通过配置spring.xml实现通用Webservice调用

写一个第三方服务调用通用类，把Axis参数作为属性定义在类中：

import java.net.MalformedURLException;import java.net.URL;import java.rmi.RemoteException;import java.util.Iterator;import java.util.Map;import java.util.Set;import javax.xml.namespace.QName;import javax.xml.rpc.ServiceException;import org.apache.axis.AxisProperties;import org.apache.axis.client.Call;import org.apache.axis.client.Service;package jastar.test;public class ThirdPartyService {private String endpoint; // 服务端点private String namespace; // 命名空间private String operationName; // 服务操作名称private QName returnType; // 服务获取的对象类型名称private Map<String, String> params; // 传入参数名称和类型对/** * 调用Web service并返回返回结果 *  * @param args 传入的参数对象数组 * @return WebServices 调用结果 * @throws RepairServiceException  */public Object getCallResult(Object[] args) throws RepairServiceException {AxisProperties.setProperty("http.proxyHost","192.168.1.22");AxisProperties.setProperty("http.proxyPort","808");Object ret = null;Service service = new Service();QName qn = new QName(namespace, operationName);Call call = null;try {call = (Call)service.createCall();} catch (ServiceException e) {throw new MyServiceException("创建Webservice调用对象失败！", e);}call.setOperationName(qn);Set<String> keys = params.keySet();for (Iterator<String> it = keys.iterator(); it.hasNext();) {String paramName = it.next();QName param = new QName(namespace, paramName);QName xmlType =new QName(namespace, (String)params.get(paramName));call.addParameter(param, xmlType,javax.xml.rpc.ParameterMode.IN);}try {call.setTargetEndpointAddress(new URL(endpoint));} catch (MalformedURLException e) {throw new MyServiceException("设置Service服务端失败！", e);}call.setReturnType(returnType);try {ret = call.invoke(args);} catch (RemoteException e) {throw new MyServiceException("调用WebService服务失败！", e);}return ret;}public String getEndpoint() {return endpoint;}public void setEndpoint(String endpoint) {this.endpoint = endpoint;}public String getNamespace() {return namespace;}public void setNamespace(String namespace) {this.namespace = namespace;}public String getOperationName() {return operationName;}public void setOperationName(String operationName) {this.operationName = operationName;}public QName getReturnType() {return returnType;}public void setReturnType(QName returnType) {this.returnType = returnType;}public Map getParams() {return params;}@SuppressWarnings ("unchecked")public void setParams(Map params) {this.params = params;}}

将这个ThirdPartService类注入到具体的业务Service中，在具体业务方法中调用ThirdPartyService的getCallResult，从而可以将第三方服务调用方便的封装起来。

在applicationContext.xml中配置服务调用相关参数：

<bean id="helloSupportService"class="jastar.HelloSupportService"><property name="gisSupportService"><beanclass="jastar.ThirdPartySupportService"><property name="endpoint"><value>http://192.168.1.1:8080/Service.asmx</value></property><property name="namespace"><value>http://service.jastar</value></property><property name="operationName"><value>sayHello</value></property><property name="returnType"><util:constantstatic-field="org.apache.axis.encoding.XMLType.SOAP_STRING" /></property><property name="params"><map><entry key="name" value="string" /><entry key="greeting" value="string" /></map></property></bean></property></bean>
