java調用webservice接口（.asmx）

java調用webservice接口（.asmx）

該系統提供了webservice接口。現在把記錄一下，方便自己以後用，說不定也能幫到正在看這篇文檔的你。
首先需要確認，我這邊寫的是java後臺直接調用webservice接口，並且接口後綴爲asmx。
下面直接上代碼：

    public static void main(String[] args){
    String url <span class="token operator">=</span> <span class="token string">"http://192.168.7.2:8000/Webservice1.asmx"</span><span class="token punctuation">;</span><span class="token comment">// 提供接口的地址</span>
    String soapaction <span class="token operator">=</span> <span class="token string">"http://tempuri.org/"</span><span class="token punctuation">;</span> <span class="token comment">// 域名，這是在server定義的--不知道的可以問接口提供方，他們一併提供這個</span>
    
    String pageSize <span class="token operator">=</span> <span class="token string">"5"</span><span class="token punctuation">;</span>

嗯，上面這段代碼要想成功運行還需要加載幾個jar包：

activation.jar
axis-1.4.jar
axis-jaxrpc-1.4.jar
commons-discovery-0.5.jar
commons-httpclient.jar
mail.jar
wsdl4j-1.6.3.jar

由於方法中用的幾個接口都是上面幾個jar包提供的，所以缺少jar會報錯。jar包可以到maven倉庫下載。jar包加好以後，main方法就可以直接運行啦~~~
