有一个你正在调用的InputStream，当你尝试连接或读取源时，它会花费太长时间，它会超时。 http://docs.oracle.com/javase/7/docs/api/java/net/SocketTimeoutException.html

基本上：webservice使用的输入流耗时太长。我认为我不太了解您的堆栈跟踪并提供更多信息。
