前段時間剛好學了一點webservice，因此想和大家分享一下我的成果，因為能力原因，只能做個小實例，望大家見諒！
此實例的思路是：（1）用String類型構造好需要發送的報文;(2)使用axis調用服務發送報文; (3)將返回的報文進行解析。
如下是axis所使用的包：
接下來是實例代碼：
1 //測試實例 2 public class test { 3 4 public static void main(String[] args) { 5 // TODO Auto-generated method stub 6 test t=new test(); 7 //發送的報文 8 String requestXml="<?xml version=\"1.0\" encoding=\"UTF-8\"?><service xmlns=\"http://www.chinatax.gov.cn/spec/\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"><head><tran_id>SWNDPJ</tran_id><channel_id>SWZJ</channel_id><tran_seq>sdfas123</tran_seq><tran_date>20151102</tran_date><tran_time>14494777</tran_time><rtn_code>0</rtn_code><rtn_msg><Code>0000</Code><Message>交易成功</Message><Reason>獲取納稅人年度評價結果成功。</Reason></rtn_msg><expand><name>identityType</name><value></value></expand><expand><name>sjry</name><value></value></expand><expand><name>sjjg</name><value></value></expand></head><body><![CDATA[<?xml version=\"1.0\" encoding=\"UTF-8\"?><taxML xsi:type=\"nsxyPjxxYwbw\" bbh=\"v1.0\" xmlbh=\"String\" xmlmc=\"String\" xsi:schemaLocation=\"http://www.chinatax.gov.cn/dataspec/TaxMLBw_NSXY_PJXX_00001_Response_V1.0.xsd\" xmlns=\"http://www.chinatax.gov.cn/dataspec/\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"><nsxypjxx><nsxypjxxHead><type>NSXY</type><pjlx>NSXY</pjlx></nsxypjxxHead><nsxypjxxBody><nsrsbh>4406817919</nsrsbh><nsrmc></nsrmc><pjnd>2015</pjnd><pjjb></pjjb><pjfs></pjfs><sflhpj>1</sflhpj></nsxypjxxBody></nsxypjxx></taxML>]]></body></service>";;

當然，發送的報文格式因他人提供的文檔類型定義而不同，故解析報文的方法也不同，但大體思路如此，故此代碼只供參考。
