java 实现WebService 以及不同的调用方式webservice:
package com.webservcie; import javax.jws.WebMethod; import javax.jws.WebParam; import javax.jws.WebResult; import javax.jws.WebService; import javax.xml.ws.Endpoint; /** * WebService * 将 Java 类标记为实现 Web Service,或者将 Java 接口标记为定义 Web Service 接口 */ @WebService(serviceName="MyService",targetNamespace="http://www.baidu.com") public class HelloService { @WebMethod(operationName="AliassayHello") @WebResult(name="myReturn") public String sayHello(@WebParam(name="name") String name){ return "hello: " + name; } public String sayGoodbye(String name){ return "goodbye: " + name; } @WebMethod(exclude=true)//当前方法不被发布出去 public String sayHello2(String name){ return "hello " + name; } public static void main(String[] args) { /** * 参数1:服务的发布地址 * 参数2:服务的实现者 * Endpoint 会重新启动一个线程 */ Endpoint.publish("http:///", new HelloService()); System.out.println("Server ready..."); } }
1.客户端调用(wximport自动生成代码 【推荐】) package com.wsclient; public class App { /** * 通过wsimport 解析wsdl生成客户端代码调用WebService服务 * * @param args * */ public static void main(String[] args) { // TODO Auto-generated method stub /** * <service name="MyService"> * 获得服务名称 */ MyService mywebService = new MyService(); /** * <port name="HelloServicePort" binding="tns:HelloServicePortBinding"> */ HelloService hs = mywebService.getHelloServicePort(); /** * 调用方法 */ System.out.println(hs.sayGoodbye("sjk")); System.out.println(hs.aliassayHello("sjk")); } } 2.通过ajax+js+xml调用 <html> <head> <title>通过ajax调用WebService服务</title> <script> var xhr = new ActiveXObject("Microsoft.XMLHTTP"); function sendMsg(){ var name = document.getElementById('name').value; //服务的地址 var wsUrl = 'http://192.168.1.100:6789/hello'; //请求体 var soap = '<soapenv:Envelope xmlns:soapenv="http://schemas./soap/envelope/" xmlns:q0="http://ws./" xmlns:xsd="http://www./2001/XMLSchema" xmlns:xsi="http://www./2001/XMLSchema-instance">' + ' <soapenv:Body> <q0:sayHello><arg0>'+name+'</arg0> </q0:sayHello> </soapenv:Body> </soapenv:Envelope>'; //打开连接 xhr.open('POST',wsUrl,true); //重新设置请求头 xhr.setRequestHeader("Content-Type","text/xml;charset=UTF-8"); //设置回调函数 xhr.onreadystatechange = _back; //发送请求 xhr.send(soap); } function _back(){ if(xhr.readyState == 4){ if(xhr.status == 200){ //alert('调用Webservice成功了'); var ret = xhr.responseXML; var msg = ret.getElementsByTagName('return')[0]; document.getElementById('showInfo').innerHTML = msg.text; //alert(msg.text); } } } </script> </head> <body> <input type="button" value="发送SOAP请求" onclick="sendMsg();"> <input type="text" id="name"> <div id="showInfo"> </div> </body> </html>
3.URL Connection方式 import java.io.InputStream; import java.io.OutputStream; import java.net.HttpURLConnection; import java.net.URL; /** * 通过UrlConnection调用Webservice服务 * */ public class App { public static void main(String[] args) throws Exception { //服务的地址 URL wsUrl = new URL("http://192.168.1.100:6789/hello"); HttpURLConnection conn = (HttpURLConnection) wsUrl.openConnection(); conn.setDoInput(true); conn.setDoOutput(true); conn.setRequestMethod("POST"); conn.setRequestProperty("Content-Type", "text/xml;charset=UTF-8"); OutputStream os = conn.getOutputStream(); //请求体 String soap = "<soapenv:Envelope xmlns:soapenv=\"http://schemas./soap/envelope/\" xmlns:q0=\"http://ws./\" xmlns:xsd=\"http://www./2001/XMLSchema\" xmlns:xsi=\"http://www./2001/XMLSchema-instance\">" + "<soapenv:Body> <q0:sayHello><arg0>aaa</arg0> </q0:sayHello> </soapenv:Body> </soapenv:Envelope>"; os.write(soap.getBytes()); InputStream is = conn.getInputStream(); byte[] b = new byte[1024]; int len = 0; String s = ""; while((len = is.read(b)) != -1){ String ss = new String(b,0,len,"UTF-8"); s += ss; } System.out.println(s); is.close(); os.close(); conn.disconnect(); } }
4.客户单编程方式(和第一种方式一样) //文件名:HelloService.java
import java.net.MalformedURLException; import java.net.URL; import javax.xml.namespace.QName; import javax.xml.ws.Service; import cn.itcast.ws.wsimport.HelloService; /** * 通过客户端编程的方式调用Webservice服务 * */ public class App { public static void main(String[] args) throws Exception { URL wsdlUrl = new URL("http://192.168.1.100:6789/hello?wsdl"); Service s = Service.create(wsdlUrl, new QName("http://ws./","HelloServiceService")); HelloService hs = s.getPort(new QName("http://ws./","HelloServicePort"), HelloService.class); String ret = hs.sayHello("zhangsan"); System.out.println(ret); } }
