public String post()
OutputStreamWriter out = null;
StringBuilder sTotalString = new StringBuilder();
try
URL urlTemp = new URL(
"http://www.webxml.com.cn/WebServices/WeatherWebService.asmx/getSupportCity");
URLConnection connection = urlTemp.openConnection();
connection.setDoOutput(true);
out = new OutputStreamWriter(connection.getOutputStream(), "UTF-8");
StringBuffer sb = new StringBuffer();
sb.append("byProvinceName=福建");
out.write(sb.toString());
out.flush();
String sCurrentLine;
sCurrentLine = "";

l_urlStream));
while ((sCurrentLine = l_reader.readLine()) != null)
sTotalString.append(sCurrentLine);
catch (Exception e)
e.printStackTrace();
finally
if (null != out)
try
out.close();
catch (IOException e)
e.printStackTrace();
return sTotalString.toString();

java如何调用webservice接口
Java调用WebService可以直接使用Apache提供的axis.jar自己编写代码,或者利用Eclipse自动生成WebService Client代码,利用其中的Proxy类进行调用。理论上是一样的,只不过用Eclipse自动生成代码省事些。1、编写代码方式:
package com.yudun.test;
import java.rmi.RemoteException;
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import org.apache.axis.message.PrefixedQName;
import org.apache.axis.message.SOAPHeaderElement;
import com.cezanne.golden.user.Exception;
import com.cezanne.golden.user.UserManagerServiceProxy;
import javax.xml.namespace.QName;
import java.net.MalformedURLException;
import javax.xml.rpc.ServiceException;
import javax.xml.soap.Name;
import javax.xml.soap.SOAPException;
public class testWebService
public static String getResult() throws ServiceException, MalformedURLException, RemoteException, SOAPException
//标识Web Service的具体路径
String endpoint = "WebService服务地址";
// 创建 Service实例
Service service = new Service();
// 通过Service实例创建Call的实例
Call call = (Call) service.createCall();
//将Web Service的服务路径加入到call实例之中.
call.setTargetEndpointAddress( new java.net.URL(endpoint) );//为Call设置服务的位置
// 由于需要认证,故需要设置调用的SOAP头信息。
Name headerName = new PrefixedQName( new QName("发布的wsdl里的targetNamespace里的url", "string_itemName") );
org.apache.axis.message.SOAPHeaderElement header = new SOAPHeaderElement(headerName);
header.addTextNode( "blablabla" );
call.addHeader(header);
// SOAPHeaderElement soapHeaderElement = new SOAPHeaderElement("发布的wsdl里的targetNamespace里的url", "SoapHeader");
// soapHeaderElement.setNamespaceURI("发布的wsdl里的targetNamespace里的url");
// try
//
// soapHeaderElement.addChildElement("string_itemName").setValue("blablabla");
//
// catch (SOAPException e)
//
// e.printStackTrace();
//
// call.addHeader(soapHeaderElement);
//调用Web Service的方法
org.apache.axis.description.OperationDesc oper;
org.apache.axis.description.ParameterDesc param;
oper = new org.apache.axis.description.OperationDesc();
oper.setName("opName");
param = new org.apache.axis.description.ParameterDesc(new javax.xml.namespace.QName("", "arg0"), org.apache.axis.description.ParameterDesc.IN, new javax.xml.namespace.QName("http://www.w3.org/2001/XMLSchema", "string"), java.lang.String.class, false, false);
param.setOmittable(true);
oper.addParameter(param);
param = new org.apache.axis.description.ParameterDesc(new javax.xml.namespace.QName("", "arg1"), org.apache.axis.description.ParameterDesc.IN, new javax.xml.namespace.QName("http://www.w3.org/2001/XMLSchema", "string"), java.lang.String.class, false, false);
param.setOmittable(true);
oper.addParameter(param);
param = new org.apache.axis.description.ParameterDesc(new javax.xml.namespace.QName("", "arg2"), org.apache.axis.description.ParameterDesc.IN, new javax.xml.namespace.QName("http://www.w3.org/2001/XMLSchema", "string"), java.lang.String.class, false, false);
param.setOmittable(true);
oper.addParameter(param);
oper.setReturnType(new javax.xml.namespace.QName("http://www.w3.org/2001/XMLSchema", "string"));
oper.setReturnClass(java.lang.String.class);
oper.setReturnQName(new javax.xml.namespace.QName("", "return"));
oper.setStyle(org.apache.axis.constants.Style.WRAPPED);
oper.setUse(org.apache.axis.constants.Use.LITERAL);
oper.addFault(new org.apache.axis.description.FaultDesc(
new javax.xml.namespace.QName("发布的wsdl里的targetNamespace里的url", "Exception"),
"Exception",
new javax.xml.namespace.QName("发布的wsdl里的targetNamespace里的url", "Exception"),
true
));
call.setOperation( oper );
call.setOperationName(new javax.xml.namespace.QName("发布的wsdl里的targetNamespace里的url", "opName"));
//调用Web Service,传入参数
String res = ( String ) call.invoke( new Object[]("arg0","arg1"));
System.out.println("===============");
return res;
/**
* @param args
*/
public static void main(String[] args)
try
System.out.println(getResult());
catch (MalformedURLException e)
e.printStackTrace();
catch (RemoteException e)
e.printStackTrace();
catch (ServiceException e)
e.printStackTrace();
catch (SOAPException e)
