WSDL WebService的创建和使用实例
一. WSDL WebService的创建：
1.创建【Web Service Project】：
WebServices Framework要选JAX-WS：
2.写一个简单的测试用例：
package com.webservice;
public class WebService{
public String printData(String printerName){
String strRet = "Welcome to use WebService, " + printerName;
System.out.println("Print from WebService:" + strRet);
return strRet;
}
}3.发布Web Service：
点击工具栏的New Web Service：
Strategy选择第二个（Create web service from Java class）：
勾选【Generate WSDL in project】：
点击【Finish】后，系统会在WEB-INF/wsdl下生成两个文件：
WebServiceService.wsdl：这个文件是用来描述Web Service内容的
WebServiceService_schema1.xsd：用来说明Web Service的命令及其参数
比如：sample里面的WebService是【printData】,有一个String类型的参数【arg0】，返回值一个String类型的值。
将WebService项目部署到Tomcat即可。
（部署方法略）
二. WSDL WebService的调用：
方法1：创建Web Service Client来调用：
1.创建【Java Project】：
2. 点击工具栏的New Web Service Client：
3.选择【WSDL URL】：
4.点击【Next】完成创建后，在src/com/webservice下，自动生成相关文件。（WebServiceTest.java除外，这个是自己创建的调用文件）
5.创建【WebServiceTest.java】
代码如下：
package com.webservice;
public class WebServiceTest{
public static void main(String[] args){
WebServiceService wssPrintData = new WebServiceService();
WebServiceDelegate wsdPrintData = wssPrintData.getWebServicePort();
System.out.println(wsdPrintData.printData("sun"));
}
}6.【WebServiceTest.java】右键→Run As→Java Application
输出结果：
Welcome to use WebService, sun
方法2：用HttpClient调用：
package com.httpclientforwsdl;
import java.io.ByteArrayInputStream;
import java.io.InputStream;
import java.util.HashMap;
import java.util.Iterator;
import java.util.Map;
import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.methods.InputStreamRequestEntity;
import org.apache.commons.httpclient.methods.PostMethod;
import org.apache.commons.httpclient.methods.RequestEntity;
public class WebServiceHttpClientTest{
public synchronized static String accessService(String wsdl,String ns,String method,Map params,String result)throws Exception{
//拼接参数
String param = getParam(params);
String soapResponseData = "";
//拼接SOAP
StringBuffer soapRequestData = new StringBuffer("");
soapRequestData.append("");
soapRequestData.append("");
soapRequestData.append("");
soapRequestData.append(param);
soapRequestData.append(" ");
soapRequestData.append(" " + " ");
PostMethod postMethod = new PostMethod(wsdl);
// 然后把Soap请求数据添加到PostMethod中
byte[] b=null;
InputStream is=null;
try {
b = soapRequestData.toString().getBytes("utf-8");
is = new ByteArrayInputStream(b, 0, b.length);
RequestEntity re = new InputStreamRequestEntity(is, b.length,"text/xml; charset=UTF-8");
postMethod.setRequestEntity(re);
HttpClient httpClient = new HttpClient();
int status = httpClient.executeMethod(postMethod);
System.out.println("status:"+status);
if(status==200){
soapResponseData = getMesage(postMethod.getResponseBodyAsString(),result);
}
} catch (Exception e) {
e.printStackTrace();
} finally{
if(is!=null){
is.close();
}
}
return soapResponseData;
}
public static String getParam(Map params){
String param = "";
if(params!=null){
Iterator it = params.keySet().iterator();
while(it.hasNext()){
String str = it.next();
param+="<"+str+">";
param+=params.get(str);
param+="";
}
}
return param;
}
public static String getMesage(String soapAttachment,String result){
System.out.println("message:"+soapAttachment);
if(result==null){
return null;
}
if(soapAttachment!=null && soapAttachment.length()>0){
int begin = soapAttachment.indexOf(result);
begin = soapAttachment.indexOf(">", begin);
int end = soapAttachment.indexOf("");
String str = soapAttachment.substring(begin+1, end);
str = str.replaceAll("<", "<");
str = str.replaceAll(">", ">");
return str;
}else{
return "";
}
}
/**
* @param args
*/
public static void main(String[] args) {
try {
Map param = new HashMap();
param.put("arg0", "sun");
String wsdl="http://localhost:8080/WebService/WebServicePort?wsdl";
String ns = "http://webservice.com/";
String method="printData";
String response =accessService(wsdl,ns,method,param,"return");
System.out.println("main:"+response);
} catch (Exception e) {
e.printStackTrace();
}
}
} 显示结果：
status:200

警告: Going to buffer response body of large or unknown size. Using getResponseBodyAsStream instead is recommended.
