调用webservice,可以首先根据wsdl文件生成客户端,或者直接根据地址调用,下面讨论直接调用地址的两种不同方式:axis和Soap,soap方式主要是用在websphere下
soap方式调用
调用java生成的webservice (Java代码 )
返回一维数组时 (Java代码)
调用ASP.Net生成的webservice (Java代码)
调用webservice,可以首先根据wsdl文件生成客户端,或者直接根据地址调用,下面讨论直接调用地址的两种不同方式:axis和Soap,soap方式主要是用在websphere下
axis方式调用(Java代码):
- 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";
- Service service = new Service();
- Call call = (Call) service.createCall();
- call.setTargetEndpointAddress(endpoint);
- call.setOperationName("addUser");
- call.addParameter("userName", org.apache.axis.encoding.XMLType.XSD_DATE,
- javax.xml.rpc.ParameterMode.IN);
- call.setReturnType(org.apache.axis.encoding.XMLType.XSD_STRING);
- call.setUseSOAPAction(true);
- call.setSOAPActionURI("http://www.my.com/Rpc");
- //Integer k = (Integer) call.invoke(new Object[] { i, j });
- //System.out.println("result is " + k.toString() + ".");
- String temp = "测试人员";
- String result = (String)call.invoke(new Object[]{temp});
- System.out.println("result is "+result);
- }
- catch (Exception e) {
- System.err.println(e.toString());
- }
- }
- }
soap方式调用
调用java生成的webservice (Java代码 )
- 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();
- }
- }
- }
返回一维数组时 (Java代码)
- Parameter soapResult = soapResponse.getReturnValue();
- String[] temp = (String[])soapResult.getValue();
调用ASP.Net生成的webservice (Java代码)
- private String HelloWorld(String uri, String u) {
- try {
- SOAPMappingRegistry smr = new SOAPMappingRegistry();
- StringDeserializer sd = new StringDeserializer();
- ArraySerializer arraySer = new ArraySerializer();
- BeanSerializer beanSer = new BeanSerializer();
- smr.mapTypes(Constants.NS_URI_SOAP_ENC, new QName(
- "http://tempuri.org/", "HelloWorldResult"), String.class,
- null, sd);
- smr.mapTypes(Constants.NS_URI_SOAP_ENC, new QName(
- "http://tempuri.org/", "temp"), String.class,
- beanSer, beanSer);
- URL url = new URL(uri);
- Call call = new Call();
- call.setSOAPMappingRegistry(smr);
- call.setTargetObjectURI("urn:xmethods-Service1");
- call.setMethodName("HelloWorld");
- call.setEncodingStyleURI(Constants.NS_URI_SOAP_ENC);
- Vector soapParams = new Vector();
- soapParams.addElement(new Parameter("temp", String.class, u, null));
- call.setParams(soapParams);
- Response soapResponse = call.invoke(url,"http://tempuri.org/HelloWorld");
- if (soapResponse.generatedFault()) {
- Fault fault = soapResponse.getFault();
- System.out.println(fault);
- } else {
- Parameter soapResult = soapResponse.getReturnValue();
- Object obj = soapResult.getValue();
- System.out.println("===" + obj);
- }
- } catch (Exception e) {
- e.printStackTrace();
- }
- return null;
- }
