java调用webservice服务详细案例一

一、用到的依赖包（可以在mevan中央仓库自行下载 https://mvnrepository.com/）

    
        wsdl4j
        wsdl4j
        1.6.3
    
    
    
        org.apache.axis
        axis
        1.4
    
    
    
      org.dom4j
      dom4j
      2.1.1
    

二、需求描述*
通过java程序远程访问地方服务提供的webservice服务，调用是参数四个入参
由于xml消息没有格式化，为了调用及后续日志清晰，所以在调用前，首先判断了该字符串是不是xml，如是则格式化成标准xml消息体，主要为了提高日志消息的可阅读性

三、代码样例：

package cn.tx.webservice;


import org.apache.axis.client.Service;
import org.apache.axis.encoding.XMLType;
import javax.xml.namespace.QName;
import org.apache.axis.client.Call;
import org.apache.axis.handlers.soap.SOAPService;


import org.dom4j.*;
import org.dom4j.io.OutputFormat;
import org.dom4j.io.XMLWriter;
import org.xml.sax.InputSource;
import javax.xml.parsers.documentBuilder;
import javax.xml.parsers.documentBuilderFactory;
import javax.xml.rpc.ParameterMode;
import javax.xml.rpc.ServiceException;
import java.io.StringReader;
import java.io.StringWriter;
import java.rmi.RemoteException;




public class SendSynyiPatientCardAdd {
    //设置访问wsdl服务地址
    private final String url="http://100.89.xx.xx:22002/services/HIS?wsdl";
    //命名空间
    private final  String namespace="www.xxx.com";
    //具体方法
    private final  String method="invoke";
    //设置接口名称
    private  final String soapAction="H";
    
    public  String sendPatientAdd(String services,String urid,String pwd,String parameter) throws ServiceException, ServiceException, RemoteException {
        Service  service=new Service();
        Call call = (Call) service.createCall();
        call.setTargetEndpointAddress(url);//设置请求wsdl
        call.setOperationName(new QName(namespace,method)); //设置请求命名空s间及具体方法
        //设置入参
        call.addParameter("services", XMLType.XSD_STRING, ParameterMode.IN);//设置请求参数1
        call.addParameter("urid", XMLType.XSD_STRING, ParameterMode.IN);//设置请求参数2
        call.addParameter("pwd", XMLType.XSD_STRING, ParameterMode.IN);//设置请求参数3
        call.addParameter("parameter", XMLType.XSD_STRING, ParameterMode.IN);//设置请求参数4
        call.setUseSOAPAction(true);  //设置使用soap操作
        call.setTimeout(6000); //设置超时时间
        call.setReturnType(XMLType.XSD_STRING);//设置返回类型

        SOAPService soapService=new SOAPService();
        soapService.setName(soapAction);
        call.setSOAPService(soapService);
        Object[] obj = { services, urid, pwd,parameter};  //将所需要传过去的四个参数放在数据组内
        String invoke = (String)call.invoke(obj);//调用并将返回强转字符串
        return invoke;
    }

    public static void main(String[] args) throws Exception {
        SendSynyiPatientCardAdd  send=new SendSynyiPatientCardAdd();
        String  xml="";  //需自定义参数
        String isxml = formatXml(xml);//将消息格式化xml

        String st = send.sendPatientAdd("PatientCardUpdate", "H", "h", isxml);
        String responseXml = formatXml(st);//将返回消息格式化xml
        System.out.println(responseXml);

    }

    //判断字符串是否符合xml格式要求
    public static boolean isXmldocument(String xml){
        boolean isxml=true;
        documentBuilderFactory documentBuilderFactory = documentBuilderFactory.newInstance();
        documentBuilder documentBuilder=null;
        try {
            documentBuilder= documentBuilderFactory.newdocumentBuilder();
            documentBuilder.parse(new InputSource(new StringReader(xml)));
        } catch (Exception e) {
            isxml=false;
        }
        return  isxml;
    }


    //将字符串字符串的xml 进行格式化
    public  static String  formatXml(String xml) throws Exception {
        boolean isxml = isXmldocument(xml);
        if(isxml==false){
            return "is not xml";
        }
        org.dom4j.document  document= documentHelper.parseText(xml);
        OutputFormat outputFormat=OutputFormat.createPrettyPrint();
        outputFormat.setEncoding("UTF-8");
        StringWriter  stringWriter=new StringWriter();
        //格式化输出
        XMLWriter xmlWriter=new XMLWriter(stringWriter,outputFormat);
        xmlWriter.write(document);
        return stringWriter.toString();
    }
