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:
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
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
Parameter soapResult = soapResponse.getReturnValue(); String[] temp = (String[])soapResult.getValue();
调用ASP.Net生成的webservice
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; } /** * 调用 C# 的webservice接口 * SoapRpcMethod(Action = "http://www.tangs.com/Add", * RequestNamespace = "http://www.tangs.com/T", * ResponseNamespace = "http://www.tangs.com/T", * Use = SoapBindingUse.Literal)] * * */ public static void addTest() { try { Integer i = 1; Integer j = 2; // WebService URL String service_url = "http://localhost:4079/ws/Service.asmx"; Service service = new Service(); Call call = (Call) service.createCall(); call.setTargetEndpointAddress(new java.net.URL(service_url)); // 设置要调用的方法 call.setOperationName(new QName("http://www.tangs.com/T", "Add")); // 该方法需要的参数 call.addParameter("a", org.apache.axis.encoding.XMLType.XSD_INT, javax.xml.rpc.ParameterMode.IN); call.addParameter("b", org.apache.axis.encoding.XMLType.XSD_INT, javax.xml.rpc.ParameterMode.IN); // 方法的返回值类型 call.setReturnType(org.apache.axis.encoding.XMLType.XSD_INT); call.setUseSOAPAction(true); call.setSOAPActionURI("http://www.tangs.com/Add"); // 调用该方法 Integer res = (Integer) call.invoke(new Object[] { i, j }); System.out.println("Result: " + res.toString()); } catch (Exception e) { System.err.println(e); } } /** * 调用 C# 的webservice接口 * SoapRpcMethod(Action = "http://www.tangs.com/Add", * RequestNamespace = "http://www.tangs.com/T", * ResponseNamespace = "http://www.tangs.com/T", * Use = SoapBindingUse.Literal)] * * */ public static void helloTest() { try { String endpoint = "http://localhost:4079/ws/Service.asmx"; Service service = new Service(); Call call = (Call) service.createCall(); call.setTargetEndpointAddress(new java.net.URL(endpoint)); call.setOperationName(new QName("http://www.tangs.com/T", "HelloWorld")); call.setUseSOAPAction(true); call.setSOAPActionURI("http://www.tangs.com/Hello"); String res = (String) call.invoke(new Object[] { null }); System.out.println("Result: " + res); } catch (Exception e) { System.err.println(e.toString()); } }
