java对接webservice接口的4种方式

本篇文章分享java对接webservice接口的4种方式，对你有帮助的话记得收藏一下，看Java资料网收获更多编程知识

一、使用httpclient的方式调用

JaxWsDynamicClientFactory factory = JaxWsDynamicClientFactory.newInstance();
        // 创建客户端连接
        Client client = factory.createClient("http://127.0.0.1:8080/xx/service/userOrg?wsdl");
        Object[] res = null;
        try {
            QName operationName = new QName("http://impl.webservice.userorg.com/","findUser");//如果有命名空间需要加上这个，第一个参数为命名空间名称，调用的方法名称
            res = client.invoke(operationName, "admin");//后面为WebService请求参数数组
            System.out.println(res[0]);
        }catch (Exception e) {
            e.printStackTrace();
        }

第二种方法

// 被<![CDATA[]]>这个标记所包含的内容将表示为纯文本 
String xmlData = "<![CDATA[<?xml version=\"1.0\" encoding=\"UTF-8\"?>" + 
"<accounts>" + 
"<account>" + 
"<accId>帐号ID(必填)</accId>" + 
"<userPasswordMD5>密码</userPasswordMD5>" + 
"<userPasswordSHA1>密码</userPasswordSHA1>" + 
"其中userPasswordSHA1标签代表SHA1加密后的密码，userPasswordMD5标签代表MD5加密后的密码" + 
"<name>姓名</name>" + 
"<sn>姓</sn>" + 
"<description>描述 </description>" + 
"<email>邮箱 </email>" + 
"<gender>性别</gender>" + 
"<telephoneNumber>电话号码</telephoneNumber>" + 
"<mobile>移动电话</mobile>" + 
"<startTime>用户的开始生效时间（YYYY-MM-DD HH:mm:SS）</startTime>" + 
"<endTime>用户结束生效时间（YYYY-MM-DD HH:mm:SS） </endTime>" + 
"<idCardNumber>身份证号码</idCardNumber>" + 
"<employeeNumber>工号 </employeeNumber>" + 
"<o>用户所属的组织的编码号 </o>" + 
"<employeeType>用户类型</employeeType>" + 
"<supporterCorpName>所在公司名称 </supporterCorpName>" + 
"</account>" + 
"</accounts>]]>";
 
//调用方法
String method = "sayHello";
   method = "getUserList";
    
String data="<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:ser=\"http://impl.webservice.platform.hotent.com/\">"+
   "<soapenv:Body>"+
      "<ser:"+method+">"+
         "<arg0>"+ xmlData + "</arg0>"+
      "</ser:"+method+">"+
   "</soapenv:Body>"+
"</soapenv:Envelope>";
String httpUrl="http://127.0.0.1:8080/xx/service/helloWorld?wsdl";
   httpUrl="http://127.0.0.1:8080/xx/service/userOrg?wsdl";
try {
//第一步：创建服务地址  
   URL url = new URL(httpUrl);  
   //第二步：打开一个通向服务地址的连接  
   HttpURLConnection connection = (HttpURLConnection) url.openConnection();  
   //第三步：设置参数  
   //3.1发送方式设置：POST必须大写  
   connection.setRequestMethod("POST");  
   //3.2设置数据格式：content-type  
   connection.setRequestProperty("content-type", "text/xml;charset=utf-8");  
   //3.3设置输入输出，因为默认新创建的connection没有读写权限，  
   connection.setDoInput(true);  
   connection.setDoOutput(true);  
 
   //第四步：组织SOAP数据，发送请求  
   String soapXML = data;
   //将信息以流的方式发送出去
   // DataOutputStream.writeBytes将字符串中的16位的unicode字符以8位的字符形式写到流里面
    
   OutputStream os = connection.getOutputStream();  
   os.write(soapXML.getBytes());  
   //第五步：接收服务端响应，打印  
   int responseCode = connection.getResponseCode();  
   System.out.println("responseCode: "+responseCode);
   if(200 == responseCode){//表示服务端响应成功  
   //获取当前连接请求返回的数据流
       InputStream is = connection.getInputStream();  
       InputStreamReader isr = new InputStreamReader(is);  
       BufferedReader br = new BufferedReader(isr);  
          
