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" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd 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" ?> - <wsdl:definitions name="IHelloServiceImplService" targetNamespace="http://impl.service.dx.com/" xmlns:ns1="http://service.dx.com/" xmlns:ns2="http://schemas.xmlsoap.org/soap/http" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://impl.service.dx.com/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <wsdl:import location="http://localhost:8080/cxf_web_010/services/Hellows?wsdl=IHelloService.wsdl" namespace="http://service.dx.com/" /> - <wsdl:binding name="IHelloServiceImplServiceSoapBinding" type="ns1:IHelloService"> <soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http" /> - <wsdl:operation name="sayHello"> <soap:operation soapAction="" style="document" /> - <wsdl:input name="sayHello"> <soap:body use="literal" /> </wsdl:input> - <wsdl:output name="sayHelloResponse"> <soap:body use="literal" /> </wsdl:output> </wsdl:operation> - <wsdl:operation name="add"> <soap:operation soapAction="" style="document" /> - <wsdl:input name="add"> <soap:body use="literal" /> </wsdl:input> - <wsdl:output name="addResponse"> <soap:body use="literal" /> </wsdl:output> </wsdl:operation> - <wsdl:operation name="getUser"> <soap:operation soapAction="" style="document" /> - <wsdl:input name="getUser"> <soap:body use="literal" /> </wsdl:input> - <wsdl:output name="getUserResponse"> <soap:body use="literal" /> </wsdl:output> </wsdl:operation> </wsdl:binding> - <wsdl:service name="IHelloServiceImplService"> - <wsdl:port binding="tns:IHelloServiceImplServiceSoapBinding" name="IHelloServiceImplPort"> <soap:address location="http://localhost:8080/cxf_web_010/services/Hellows" /> </wsdl:port> </wsdl:service> </wsdl:definitions>
现在web services 已经发布了,下一章编写客户端