e.printStackTrace();
2、利用Eclipse自动生成WebService client代码就容易多了:(由于还不会发图片,就用语言描述了,大家酬和看吧。。。)
首先,new project,选择other,在输入框中输入Web Service Client,选中搜索后的结果,点击Next,在Service definition中输入 WebService的发布地址,点击Finish
这样,WebService Client代码已经生成好了。
接下来写一个Test类,在main函数中输入如下代码:
String endpoint = "服务器的WebService的地址";
YourWebServiceNameProxy umsp = new YourWebServiceNameProxy (endpoint);
try
String resultStr = umsp.opMethod("arg0","arg1");
System.out.println(resultStr);
catch (Exception e)
System.out.println("异常");
e.printStackTrace();
catch (RemoteException e)
System.out.println("RemoteException异常");
e.printStackTrace();
如果还有疑问的话还有视频,如果对你有帮助请采纳! 参考技术A Java通过WSDL文件来调用webservice:
注意,以下的代码并没有经过真正的测试,只是说明这些情况,不同版本的Axis相差很大,大家最好以apache网站上的例子为准,这里仅仅用于说明其基本用法。
1,直接AXIS调用远程的web service
这种方法比较适合那些高手,他们能直接看懂XML格式的WSDL文件,我自己是看不懂的,尤其我不是专门搞这行的,即使一段时间看懂,后来也就忘记了。直接调用模式如下:
import java.util.Date;
import java.text.DateFormat;
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import javax.xml.namespace.QName;
import java.lang.Integer;
import javax.xml.rpc.ParameterMode;
public class caClient
public static void main(String[] args)
try
String endpoint = "http://localhost:8080/ca3/services/caSynrochnized?wsdl";
//直接引用远程的wsdl文件
//以下都是套路
Service service = new Service();
Call call = (Call) service.createCall();
call.setTargetEndpointAddress(endpoint);
call.setOperationName("addUser");//WSDL里面描述的接口名称
call.addParameter("userName", org.apache.axis.encoding.XMLType.XSD_DATE,
javax.xml.rpc.ParameterMode.IN);//接口的参数
call.setReturnType(org.apache.axis.encoding.XMLType.XSD_STRING);//设置返回类型
String temp = "测试人员";
String result = (String)call.invoke(new Object[]temp);
//给方法传递参数,并且调用方法
System.out.println("result is "+result);
catch (Exception e)
System.err.println(e.toString());
2,直接SOAP调用远程的webservice
这种模式我从来没有见过,也没有试过,但是网络上有人贴出来,我也转过来
import org.apache.soap.util.xml.*;
import org.apache.soap.*;
import org.apache.soap.rpc.*;
import java.io.*;
import java.net.*;
import java.util.Vector;
public class caService
public static String getService(String user)
URL url = null;
try
url=new URL("http://192.168.0.100:8080/ca3/services/caSynrochnized");
catch (MalformedURLException mue)
return mue.getMessage();
// This is the main SOAP object
Call soapCall = new Call();
// Use SOAP encoding
soapCall.setEncodingStyleURI(Constants.NS_URI_SOAP_ENC);
// This is the remote object we're asking for the price
soapCall.setTargetObjectURI("urn:xmethods-caSynrochnized");
// This is the name of the method on the above object
soapCall.setMethodName("getUser");
// We need to send the ISBN number as an input parameter to the method
Vector soapParams = new Vector();
// name, type, value, encoding style
Parameter isbnParam = new Parameter("userName", String.class, user, null);
soapParams.addElement(isbnParam);
soapCall.setParams(soapParams);
try
// Invoke the remote method on the object
Response soapResponse = soapCall.invoke(url,"");
// Check to see if there is an error, return "N/A"
if (soapResponse.generatedFault())
Fault fault = soapResponse.getFault();
String f = fault.getFaultString();
return f;
else
// read result
Parameter soapResult = soapResponse.getReturnValue ();
// get a string from the result
return soapResult.getValue().toString();
catch (SOAPException se)
return se.getMessage();
3,使用wsdl2java把WSDL文件转成本地类,然后像本地类一样使用,即可。
这是像我这种懒人最喜欢的方式,仍然以前面的global weather report为例。
首先 java org.apache.axis.wsdl.WSDL2Java http://www.webservicex.net/globalweather.asmx.WSDL
原本的网址是http://www.webservicex.net/globalweather.asmx?WSDL,中间个各问号,但是Linux下面它不能解析,所以去掉问号,改为点号。
那么就会出现4个文件:
GlobalWeather.java GlobalWeatherLocator.java GlobalWeatherSoap.java GlobalWeatherSoapStub.java
其中GlobalWeatherSoap.java是我们最为关心的接口文件,如果你对RMI等SOAP实现的具体细节不感兴趣,那么你只需要看接口文件即可,在使用的时候,引入这个接口即可,就好像使用本地类一样。 参考技术B
Java通过WSDL文件来调用webservice直接调用模式如下:
import java.util.Date;
import java.text.DateFormat;
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import javax.xml.namespace.QName;
import java.lang.Integer;
import javax.xml.rpc.ParameterMode;
public class caClient
public static void main(String[] args)
try
String endpoint = "http://localhost:8080/ca3/services/caSynrochnized?wsdl";
//直接引用远程的wsdl文件
//以下都是套路
Service service = new Service();
Call call = (Call) service.createCall();
call.setTargetEndpointAddress(endpoint);
call.setOperationName("addUser");//WSDL里面描述的接口名称
call.addParameter("userName", org.apache.axis.encoding.XMLType.XSD_DATE,
javax.xml.rpc.ParameterMode.IN);//接口的参数
call.setReturnType(org.apache.axis.encoding.XMLType.XSD_STRING);//设置返回类型
String temp = "测试人员";
String result = (String)call.invoke(new Object[]temp);
//给方法传递参数,并且调用方法
System.out.println("result is "+result);
catch (Exception e)
System.err.println(e.toString());
