CXF请求webService超时区分

设置超时代码

JaxWsDynamicClientFactoryclientFactory=JaxWsDynamicClientFactoryStringurl=\"http://192.168.1.56:7001/test?WSDL\";.newInstance();ClientclientTemp=clientFactory.createClient(url);HTTPConduithttp=(HTTPConduit)clientTemp.getConduit();httpClientPolicy.setConnectionTimeout(10);//连接超时httpClientPolicy.setReceiveTimeout(1000);//响应超时http.setClient(httpClientPolicy);Object[]arg;try{HTTPClientPolicyhttpClientPolicy=newHTTPClientPolicy();httpClientPolicy.setAllowChunking(false);//取消块编码Stringresult=\"\";arg=clientTemp.invoke(\"testMothd\",\"8698053\");result=(String)arg[0];e.printStackTrace();}catch(Exceptione){}这部分代码大家在网络上随便搜索都能得到，这个就是CXF设置连接的超时与响应时间的方法。当然小编主要讲的不是这个，主要来说下到底如何区分连接超时，还是响应超时。分析请求错误（5大种）

我们了解到以上的异常发生之后，小编就在异常下了动了点头脑try{arg=clientTemp.invoke(\"testMothd\",\"8698053\");result=(String)arg[0];}catch(Exceptione){e.printStackTrace();Throwableta=e.getCause();if(tainstanceofSocketTimeoutException){System.out.println(\"响应超时\");}elseif(tainstanceofHTTPException){System.out.println(\"服务端地址无效404\");}elseif(tainstanceofXMLStreamException){System.out.println(\"连接超时\");}else{}System.out.println(\"other\");}当然以上调用都是Client类创建成功之后的异常情况处理，至于创建Client类时，发生异常区分方法，按照以上思路同理解决。
