Java对接WebService接口

一、使用WebClient方式实现调用；

1.WebService接口示例

POST /WebService.asmx HTTP/1.1
Host: tmscn-dev.carlsberg.asia
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://tempuri.org/GetQrCode"

<?xml version="1.0" encoding="utf-8"?>
<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/">
  <soap:Header>
    <WSAuthentication xmlns="http://tempuri.org/">
      <UserName>string</UserName>
      <Password>string</Password>
    </WSAuthentication>
  </soap:Header>
  <soap:Body>
    <GetQrCode xmlns="http://tempuri.org/">
      <BeginDate>string</BeginDate>
      <EndDate>string</EndDate>
    </GetQrCode>
  </soap:Body>
</soap:Envelope>
HTTP/1.1 200 OK
Content-Type: text/xml; charset=utf-8
Content-Length: length

<?xml version="1.0" encoding="utf-8"?>
<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/">
  <soap:Body>
    <GetQrCodeResponse xmlns="http://tempuri.org/">
      <GetQrCodeResult>string</GetQrCodeResult>
    </GetQrCodeResponse>
  </soap:Body>
</soap:Envelope>

2.代码如下：

package com.sigmatrix.utils;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;

@Component
public class WebServiceUtils { 
   

    private static Logger logger = LoggerFactory.getLogger(WebServiceUtils.class);

    private static String qrCodeUrl = https://tmscn-dev.carlsberg.asia:8443/WebService.asmx

    /** * 请求头 * @return */
    public static String getSoapHeader(String userName, String passWord){ 
   
        StringBuffer soapHeader = new StringBuffer();
        soapHeader.append("<soap:Header>");
        soapHeader.append("<WSAuthentication xmlns=\"http://tempuri.org/\">");
        soapHeader.append("<UserName>"+userName+"</UserName>");
        soapHeader.append("<Password>"+passWord+"</Password>");
        soapHeader.append("</WSAuthentication>");
        soapHeader.append("</soap:Header>");
        return soapHeader.toString();
    }

    /** * 请求体 * @return */
    public static String getAccInfoXml(String userName, String passWord, String beginDate, String endDate){ 
   
        StringBuffer template = new StringBuffer();
        String header = getSoapHeader(userName, passWord);
        template.append("<?xml version=\"1.0\" encoding=\"utf-8\"?><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/\">");
        template.append(header);
        template.append("<soap:Body>");
        template.append("<GetQrCode xmlns=\"http://tempuri.org/\">");
        template.append("<BeginDate>"+beginDate+"</BeginDate>");
        template.append("<EndDate>"+endDate+"</EndDate>");
        template.append("</GetQrCode>");
        template.append("</soap:Body>");
        template.append("</soap:Envelope>");
        return template.toString();
    }

    /** * 访问WebService接口，获取数据 * @return */
    public static String getAccInfo(String userName, String passWord, String beginDate, String endDate){ 
   
        String urlStr = qrCodeUrl;
        String paraXml = getAccInfoXml(userName, passWord, beginDate, endDate);
        String soapAction ="http://tempuri.org/GetQrCode";
        OutputStream out = null;
        String resultData = "";
        try { 
   
            URL url = new URL(urlStr);
            HttpURLConnection con;
            con = (HttpURLConnection) url.openConnection();
            con.setDoOutput(true);
            con.setDoInput(true);
            con.setRequestMethod("POST");
            con.setUseCaches(false);
            con.setRequestProperty("Content-type", "text/xml; charset=UTF-8");
            con.setRequestProperty("SOAPAction", soapAction);
            out = con.getOutputStream();
            con.getOutputStream().write(paraXml.getBytes());
            out.flush();
            out.close();
            int code = con.getResponseCode();
            String tempString = null;
            StringBuffer sb1 = new StringBuffer();
            if (code == HttpURLConnection.HTTP_OK) { 
   
                BufferedReader reader = new BufferedReader(new InputStreamReader(con.getInputStream(), "UTF-8"));
                while ((tempString = reader.readLine()) != null) { 
   
                    sb1.append(tempString);
                }
                if (null != reader) { 
   
                    reader.close();
                }
            } else { 
   
                BufferedReader reader = new BufferedReader(new InputStreamReader(con.getErrorStream(), "UTF-8"));
                // 一次读入一行，直到读入null为文件结束
                while ((tempString = reader.readLine()) != null) { 
   
                    sb1.append(tempString);
                }
                if (null != reader) { 
   
                    reader.close();
                }
            }
            //响应报文
            resultData =  sb1.toString();
            System.out.println(resultData);

        } catch (Exception e) { 
   
            logger.error("访问webService接口异常", e);
        }
        return resultData;
    }
}

二、根据wsdl文件来生成java-ws调用WebService接口

1.在cmd中执行以下命令，在指定目录中自动生成代码，调用webservice接口。

wsimport -XadditionalHeaders -s d:\webservice2 -p com.example.demo.request -encoding utf-8 https://tmscn-dev.carlsberg.asia:8443/WebService.asmx?WSDL

三、根据WebService完整的访问路径和用户密码生成代码

1.创建java项目；
2.添加框架依赖

3.选择webservices client

4.使用idea生成相关代码


5.客户端测试

自动生成的是lib包，相对应的pom依赖