       StringBuilder sb = new StringBuilder();  
       String temp = null;  
       while(null != (temp = br.readLine())){  
           sb.append(temp);  
       }  
        
       is.close();  
       isr.close();  
       br.close(); 
       System.out.println(StringEscapeUtils.unescapeXml(sb.toString()));    //转义
       System.out.println(sb.toString());  
        
    } else { //异常信息
   InputStream is = connection.getErrorStream();    //通过getErrorStream了解错误的详情，因为错误详情也以XML格式返回，因此也可以用JDOM来获取。  
   InputStreamReader isr = new InputStreamReader(is,"utf-8");  
   BufferedReader in = new BufferedReader(isr);  
   String inputLine;  
   BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(  
           new FileOutputStream("d:\\result.xml")));// 将结果存放的位置  
   while ((inputLine = in.readLine()) != null)   
   {  
       System.out.println(inputLine);  
       bw.write(inputLine);  
       bw.newLine();  
       bw.close();  
   }  
   in.close(); 
   }
    
   os.close(); 
} catch (Exception e) {
System.out.println(e.getMessage());
}
}
 
// 把xml转义
public static String escapeXml(String xml) {
String newXml = xml.replaceAll("<", "&lt;").replaceAll(">", "&gt;").replaceAll(" ", " ").replaceAll("\"", "&quot;");
return newXml;
}

二、使用HttpURLConnection的方式调用

String url = "http://127.0.0.1/cwbase/Service/hndg/Hello.asmx?wsdl";
URL realURL = new URL(url);
HttpURLConnection connection = (HttpURLConnection) realURL.openConnection();		
		connection.setDoOutput(true);
		connection.setDoInput(true);
		connection.setRequestProperty("Content-Type", "text/xml; charset=UTF-8");
		connection.setRequestProperty("content-length", String.valueOf(xmlData.length));
		connection.setRequestMethod("POST");
DataOutputStream printOut = new DataOutputStream(connection.getOutputStream());
		printOut.write(xmlOutString.getBytes("UTF-8"));//xmlOutString是自己拼接的xml，这种方式就是通过xml请求接口
		printOut.flush();
		printOut.close();
// 从连接的输入流中取得回执信息
InputStream inputStream = connection.getInputStream();
InputStreamReader isr = new InputStreamReader(inputStream, "UTF-8");
BufferedReader bufreader = new BufferedReader(isr);
String xmlString = "";
int c;
while ((c = bufreader.read()) != -1) {
    xmlString += (char) c;
}
isr.close();
//处理返回的xml信息
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document d = db.parse(new ByteArrayInputStream(xmlString.getBytes("UTF-8")));
//从对方的节点中取的返回值（节点名由对方接口指定）
String returnState = d.getElementsByTagName("ReturnStatus").item(0).getFirstChild().getNodeValue();

三、使用AXIS调用WebService

import org.apache.axis.client.Service;
import org.apache.axis.client.Call;
import org.apache.axis.encoding.XMLType;

import javax.xml.namespace.QName;
import javax.xml.rpc.ParameterMode;


public static void main(String[] args) {
		String result = "";
		String url = "http://127.0.0.1/uapws/service/nc65to63projectsysplugin";//这是接口地址，注意去掉.wsdl，否则会报错
		Service service = new Service();
		Call call = (Call) service.createCall();
		call.setTargetEndpointAddress(url);
		String parametersName = "string";//设置参数名
		call.setOperationName("receiptProject");//设置方法名
		call.addParameter(parametersName, XMLType.XSD_STRING, ParameterMode.IN);//方法参数，1参数名、2参数类型、3.入参
		call.setReturnType(XMLType.XSD_STRING);//返回类型
		String str = json;
		Object resultObject = call.invoke(new Object[] { str });//调用接口
		result = (String) resultObject;
}

四、使用apache-cxf生成java类调用（不建议）

下载apache-cxf，并配置环境变量，详细说明，请自行学习

String result = "";
NC65To63ProjectService service = new NC65To63ProjectService();
NC65To63ProjectServicePortType servicePort = service.getNC65To63ProjectServiceSOAP11PortHttp(); 
result = servicePort.receiptProject(json);
