一、基礎進階
- httpclient調用WebService
package com.demo;
import com.midea.gls.MobileCodeWS;
import com.midea.gls.MobileCodeWSSoap;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.NameValuePair;
import org.apache.http.client.HttpClient;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.message.BasicNameValuePair;
import org.apache.http.util.EntityUtils;
import java.io.IOException;
import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;

*/
public class WSHttpClient {
public static void main(String[] args) {
String mobileCode = "18680586568";
// get(mobileCode);
// post(mobileCode);
soap(mobileCode);
}
public static void get(String mobileCode){
HttpClient client = HttpClients.createDefault();
HttpGet httpGet = new HttpGet("http://ws.webxml.com.cn//WebServices/MobileCodeWS.asmx/getMobileCodeInfo?mobileCode="+mobileCode+"&userID=");
try {
HttpResponse response = client.execute(httpGet);
System.out.println("executing request " + httpGet.getURI());
// 獲取響應實體
HttpEntity entity = response.getEntity();
System.out.println("--------------------------------------");
// 打印響應狀態
System.out.println(response.getStatusLine());
if (entity != null) {
// 打印響應內容長度
System.out.println("Response content length: " + entity.getContentLength());
// 打印響應內容
System.out.println("Response content: " + EntityUtils.toString(entity));
}
System.out.println("------------------------------------");
} catch (IOException e) {
e.printStackTrace();
}
}
public static void post(String mobileCodeVal){
HttpClient client = HttpClients.createDefault();
HttpPost httpPost = new HttpPost("http://ws.webxml.com.cn//WebServices/MobileCodeWS.asmx/getMobileCodeInfo");
try {
//設置參數
List<NameValuePair> list = new ArrayList<NameValuePair>();
list.add(new BasicNameValuePair("mobileCode",mobileCodeVal));
list.add(new BasicNameValuePair("userID",""));
UrlEncodedFormEntity requestEntiry = new UrlEncodedFormEntity(list);
httpPost.setEntity(requestEntiry);
HttpResponse response = client.execute(httpPost);
System.out.println("executing request " + httpPost.getURI());
// 獲取響應實體
HttpEntity httpEntity = response.getEntity();
System.out.println("--------------------------------------");
// 打印響應狀態
System.out.println(response.getStatusLine());
if (httpEntity != null) {
// 打印響應內容長度
System.out.println("Response content length: " + httpEntity.getContentLength());
// 打印響應內容
System.out.println("Response content: " + EntityUtils.toString(httpEntity));
}
System.out.println("------------------------------------");
} catch (IOException e) {
e.printStackTrace();
}
}
public static void soap(String mobileVal){
MobileCodeWS mobileCodeWS = new MobileCodeWS();
MobileCodeWSSoap mobileCodeWSSoap = mobileCodeWS.getMobileCodeWSSoap();
String address = mobileCodeWSSoap.getMobileCodeInfo(mobileVal, null);
System.out.println(address);
}
}
- wsimport調用WSDL
wsimport -s . -p com.midea.gls http://ws.webxml.com.cn/WebServices/MobileCodeWS.asmx?WSDL
找到WSDL中關于service的調用
public static void soap(String mobileVal){
MobileCodeWS mobileCodeWS = new MobileCodeWS();
MobileCodeWSSoap mobileCodeWSSoap = mobileCodeWS.getMobileCodeWSSoap();
String address = mobileCodeWSSoap.getMobileCodeInfo(mobileVal, null);
System.out.println(address);
}
二 、 發布自己的WSDL
發布自己的WSDL時候,需要注意，地址欄后面要自己加?WSDL
package com.demo;
import javax.jws.WebService;
import javax.xml.ws.Endpoint;
/**
* \* Created with IntelliJ IDEA.
* \* Author: huyi
* \* Date: 2017/2/20 13:32
* \* Description:
* \
*/
@WebService
public class MyWS {
public String sayHello(String name) {
String reVal = name + ", 你好!";
System.out.println(reVal);
return reVal;
}
public static void main(String[] args) {
String address = "http://10.74.96.29/ws";
Endpoint.publish(address , new MyWS());
System.out.println("發布的地址是:"+address);
}
}
訪問http://10.74.96.29/ws?WSDL，可以見到

<soap:address location="http://10.74.96.29/ws"/>
</wsdl:port>
</wsdl:service>
</wsdl:definitions>
三 、客戶端訪問
- 首先在CMD中調用wsimport工具生成本地WebService代碼
wsimport -s . -p com.ws http://10.74.96.29/ws?WSDL
- 導入代碼到本地項目后，直接調用即可
public static void soap2(String mobileVal){
MyWS mobileCodeWS = new MyWS();
String name = "huyi";
String reVal = mobileCodeWS.sayHello(name);
System.out.println(reVal);
}
注意：一個端口可以發布多個Webservice服務
四 、ajax訪問WebService
ajax不能直接訪問WebService，因為存在跨域的問題，需要變通一下，通過ajax調用工程下的客戶端訪問WebService，客戶端可以是一個servlet，或者spring下的controller
ws.jsp
