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：
