java调用.net asmx服务

Posted 2020-06-08

有时候，在java下开发会调用一下.net下写的服务，看网上有各种方法，但总是不成功，总结下自己测试过能调用成功的方式：

1. 原始方式http-soap

public static String postWs() throws IOException {
        OutputStreamWriter out = null;
        StringBuilder sTotalString = new StringBuilder();
        String soapStr=genSoapXml();
        try {
            URL urlTemp = new URL("http://10.6.54.238:8005/SendMessageService.asmx");
            HttpURLConnection connection = (HttpURLConnection)urlTemp.openConnection();
            connection.setDoOutput(true);
            connection.setRequestMethod("POST");
            //connection.setRequestProperty("Host", "10.6.54.238");
            connection.setRequestProperty("Content-Type", "text/xml; charset=utf-8");
            //connection.setRequestProperty("Content-Length", Integer.toString(soapStr.length()));
            connection.setRequestProperty("SOAPAction","http://ilink.***.com.cn/SendMessage");

            out = new OutputStreamWriter(connection.getOutputStream(), "UTF-8");
            out.write(soapStr);
            out.flush();

            String sCurrentLine;
            InputStream l_urlStream= connection.getInputStream();
            BufferedReader l_reader = new BufferedReader(new InputStreamReader(l_urlStream));
            while ((sCurrentLine = l_reader.readLine()) != null) {
                sTotalString.append(sCurrentLine);
            }

        } finally {
            if (null != out) {
                try {
                    out.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
        return sTotalString.toString();
}

static String genSoapXml(){
        /*String str="<?xml version=\"1.0\" encoding=\"utf-8\"?>\n" +
                "<soap12:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap12=\"http://www.w3.org/2003/05/soap-envelope\">\n" +
                "  <soap12:Body>\n" +
                "    <SendMessage xmlns=\"http://ilink.***.com.cn/\">\n" +
                "      <strRequest></strRequest>\n" +
                "    </SendMessage>\n" +
                "  </soap12:Body>\n" +
                "</soap12:Envelope>";*/
        StringBuilder sb=new StringBuilder();
        sb.append("<?xml version=\"1.0\" encoding=\"utf-8\"?>");
        sb.append("<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">" );
        sb.append("<soap:Body>");
        sb.append("<SendMessage xmlns=\"http://ilink.***.com.cn/\">");
        sb.append("<strRequest><![CDATA["+genReq()+"]]></strRequest>" );
        sb.append("</SendMessage>" );
        sb.append("</soap:Body>" );
        sb.append("</soap:Envelope>");
        return sb.toString();
    }

红色斜体部分是调用方法和参数

 

2. 使用apache axis,看起来特优雅

添加maven依赖

<dependency>
　　<groupId>org.apache.axis</groupId>
   <artifactId>axis</artifactId>
   <version>1.4</version>
</dependency>

        <dependency>
           <groupId>org.apache.axis</groupId>
           <artifactId>axis-jaxrpc</artifactId>
            <version>1.4</version>
        </dependency>

        <dependency>
            <groupId>wsdl4j</groupId>
            <artifactId>wsdl4j</artifactId>
            <version>1.6.3</version>
        </dependency>

        <dependency>
            <groupId>commons-discovery</groupId>
            <artifactId>commons-discovery</artifactId>
            <version>0.5</version>
        </dependency>

 

public static void testAsmx() throws RemoteException, ServiceException, MalformedURLException {

        Map<String, String> params = new HashMap<String, String>();
        params.put("strRequest", genReq());

        String result = callAsmxWebService("http://10.6.54.238:8005/SendMessageService.asmx", "http://ilink.***.com.cn/", "SendMessage", params);
        logger.error("asmx:"+result);
    }

    static String callAsmxWebService(String serviceUrl, String serviceNamespace,
                              String methodName, Map<String, String> params) throws ServiceException, MalformedURLException, RemoteException {

        org.apache.axis.client.Service service = new org.apache.axis.client.Service();
        Call call = (Call) service.createCall();
        call.setTargetEndpointAddress(new java.net.URL(serviceUrl));
        call.setOperationName(new QName(serviceNamespace,methodName));

        ArrayList<String> paramValues = new ArrayList<String>();
        for (Map.Entry<String, String> entry : params.entrySet()) {
            call.addParameter(new QName(serviceNamespace, entry.getKey()),
                    XMLType.XSD_STRING, javax.xml.rpc.ParameterMode.IN);
            paramValues.add(entry.getValue());
        }

        call.setReturnType(XMLType.XSD_STRING);
        call.setUseSOAPAction(true);
        call.setSOAPActionURI(serviceNamespace + methodName);

        return (String) call.invoke(new Object[] { paramValues.toArray() });

    }

 

3. 使用httpclient4.5.jar，也是post soap xml

public static String testWs() throws IOException {
        String serviceUrl = "http://10.6.54.238:8005/SendMessageService.asmx";

        HttpClient client = new DefaultHttpClient();
        HttpPost httpPost = new HttpPost(serviceUrl);

        String str=genSoapXml();

        httpPost.setEntity(new StringEntity(str, "text/xml;", HTTP.UTF_8));
        HttpResponse httpResponse = client.execute(httpPost);

        int code=httpResponse.getStatusLine().getStatusCode();

　　　　 if(200 ==code){
        　　HttpEntity entity = httpResponse.getEntity();
        　　InputStream inputStream = entity.getContent();
        　　byte[] contentBytes = IOUtils.toByteArray(inputStream);
        　　String res = new String(contentBytes, HTTP.UTF_8);
　　　　　　 inputStream.close();
　　　　　　 return res;

　　　　 }
　　　　 return null;
    }
