在调用第三方提供的webservice接口时我们可以设置超时时间：
HTTPClientPolicy client = new HTTPClientPolicy();
client.setReceiveTimeout(1000 * 10); // 该时间为响应超时。
client.setConnectionTimeout(1000 * 20 ); // 连接超时。
超时后异常：
请求超时 .SocketTimeoutException: connect timed out
响应超时 .SocketTimeoutException: Read timed out

处理超时的时候我们想捕获.SocketTimeoutException异常是捕获不到的，但是有时又需要根据超时返回响应的结果。
经过认真思考终于发现了解决办法：
catch (Exception e) { e.printStackTrace(); Throwable cause = e.getCause(); if (cause.getMessage().indexOf(“Connection refused: connect”) > 0){ System.out.println(“连接异常”); }else if (cause.getMessage().indexOf(“Read timed out”) > 0){ System.out.println(“响应超时”); }else if (cause.getMessage().indexOf(“connect timed out”) > 0){ System.out.println(“连接超时”); }else{ System.out.println(“处理异常”); } }
连接异常：地址连接不可用，可能是服务端没有启动。
