spring 集成cxf 第二弹（经过测试）以xml格式进行数据交互

为方便打大家学习以及应用，还是从配置文件、jar、bean开始扯起。。。。。。

1,web.xml 配置文件基本配置

<web-app version="2.4"
	xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
	http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

	<display-name>Spring MVC Application</display-name>
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath*:spring-cxf.xml</param-value>
	</context-param>

    <servlet>
		<servlet-name>mvc-dispatcher</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>mvc-dispatcher</servlet-name>
		<url-pattern>*.do</url-pattern>
	</servlet-mapping>
	<!--spring 集成cxf web配置-->
	<servlet>
		<servlet-name>CXFServlet</servlet-name>
		<servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
	</servlet>
	<!-- CXFServlet Mapping -->
	<servlet-mapping>
		<servlet-name>CXFServlet</servlet-name>
		<url-pattern>/cxf/*</url-pattern>
	</servlet-mapping>

</web-app>

这里配置的cxf servlet的对应关系，我的拦截路径是/cxf/ 下的所有url。

2，pom.xml 配置文件，添加cxf开发需要的maven依赖

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

        </dependency>
        <!--CXF 依赖-->

                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

3，简单的spring配置文件，这里不多讲了。

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">
    <!--注解驱动-->
    <mvc:annotation-driven/>
    <context:component-scan base-package="com.spring"/>

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/pages/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
</beans>

4，针对cxf 实现的需要，增加spring-cxf.xml 配置文件，这里在web.xml 里已经做了引入

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:jaxws="http://cxf.apache.org/jaxws"
       xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
        http://cxf.apache.org/jaxws
        http://cxf.apache.org/schemas/jaxws.xsd">
    <!-- Import Apache CXF Bean Definition -->
    <import resource="classpath:META-INF/cxf/cxf.xml"/>
    <!--<import resource="classpath:META-INF/cxf/cxf-extension-soap.xml"/>-->
    <import resource="classpath:META-INF/cxf/cxf-servlet.xml"/>

    <!--模拟服务端① webservice-->
    <bean id="hello" class="com.spring.service.impl.HelloWordServiceImpl"/>
    <!--implementor="#hello" 指向bean id="hello"-->
    <jaxws:endpoint id="helloWorld" implementor="#hello" address="/helloWorld" />
    <!--模拟服务端②-->
    <bean id="user" class="com.spring.service.impl.UserServiceImpl"/>
    <jaxws:endpoint id="userPoint" implementor="#user" address="/user"/>
    <!--模拟客户端①-->
    <jaxws:client id="client"
                  serviceClass="com.spring.service.IHelloWord"
                  address="http://localhost:8080/cxf/helloWorld" />
    <!--模拟客户端②-->

</beans>

这里demo应用的是的这个配置，其他与当前的demo没有关系。

5，针对xml格式的数据实现的工具封装的实现。

package com.spring.utils;

import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;
import org.xml.sax.InputSource;

import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;
import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.FileOutputStream;
import java.io.StringReader;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

/**
 *生成xml格式的文件
 * 解释xml格式的字符串
 */
public class XMLHandler {
    /**
     * 创建xml
     * @return
     */
    public static String createXML(){
        String xmlStr="";
        //doc 的工厂
        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        try{
            DocumentBuilder builder = factory.newDocumentBuilder();
            Document document = builder.newDocument();
            document.setXmlVersion("1.0");
            //
            Element root = document.createElement("root");
            document.appendChild(root);
            //
            Element user = document.createElement("user");
            //
            Element id = document.createElement("id");
            id.setTextContent("1");
            user.appendChild(id);
            //
            Element name = document.createElement("name");
            name.setTextContent("张三");
            user.appendChild(name);
            //
            Element sex = document.createElement("sex");
            sex.setTextContent("男");
            user.appendChild(sex);
            //
            root.appendChild(user);
            //
            TransformerFactory transFactory = TransformerFactory.newInstance();
            Transformer transFormer = transFactory.newTransformer();
            DOMSource domSource = new DOMSource(document);

            //export string
            ByteArrayOutputStream bos = new ByteArrayOutputStream();
            transFormer.transform(domSource, new StreamResult(bos));
            xmlStr = bos.toString();
            System.out.println("输出结果"+xmlStr);
            //通过输出流输出
            File file = new File("D:/out/user.xml");
            if(!file.exists()){
                file.createNewFile();
            }
            FileOutputStream out = new FileOutputStream(file);
            StreamResult xmlResult = new StreamResult(out);
            transFormer.transform(domSource, xmlResult);
        }catch(Exception e){
            e.printStackTrace();
        }
        return xmlStr;
    }

