CXF框架的web service学习，传递xml并解析

一：所依赖的jar包：apache-cxf-2.7.10，可以再官网下载

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;

@WebService
public interface Hello {

  public String sayHello(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

package com;

import java.util.HashMap;
import java.util.Map;
@WebService(endpointInterface = "com.Hello")
public class HelloImpl implements Hello {

  @Override
  public String sayHello(String str) {
    System.out.println("web services调用成功");
    String result = createXml(str);
    return result;
  }

  /**
   * 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>呵呵</cinamaName>");
    sb.append("<director>" + name + "</director>");
    sb.append("<introduce>我是说明</introduce>");
    sb.append("<price>25</price>");
    sb.append("</Result>");
    return sb.toString();
  }

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

public static void main(String[] args) {
        try {
            DynamicClientFactory dcf = DynamicClientFactory.newInstance();
            Client client = dcf.createClient("http://localhost:18080/aiplat/service/helloService?wsdl");
            Object[] objs = client.invoke("sayHello","测试");　　　　　　　//接收结果　            System.out.println(objs[0]);         } catch (Exception e) {           e.printStackTrace();         } }

Spring 配置

    <jaxws:server id="helloService" serviceClass="com.Hello" address="/helloService">
        <jaxws:serviceBean>
             <ref bean="helloImpl"/>
         </jaxws:serviceBean>
    </jaxws:server>

XML的解析

/**
   * 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SAXBuilder
      DocumentBuilderFactory 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( node.getTextContent());
            } else if ("introduce".equals(node.getNodeName())) {
              System.out.println( node.getTextContent());
            } else if ("price".equals(node.getNodeName())) {
              System.out.println( node.getTextContent());
            } else if ("director".equals(node.getNodeName())) {
              System.out.println(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());
    }
  }
