Java调用天气Webservice的小应用

废话不多说,直接贴代码：

CityReq.java

package com.weather; import javax.xml.bind.annotation.XmlElement; import javax.xml.bind.annotation.XmlRootElement; @XmlRootElement(name="getWeatherbyCityName",namespace="http://WebXml.com.cn/") public class CityReq { private String theCityName; public String getTheCityName() { return theCityName; } @XmlElement(name="theCityName",namespace="http://WebXml.com.cn/") public void setTheCityName(String theCityName) { this.theCityName = theCityName; } }

WeatherWebServiceTest.java

package com.weather; import java.io.InputStream; import java.io.OutputStream; import java.net.HttpURLConnection; import java.net.URL; import javax.xml.bind.JAXBContext; import javax.xml.bind.Marshaller; import javax.xml.parsers.DocumentBuilderFactory; import javax.xml.soap.MessageFactory; import javax.xml.soap.SOAPBody; import javax.xml.soap.SOAPConstants; import javax.xml.soap.SOAPEnvelope; import javax.xml.soap.SOAPMessage; import org.w3c.dom.Document; public class WeatherWebServiceTest { public static void main(String[] args) { // TODO Auto-generated method stub weather(); } static void weather(){ System.out.println("开始登陆..."); String wsdl="http://www.webxml.com.cn/WebServices/WeatherWebService.asmx"; System.out.println("wsdl:"+wsdl); HttpURLConnection urlconn=null; InputStream ins=null; OutputStream ous=null; try { URL u=new URL(wsdl); urlconn=(HttpURLConnection)u.openConnection(); urlconn.setDoOutput(true); urlconn.setRequestMethod("POST"); urlconn.setRequestProperty("Content-Type", "application/soap+xml; charset=utf-8"); //urlconn.setRequestProperty("Content-Type", "text/xml; charset=utf-8"); //发送数据 ous=urlconn.getOutputStream(); Document document=DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument(); //编组 Marshaller marsh=JAXBContext.newInstance(CityReq.class).createMarshaller(); CityReq xmlf=new CityReq(); xmlf.setTheCityName("北京"); //JAXB.marshal(xmlf, new PrintWriter(System.out)); marsh.marshal(xmlf, document); //创建soapmessage对象 SOAPMessage soapMessage=MessageFactory.newInstance(SOAPConstants.SOAP_1_2_PROTOCOL).createMessage(); SOAPBody soapBody=soapMessage.getSOAPBody(); soapBody.addDocument(document); SOAPEnvelope soapEnvelope = soapMessage.getSOAPPart().getEnvelope(); soapEnvelope.removeNamespaceDeclaration("env"); soapEnvelope.addNamespaceDeclaration("soap12", "http://www.w3.org/2003/05/soap-envelope"); soapEnvelope.addNamespaceDeclaration("xsi", "http://www.w3.org/2001/XMLSchema-instance"); soapEnvelope.addNamespaceDeclaration("xsd", "http://www.w3.org/2001/XMLSchema"); soapEnvelope.setPrefix("soap12"); soapEnvelope.removeChild(soapEnvelope.getHeader()); soapBody.setPrefix("soap12"); //发送数据 soapMessage.writeTo(ous); // soapMessage.writeTo(System.out); System.out.println(urlconn.getResponseCode()); System.out.println(urlconn.getResponseMessage()); //接收数据 ins=urlconn.getInputStream(); //接收的数据需要解组?
