鉴于CXF框架的web service学习，传递xml,json并解析,容易上手

所依赖的jar包：apache-cxf-2.7.10，可以再官网下载，还有json.rar的对应包，联系是一个java 项目

一：下载对应Jar,可以在官网下载，或是到我资源下载，里面jar都齐全了,将apache-cxf-2.7.10下面的Lib中的jar加入项目中

二：.编写web services的服务端：需要一个接口，叫做Hello,代码如下：在类名称前加入@WebService注释

package com;import javax.jws.WebService;import net.sf.json.JSONObject;@WebServicepublic interface Hello {public String sayHello(String str);public JSONObject sayJson(String str);public String sayJsonStr(String str);}

三：编写接口实现类:包括传递的两种参数，一种是拼接的xml字符串，一种是json的对象

package com;import java.util.HashMap;import java.util.Map;import net.sf.json.JSONObject;public class HelloImpl implements Hello {@Overridepublic String sayHello(String str) {System.out.println("web services调用成功");String result = createXml(str);return result;}public static void main(String[] args) throws Exception {JSONObject jsonObj = new JSONObject();jsonObj.put("name", "liqineng");String[] likes = new String[] { "music", "movie", "study" };jsonObj.put("hobby", likes);Map<String, String> ingredients = new HashMap<String, String>();ingredients.put("age", "23");ingredients.put("EnglishName", "spider man");ingredients.put("sex", "boy");ingredients.put("love", "tangwei");jsonObj.put("message", ingredients);System.out.println(jsonObj);}/** * 创建JsonOBject对象 *  * @param 客户端传递的参数Name * @return 返回jsonObject对象 */public JSONObject createJsonObject(String name) {JSONObject jsonObj = new JSONObject();jsonObj.put("name", "liqineng");String[] likes = new String[] { "music", "movie", "study" };jsonObj.put("hobby", likes);Map<String, String> ingredients = new HashMap<String, String>();ingredients.put("age", "23");ingredients.put("EnglishName", "spider man");ingredients.put("sex", "boy");ingredients.put("love", "tangwei");jsonObj.put("message", ingredients);return jsonObj;}/** * 根据传递的字符串生成对应的xml。 *  * @param 传递过来的参数name * @return 返回xml的字符串 */public String createXml(String name) {StringBuffer sb = new StringBuffer();sb.append("<?xml version='1.0' encoding='UTF-8'?>");sb.append("<Result>");sb.append("<cinamaName>机械战警</cinamaName>");sb.append("<director>" + name + "</director>");sb.append("<introduce>一部好莱坞大片，3D观影，不错！！！</introduce>");sb.append("<price>25</price>");sb.append("</Result>");return sb.toString();}@Overridepublic JSONObject sayJson(String str) {return createJsonObject(str);}@Overridepublic String sayJsonStr(String str) {return createJsonObject(str).toString();}}

四：编写web services的启动类，代码如下，运行，web services即可查询了：

package com;import org.apache.cxf.endpoint.Server;import org.apache.cxf.jaxws.JaxWsServerFactoryBean;public class MainServer {public static void main(String[] args) {JaxWsServerFactoryBean factory = new JaxWsServerFactoryBean();factory.setAddress("http://192.168.10.197:8080/cxf");factory.setServiceClass(HelloImpl.class);Server server = factory.create();server.start();}}

然后可以输入：http://192.168.10.197:8080/cxf?wsdl 在浏览器上进行查看，你可以可以下载一个soapUi进行专业的测试

第五：编写Webservice的客户端：如果不在同一个项目中的话，同样也需要下载对应的jar包文件，

需要创建一个接口，接口也是方法，注意:方法也需要添加@WebService注释，代码如下：

package com;import javax.jws.WebService;import net.sf.json.JSONObject;@WebServicepublic interface Hello {public String sayHello(String str);public JSONObject sayJson(String str);public String sayJsonStr(String str);}

主的接收和解析类：包括xml解析，json的解析：

package com;import java.io.FileNotFoundException;import java.io.IOException;import java.io.StringReader;import javax.xml.parsers.DocumentBuilder;import javax.xml.parsers.DocumentBuilderFactory;import javax.xml.parsers.ParserConfigurationException;import net.sf.json.JSONObject;import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;import org.w3c.dom.Document;import org.w3c.dom.Node;import org.w3c.dom.NodeList;import org.xml.sax.InputSource;import org.xml.sax.SAXException;/** * 客户端调用类。 *  *  */public class Client {public static void main(String[] args) {JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();factory.setServiceClass(Hello.class);factory.setAddress("http://192.168.10.197:8080/cxf?wsdl");Hello hello = (Hello) factory.create();String xml = hello.sayHello("zhangsan");// JSONObject obj = hello.sayJson("liqineng");// parserXml(xml);String str = hello.sayJsonStr("liqineng");ParseJsonStr(str);// System.out.println(xml);}/** * 解析xml字符串 *  * @param str传递过来的xml字符串 */public static void parserXml(String str) {try {StringReader read = new StringReader(str);// 创建新的输入源SAX 解析器将使用 InputSource 对象来确定如何读取 XML 输入InputSource source = new InputSource(read);// 创建一个新的SAXBuilderDocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();DocumentBuilder db = dbf.newDocumentBuilder();Document document = db.parse(source);NodeList movies = document.getChildNodes();for (int i = 0; i < movies.getLength(); i++) {Node employee = movies.item(i);NodeList employeeInfo = employee.getChildNodes();for (int j = 0; j < employeeInfo.getLength(); j++) {Node node = employeeInfo.item(j);if (node.getNodeType() == Node.ELEMENT_NODE) {if ("cinamaName".equals(node.getNodeName())) {System.out.println("电影名称:" + node.getTextContent());} else if ("introduce".equals(node.getNodeName())) {System.out.println("电影简介:" + node.getTextContent());} else if ("price".equals(node.getNodeName())) {System.out.println("电影价格:" + node.getTextContent());} else if ("director".equals(node.getNodeName())) {System.out.println("导演:" + node.getTextContent());}}}}} catch (FileNotFoundException e) {System.out.println(e.getMessage());} catch (ParserConfigurationException e) {System.out.println(e.getMessage());} catch (SAXException e) {System.out.println(e.getMessage());} catch (IOException e) {System.out.println(e.getMessage());}}public static void ParseJsonObject(JSONObject obj) {System.out.println(obj);String name = obj.getString("name");}/** * 解析json字符串 *  * @param str传递过来的json字符串 */public static void ParseJsonStr(String str) {JSONObject obj = JSONObject.fromObject(str);System.out.println(obj);String name = obj.getString("name");String hobby = obj.getString("hobby");JSONObject message = obj.getJSONObject("message");String love = message.getString("love");String sex = message.getString("sex");int age = message.getInt("age");String englishName = message.getString("EnglishName");System.out.println(hobby);System.out.println(name + ">>" + hobby + ">>" + love + ">>" + sex+ ">>" + age + ">>" + englishName);}}

这样，一个java的Webservice完成了，并进行的现在比较流行的xml，json的解析，希望大家看了之后对自己有所帮助，如有疑问，留言讨论
