cxf + spring 开发基于web服务的分布式异构数据同步更新应用技术研究

本课题主要解决不同平台和不同应用系统之间的数据转换、数据同步和多个数据源的共享集成问题。为解决该问题，采用基于Web服务的方式来进行数据的交互，主要要考虑如何保持两个系统中的数据能实时同步更新（增加、删除和修改）。

用cxf-2.6.1+spring 3.1.0+ hibernate3.6 版本开发web services

 

服务端的开发

interface IHelloService

package com.dx.service;

import javax.jws.WebMethod;
import javax.jws.WebService;

import com.dx.model.User;

@WebService
public interface IHelloService {

	@WebMethod
	public String sayHello(String username);
	
	@WebMethod
	public User getUser(int id);
	
	@WebMethod
	public void add(User user);
}

 

IHelloService 的实现 IHelloServiceImpl

package com.dx.service.impl;

import javax.jws.WebMethod;
import javax.jws.WebService;

import com.dx.dao.BaseDao;
import com.dx.model.User;
import com.dx.service.IHelloService;

@WebService
public class IHelloServiceImpl implements IHelloService{

	private BaseDao baseDao;
	
	
	@Override
	@WebMethod
	public String sayHello(String username) {
		return "Hello "+username;
	}

	@Override
	@WebMethod
	public User getUser(int id) {
		User user = new User();
		user.setName("杨钰莹");
		user.setId(id);
		
		return user;
	}

	@Override
	@WebMethod
	public void add(User user) {
		baseDao.save(user);
	}

	public BaseDao getBaseDao() {
		return baseDao;
	}

	public void setBaseDao(BaseDao baseDao) {
		this.baseDao = baseDao;
	}
	
}

 

spring applicationContext-user.xml的配置

<?xml version="1.0" encoding="UTF-8"?>
<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:jaxws="http://cxf.apache.org/jaxws"

	http://cxf.apache.org/jaxws  
	http://cxf.apache.org/schemas/jaxws.xsd">

	<jaxws:endpoint id="hellos"  address="/Hellows" implementor="#helloService">
	</jaxws:endpoint>
	
	<bean id="helloService" class="com.dx.service.impl.IHelloServiceImpl">
	  <property name="baseDao" ref="baseDao"></property>
	</bean>
	
	
	
	
</beans>

 web.xml的配置

好了，接下来部署启动tomcat ，在浏览器输入 http://localhost:8080/cxf_web_010/services

 

在出现的页面上 点击WSDL : {http://impl.service.dx.com/}IHelloServiceImplService

出现页面

  <?xml version="1.0" encoding="UTF-8" ?>

现在web services 已经发布了，下一章编写客户端
