需求
上篇文章主要講了一個springboot集成webservice的例子,這次我們根據已經做好的webservice服務端,做一個soap接口請求,要求請求以soap報文方式請求,返回值爲xml格式
這是上篇:springboot集成webservice以及遇到的問題
soap請求接口實現
這是請求報文以及響應的報文的信息
soap接口所需要的參數信息:
soap接口代碼如下:
public static void main(String[] args) {
String postUrl="http://localhost:8888//services/user?wsdl";//webservicve接口地址
String soapAction="";//"http://tempuri.org/execute";
String namespace="http://webservice.zjqf.com/";//命名空間
int paramsNum=0;//參數個數
String[] params={};//參數組
String result=SoapUtil.SplicingMessage(namespace, postUrl, soapAction, "getAllData", paramsNum, params);//訪問接口
System.out.println("返回的數據爲:"+result);
}
工具類soapUtil
/**
* 訪問webservice接口
* @param namespace 命名空間
* @param postUrl webservice接口地址
* @param soapAction soapAction地址
* @param method 方法名
* @param paramsNum 參數個數
* @param params 參數組
* @return 返回值
*/
public static String SplicingMessage(String namespace,String postUrl,String soapAction,String method,int paramsNum,String[] params){
//自定義soap報文模板 注意:xmlns:web 與<soapenv:Body>後的屬性(web)要一致
StringBuffer sb=new StringBuffer("<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:web=\"");
sb.append(namespace);
sb.append("\"><soapenv:Header/><soapenv:Body><web:");
sb.append(method);
sb.append(">");
for (int i = 0; i < paramsNum; i++) {
sb.append("<arg0>"+params[i]+"</arg0>");
}
sb.append("</web:");
sb.append(method);
sb.append("></soapenv:Body></soapenv:Envelope>");
String result=doPostSoap1_1(postUrl, sb.toString(), soapAction);
// int start = result.indexOf("<return>")+8;
// int end = result.indexOf("</return>");
// return result.substring(start,end);
return result;
}
/**
* 使用SOAP1.1發送消息
*
* @param postUrl
* @param soapXml
* @param soapAction
* @return
*/
public static String doPostSoap1_1(String postUrl, String soapXml,
String soapAction) {
String retStr = "";
// 創建HttpClientBuilder
HttpClientBuilder httpClientBuilder = HttpClientBuilder.create();
// HttpClient
CloseableHttpClient closeableHttpClient = httpClientBuilder.build();
HttpPost httpPost = new HttpPost(postUrl);
// 設置請求和傳輸超時時間
RequestConfig requestConfig = RequestConfig.custom()
.setSocketTimeout(socketTimeout)
.setConnectTimeout(connectTimeout).build();
httpPost.setConfig(requestConfig);
try {
httpPost.setHeader("Content-Type", "text/xml;charset=UTF-8");
httpPost.setHeader("SOAPAction", soapAction);
StringEntity data = new StringEntity(soapXml,
Charset.forName("UTF-8"));
httpPost.setEntity(data);
CloseableHttpResponse response = closeableHttpClient
.execute(httpPost);
HttpEntity httpEntity = response.getEntity();
if (httpEntity != null) {
// 打印響應內容
retStr = EntityUtils.toString(httpEntity, "UTF-8");
}
// 釋放資源
closeableHttpClient.close();
} catch (Exception e) {
}
return retStr;
}
返回xml信息:
題外
以下純屬個人理解,如果有誤,感謝大家指正
-
如果要返回xml格式的話,一定要將Content-Type設置爲xml格式;
httpPost.setHeader("Content-Type", "text/xml;charset=UTF-8"); 如果要返回json格式,需變爲json
-
自定義soap模板時,此處不適用含有@WebMethod修飾的方法 因爲他需要指定的參數名字,而這裏使用的都是arg0
for (int i = 0; i < paramsNum; i++) { sb.append("<arg0>"+params[i]+"</arg0>"); }
另外,對於處理這些soap報文請求時,推薦大家一款接口測試神器:soapUi
