httpclient调用cxf开发webservice接口以及jboss开发的webservice接口

原来是用cxf直接做的webservice接口，非常简单，我的上一篇文章已经介绍过了，但是有不足之处是cxf开发的webservice接口，客户端如果也用cxf的jar去调用，

环境必须是jdk1.6或者以上版本，而客户是jdk1.5，所以换了一种方式，服务端不变，客户端用httpclient调用

1、服务端接口代码：注意http方式调用的时候，@WebParam必须写上

package com.lbs.webservice.wsinterface;import javax.jws.WebParam;import javax.jws.WebService;@WebService(name="Test12333WS")public interface Test12333WS {public Test12333Dto say(  String name);public String testRtJson(@WebParam(name="json") String json);//@WebMethod( operationName="test", action="http://wsinterface.webservice.lbs.com/") public void test();}

2、服务端实现类代码

package com.lbs.webservice.wsinterface;import java.util.ArrayList;import java.util.List;import javax.jws.WebService;import com.lbs.gioi.commonbusiness.contribution.utils.ToolsUtils;@WebServicepublic class Test12333WSIMP implements Test12333WS {@Overridepublic Test12333Dto say( String name){Test12333Dto dto = new Test12333Dto();dto.setAab001(123456L);dto.setAab002(name +"Hello World");return dto;}@Overridepublic String testRtJson(  String json) {System.out.println("传入参数是： " + json );Test12333Dto dto = new Test12333Dto();dto.setAab001(10001L);dto.setAab002("HELLO WORLD");List<Test12333Dto> dtoList = new ArrayList<Test12333Dto>();dtoList.add(dto);String rtnJson = ToolsUtils.getJsonString(dtoList) ;System.out.println(" 输出参数： " + rtnJson);return rtnJson;}public static void main(String[] args) {new Test12333WSIMP().testRtJson("{aab001:3001}");}@Overridepublic void test() {System.out.println("1234567890-------------------");}}

3、客户端代码：（这里需要引入两个jar包

1、单纯的httpclient调用webservice仅仅需要引入的包：
httpclient-4.0.1.jar, httpcore-4.0.1.jar


2、用到了json转对象需要引入的包：
commons-beanutils-1.8.0.jar
commons-collections-3.2.1.jar
commons-lang-2.5.jar
ezmorph-1.0.6.jar
json-lib-2.4-jdk15.ja）

package testhttp;import java.io.StringReader;import javax.xml.parsers.DocumentBuilder;import javax.xml.parsers.DocumentBuilderFactory;import net.sf.json.JSONArray;import net.sf.json.JSONObject;import org.apache.http.HttpEntity;import org.apache.http.HttpResponse;import org.apache.http.client.methods.HttpPost;import org.apache.http.entity.StringEntity;import org.apache.http.impl.client.DefaultHttpClient;import org.apache.http.protocol.HTTP;import org.apache.http.util.EntityUtils;import org.w3c.dom.Document;import org.w3c.dom.Element;import org.w3c.dom.Node;import org.xml.sax.InputSource;public class TestHttp {public static void main(String[] args)   {DefaultHttpClient httpClient = null;try {httpClient = new DefaultHttpClient();HttpPost httppost = new HttpPost("http://127.0.0.1:8090/gioi/services/test12333WS"); //webservice服务地址String soapRequestData = getRequestXml(); //soap协议的格式，定义了方法和参数        HttpEntity re = new StringEntity(soapRequestData,HTTP.UTF_8);        httppost.setHeader("Content-Type","application/soap+xml; charset=utf-8");          httppost.setEntity(re);         HttpResponse response = httpClient.execute(httppost); //调用接口        //输出的xml        System.out.println("httppost.getEntity() == EntityUtils.toString:   " + EntityUtils.toString(httppost.getEntity()));         //返回是否成功的状态        System.out.println(response.getStatusLine().getStatusCode());        if(response.getStatusLine().getStatusCode() == 200) {        //获得输出的字符串        String xmlString = EntityUtils.toString(response.getEntity());        String jsonString = parseXMLSTRING(xmlString);        Test12333Dto dto = jsonToObj(jsonString);        System.out.println(dto.getAab002());        }        } catch (Exception e) {e.printStackTrace();} finally {        httpClient.getConnectionManager().shutdown(); //关闭连接}        }/** * 获得请求XML * @return */private static String getRequestXml(){StringBuilder sb = new StringBuilder();sb.append("<?xml version=\"1.0\"?>");sb.append("<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" ");sb.append(" xmlns:sam=\"http://wsinterface.webservice.lbs.com/\" ");  //前缀,这一串由服务端提供sb.append(" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\"");sb.append(" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">");sb.append("<soap:Header/>");sb.append("<soap:Body>");sb.append("<sam:testRtJson>");  //“testRtJson”调用方法名sb.append("<json>老何0001</json>"); //传参,“json”是配置在服务端的参数名称，“老何0001”是要传入的参数值sb.append("</sam:testRtJson>");sb.append("</soap:Body>");sb.append("</soap:Envelope>");return sb.toString();}//解析xml文件，获取其中的返回值public  static String parseXMLSTRING(String xmlString){String returnJson = ""; try {                DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();                DocumentBuilder builder = factory.newDocumentBuilder();                Document doc = builder.parse(new InputSource(new StringReader(xmlString)));                Element root = doc.getDocumentElement();//根节点              Node node = root.getFirstChild();             while(!node.getNodeName().equals("return")) {             node = node.getFirstChild();             }             if(node.getFirstChild() != null)  returnJson = node.getFirstChild().getNodeValue();             System.out.println("获取的返回参数为：" + returnJson);         } catch (Exception e) {                e.printStackTrace();            }   return returnJson;}//转化json字符串为对象public  static Test12333Dto jsonToObj(String jsonString){Test12333Dto dto = null;JSONArray array = JSONArray.fromObject(jsonString);        for(int i = 0; i < array.size(); i++){                    JSONObject jsonObject = array.getJSONObject(i);                    dto = (Test12333Dto)JSONObject.toBean(jsonObject, Test12333Dto.class);                System.out.println(dto.getAab002());        }        return dto;}}

4、客户端的辅助dto，一般你们不需要，这只是一个举例，字段有aab002，还有很多，这里就不一一列举了

===============================================jboss===========================================================

jboss的调用方式唯一需要修改的就亮点，一点，

HttpPost httppost = new HttpPost("http://127.0.0.1:8090/gioi/services/test12333WS"); //webservice服务地址

jboss的需要在路径后加上?wsdl，即

HttpPost httppost = new HttpPost("http://127.0.0.1:8090/gioi/services/test12333WS?wsdl"); //webservice服务地址

其实httppost对应的就是发布services中的 Endpoint address:，如果没有可以去具体的路径中找到<soap:address location="http://localhost:8080/cam-jsf/ws/criminalInfo"/>

第二点

sb.append(" xmlns:sam=\"http://wsinterface.webservice.lbs.com/\" ");  //前缀,这一串由服务端提供

这里对应的就是Target namespace
Target namespace: http://outinterface.huating.com/

第三点，可能别人返回的就是xml字符串，需要转义下

 

String str = StringEscapeUtils.unescapeXml("&lt;xm&gt;位大强&lt;/xm&gt;&#xD;");

System.out.println(str);

引入的包
import org.apache.commons.lang.StringEscapeUtils;

=============================可能遇到的错误

本人遇到过一个，在main函数中运行没有问题，在tomcat下运行httpclient.execute()就报错，后面发现是jar包冲突了，有一个http-client4.0,还有一个4.3，吧4.3的删除掉即可