    /*public static void main(String[] args) {
        createXML();
    }*/
    /**
     * 转化xml格式的字符串
     * <?xml version="1.0" encoding="UTF-8" standalone="no"?>
     *     <root>
     *         <user>
     *             <id>1</id>
     *             <name>张三</name>
     *             <sex>男</sex>
     *         </user>
     *     </root>
     */
    public static List<Map<String,Object>> parseXML(String xmlStr){
        List<Map<String,Object>> list=null;
        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        try{
            DocumentBuilder builder = factory.newDocumentBuilder();
            StringReader sr = new StringReader(xmlStr);
            InputSource is = new InputSource(sr);
            Document doc = builder.parse(is);
            //
            Element rootElement = doc.getDocumentElement();
            //
            NodeList users = rootElement.getElementsByTagName("user");
            //
            list=new ArrayList<Map<String, Object>>();
            for(int i=0;i<users.getLength();i++){
                Node node = users.item(i);
                NodeList childs = node.getChildNodes();
                Map<String,Object> map=new HashMap<String, Object>();
                for(int j=0;j<childs.getLength();j++){
                    Node childNode = childs.item(j);
                    String nodeName=childNode.getNodeName();
                    String value=childNode.getTextContent();
                    map.put(nodeName,value);

                }
                list.add(map);
            }

        }catch(Exception e){
            e.printStackTrace();
        }
        return list;
    }

    /*public static void main(String[] args) {
        String xmlStr="<?xml version='1.0' encoding='UTF-8' standalone='no'?><root><user><id>1</id><name>张三</name><sex>男</sex></user></root>";
        List<Map<String, Object>> list = parseXML(xmlStr);
        System.out.println("======"+list.toString());
    }*/
}

6，定义一个接口实现类，注意该class的注解。

package com.spring.service;

import javax.jws.WebParam;
import javax.jws.WebService;

/**
 * 
 */
@WebService
public interface IUser {
    //获取xml格式的数据
    /**
     * 根据传递的条件获取相册信息
     * xml的格式规范
     * <?xml version="1.0" encoding="UTF-8" standalone="no"?>
     *     <root>
     *         <user>
     *             <id>1</id>
     *             <name>张三</name>
     *             <sex>男</sex>
     *         </user>
     *     </root>
     * 这里的WebParam必须指定，否则调用的时候返回null
     * @return
     */
    String getUser(@WebParam(name = "xmlStr")String xmlStr);
}

7，实现该接口，注意注解的应用。

package com.spring.service.impl;

import com.spring.service.IUser;
import com.spring.utils.XMLHandler;

import javax.jws.WebService;
import java.util.List;
import java.util.Map;

/**
 * 
 */
@WebService
public class UserServiceImpl implements IUser {

    @Override
    public String getUser(String xmlStr) {
        List<Map<String, Object>> list = XMLHandler.parseXML(xmlStr);
        return list.toString();
    }
}

8，main方法测试。

package com.spring.test;


import org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory;

import javax.xml.namespace.QName;

/**
 *
 */
public class TestClientCxf {
    public static void main(String[] args) throws Exception {
        String xmlStr="<?xml version='1.0' encoding='UTF-8' standalone='no'?><root><user><id>1</id><name>张三</name><sex>男</sex></user></root>";
        JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
        org.apache.cxf.endpoint.Client client = dcf.createClient("http://localhost:8080/cxf/user?wsdl");
        //url为调用webService的wsdl地址
        QName name=new QName("http://service.spring.com/","getUser");
        //paramvalue为参数值
        Object[] objects=client.invoke(name,xmlStr);
        //调用web Service//输出调用结果
        System.out.println("输出结果："+objects[0].toString());
        /*User user = new User(xmlStr);
        Object obj = user.getUser();
        System.out.println("========="+obj.toString());*/
    }
}

这里注意：url 调用的webService的wsdl的地址为浏览器访问

http://localhost:8080/cxf/user?wsdl

路径产生的，cxf的服务端搭建是否成功，需要再浏览器访问一下你的配置路径，/user 定义在spring-cxf.xml 的配置文件

  <jaxws:endpoint id="userPoint" implementor="#user" address="/user"/>

效果图：

//url为调用webService的wsdl地址
        QName name=new QName("http://service.spring.com/","getUser");

图中标注的就是命名空间，getUser 指的是接口的中定义的方法名称。

到这里基本就算结束了，总结的不够精细，还望担待。
