一、 准备工作
1、下载安装Eclipse Version: 3.3.1.1 和MyEclipse6.0.1
2、下载安装MySQL Server 5.1
3、下载MySQL驱动 mysql-connector-java-5.0.8-bin.jar
4、 使用MySQL管理工具创建数据库easyLife和一张user表。我使用的是EMS SQL Manager 2007 for MySQL。
表结构如下:
id |
integer |
username |
Varchar(20) |
userpwd |
Varchar(20) |
插入一条数据待测试用。
二、实例代码
连接数据库
打开MyEclipse Database Explorer 新建一个数据连接:
创建项目
1、打开MyEclipse 新建一个Web Service Project项目输入项目名称XfireWebService。
2、下一步默认
3、下一步,勾选XFire 1.2 HTTP Client Libraries。
4、点击View and edit libraries 去掉spring-1.2.6.jar 这个包(不去掉会和后面添加的Spring冲突)
5、右键添加MyEclipse的Spring Capabilities,方便起见选上所有的包,选择Copy checked…,下一步默认完成。
6、再添加Hibernate Capabilities,同样选上所有包。
下一步去掉复选框完成。
点击Replace替换所有包
7、然后配置web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.4"
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/classes/applicationContext.xml
classpath:org/codehaus/xfire/spring/xfire.xml
</param-value>
</context-param>
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
<servlet>
<servlet-name>xfire</servlet-name>
<servlet-class>
org.springframework.web.servlet.DispatcherServlet
</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>xfire</servlet-name>
<url-pattern>/services/*</url-pattern>
</servlet-mapping>
</web-app>
8、建立一个com.easylife包,再新建一个webservice
9、修改ILoginDAO
package com.easylife;
//Generated by MyEclipse
public interface ILoginDAO {
public boolean login(String username, String userpwd);
}
修改LoginDAOImpl
package com.easylife;
import java.util.List;
import org.hibernate.Query;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
//Generated by MyEclipse
public class LoginDAOImpl extends HibernateDaoSupport implements ILoginDAO {
@SuppressWarnings("unchecked")
public boolean login(String username, String userpwd) {
boolean flag = false;
String hql = "FROM User AS u WHERE u.username=? AND u.userpwd=?";
Query q = super.getSession().createQuery(hql);
q.setString(0, username);
q.setString(1, userpwd);
List all = q.list();
if (all.size() > 0) {
flag = true;
//SysUsers t = (SysUsers) all.get(0);
}
return flag;
}
}
10、打开MyEclipse Data Explorer视图找到user表使用Hibernate Reverse Engineering
11、在applicationContext.xml 末尾添加一个bean
<bean id="LoginDAOImpl" class="com.easylife.LoginDAOImpl">
<property name="sessionFactory">
<ref bean="sessionFactory" />
</property>
</bean>
12、在WEB-INF下建立xfire-servlet.xml
[img]<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "
http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<bean
class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="urlMap">
<map>
<entry key="/Login"><!--此为服务名-->
<ref bean="login" />
</entry>
</map>
</property>
</bean>
<bean id="login"
class="org.codehaus.xfire.spring.remoting.XFireExporter">
<property name="serviceFactory">
<ref bean="xfire.serviceFactory" />
</property>
<property name="xfire">
<ref bean="xfire" />
</property>
<property name="serviceBean">
<ref bean="LoginDAOImpl" /><!--在 applicationContext.xml 中装配的类-->
</property>
<property name="serviceClass">
<value>com.easylife.ILoginDAO</value><!--接口-->
</property>
</bean>
</beans>[/img]
13、部署项目
14、测试服务
http://localhost:8080/XfireWebService/services/Login?wsdl
15、java调用WebService
package com.easylife;
import java.net.MalformedURLException;
import java.util.Iterator;
import java.util.List;
import org.codehaus.xfire.XFireFactory;
import org.codehaus.xfire.client.XFireProxyFactory;
import org.codehaus.xfire.service.Service;
import org.codehaus.xfire.service.binding.ObjectServiceFactory;
import com.easylife.User;
import com.easylife.ILoginDAO;
public class UserServiceWSTest {
public static void main(String[] args) throws Exception {
// 创建服务实例
Service srvcModel = new ObjectServiceFactory()
.create(ILoginDAO.class);
XFireProxyFactory factory = // 创建代理工厂实例
new XFireProxyFactory(XFireFactory.newInstance().getXFire());
String helloWorldURL = "http://localhost:8080/XfireWebService/services/Login";
ILoginDAO srvc = null;
try { // 获取指定位置的web服务对象
srvc = (ILoginDAO) factory.create(srvcModel, helloWorldURL);
} catch (MalformedURLException e) {
e.printStackTrace();
}
// 调用只返回String的方法.在接口名.aegis.xml中不用设置方法名
boolean result = srvc.login("admin","123");
System.out.println(result);
Run As Java Application返回True
完毕
