用CXF将你的Java程序发布成Web Service（1）

首先配置CXF环境，从apache下载cxf所需jar包。加入你的构建路径。

第二，建立一个DTO对象（用于参数是值对象类型），如下：

package bean;

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlRootElement;
import javax.xml.bind.annotation.XmlType;

/**

*@author  刘岩

*/

@XmlRootElement(name = "Customer")
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(propOrder = { "name", "age" })
public class Customer {

 private String name;
 private int age;

 public String getName() {
  return name;
 }

 public void setName(String name) {
  this.name = name;
 }

 public int getAge() {
  return age;
 }

 public void setAge(int age) {
  this.age = age;
 }

}
因为采用了注解形式，若不是JDK1.5，那你只能望CXF而兴叹了，还是用XFire吧。

接下来定义服务接口

package service;

import javax.jws.WebService;

import bean.Customer;

/**

*@author  刘岩

*/

@WebService(targetNamespace="iscpWebService/RemoveCooperater")
public interface CXFService {

 public String sayHello(String inStr);
 
 public void saveCust(Customer customer);

}
下面写接口实现类

package service.impl;

import javax.jws.WebService;

import bean.Customer;

import service.CXFService;

/**

*@author  刘岩

*/

@WebService(targetNamespace = "iscpWebService/RemoveCooperater", endpointInterface = "service.CXFService")
public class CXFServiceImpl implements CXFService {

 public String sayHello(String inStr) {

  System.out.println("服务端调用");

  inStr = "<hello~~~~：>" + inStr;
  return inStr;
 }

 public void saveCust(Customer customer) {

  if (customer != null) {
   customer.setName(customer.getName()+"@123");
   System.out.println(customer.getName() + ":" + customer.getAge());
  }

 }

}

因为CXF依赖于Spring框架，所以

web.xml修改如下：

<?xml version="1.0" encoding="UTF-8"?>
<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">
 
 <context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>WEB-INF/beans.xml</param-value>
 </context-param>

 <listener>
  <listener-class>
   org.springframework.web.context.ContextLoaderListener
  </listener-class>
 </listener>

 <servlet>
  <servlet-name>CXFServlet</servlet-name>
  <servlet-class>
   org.apache.cxf.transport.servlet.CXFServlet
  </servlet-class>
  <load-on-startup>1</load-on-startup>
 </servlet>

 <servlet-mapping>
  <servlet-name>CXFServlet</servlet-name>
  <url-pattern>/webservice/*</url-pattern>
 </servlet-mapping>

</web-app>

而Spring的bean.xml内容如下：

<?xml version="1.0" encoding="UTF-8"?>
<!-- START SNIPPET: beans -->
<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.xsd
http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">

 <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" />

 <jaxws:endpoint id="sayHello"
  implementor="service.impl.CXFServiceImpl" address="/CXFService"/>

</beans>

==================================================
好了，之后建立一个客户端项目(纯Java项目即可,无需Java Web支持),加入junit单元测试即可。

写客户端代码如下：

package test;

import junit.framework.TestCase;

import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;

public class Client extends TestCase {

 public void test01() {
  JaxWsProxyFactoryBean factoryBean = new JaxWsProxyFactoryBean();
  factoryBean.setServiceClass(CXFService.class);
  factoryBean
    .setAddress("http://127.0.0.1:8181/MyCXFDemo/webservice/CXFService");

  CXFService client = (CXFService) factoryBean.create();

  String response = client.sayHello("liuyan");
  System.out.println("Response: " + response);
  System.exit(0);
 }
 
 public void test02() {
  JaxWsProxyFactoryBean factoryBean = new JaxWsProxyFactoryBean();
  factoryBean.setServiceClass(CXFService.class);
  factoryBean
    .setAddress("http://127.0.0.1:8181/MyCXFDemo/webservice/CXFService");

  CXFService client = (CXFService) factoryBean.create();
  
  Customer customer = new Customer();
  customer.setAge(25);
  customer.setName("liuyan");
  
  client.saveCust(customer);
  
  System.out.println("Response: " + customer.getName());
  System.exit(0);
 }
}
运行test01、test02成功调用服务端代码。tomcat、weblogic都测试通过。注意：有些情况是在tomcat可以正常生成wsdl，但是移植到了weblogic下面会因为jar冲突导致wsdl不能生成。

wsdl如下，用它也可以生成客户端代码：：：
