WebService开发实例 (Xfire+Spring+Hibernate)
本文摘自：http://blog.csdn.net/caok/archive/2008/12/29/3637734.aspx
请注意，需要下载Xfire1.2.6、spring2.0,hibernate 3.0相关类库及相关数据库的jdbc驱动。本文相关内容是在myeclipse5.1下完成。
一、 首先在web.xml中添加对xfire及spring支持的相关内容，如下:
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
<!-- START SNIPPET: xfire -->
<context-param>
<!—xfire及spring相关配置文件位置 -->
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.xml
classpath:org/codehaus/xfire/spring/xfire.xml</param-value>
</context-param>
<context-param>

<param-value>/WEB-INF/log4j.properties</param-value>

</context-param>

</filter>
<filter-mapping>

<url-pattern>/services/*</url-pattern>
</filter-mapping>
<listener>

</servlet>
<servlet-mapping>
<servlet-name>xfire</servlet-name>
<url-pattern>/services/*</url-pattern>
</servlet-mapping>
<!-- END SNIPPET: xfire -->
</web-app>
二、 applicationContext.xml文件内容：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN" "http://www.springframework.org/dtd/spring-beans-2.0.dtd">
<beans>
<!-- 数据库连接配置 -->
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location" value="/WEB-INF/jdbc_connect.properties"/>
</bean>
<!-- C3P0连接池配置 -->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
<property name="driverClass" value="${jdbc.driverClassName}"/>
<property name="jdbcUrl" value="${jdbc.url}"/>
<property name="user" value="${jdbc.username}"/>
<property name="password" value="${jdbc.password}"/>
<property name="initialPoolSize">
<value>5</value>
</property>
<property name="minPoolSize">
<value>5</value>
</property>
<property name="maxPoolSize">
<value>10</value>
</property>
<property name="acquireIncrement">
<value>2</value>
</property>
<property name="maxIdleTime">
<value>60</value>
</property>
<property name="maxStatements">
<value>0</value>
</property>
</bean>
<!-- C3P0结束 -->
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="mappingResources">
<list>
<!—hibernate的hbm文件位置 ，至于hbm文件可以通过工具生成，这里就不详述了-->
<value>com/dao/emp.hbm.xml</value>
</list>
</property>
<property name="hibernateProperties">

<prop key="hibernate.dialect">${hibernate.dialect}</prop>
<prop key="hibernate.show_sql">true</prop>

<prop key="hibernate.use_outer_join">true</prop>
<prop key="hibernate.connection.SetBigStringTryClob">true</prop>
</props>
</property>
<property name="eventListeners">
<map>
<entry key="merge">
<bean class="org.springframework.orm.hibernate3.support.IdTransferringMergeEventListener"/>
</entry>
</map>
</property>
</bean>
<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>
<bean id="QueryHib" class="Hello.HelloworldImpl ">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>
<!—webservice 的bean类 -->
<bean id="QueryHibRis" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
<property name="transactionManager" ref="transactionManager"/>
<property name="target" ref="QueryHib"/>
<property name="transactionAttributes">
<props>
<prop key="*">PROPAGATION_REQUIRED</prop>
</props>
</property>
</bean>
</beans>
<!-- jdbc_connect.properties文件内容,主要是数据库配置,以下是oracle数据库 -->
jdbc.driverClassName=oracle.jdbc.driver.OracleDriver
jdbc.url=jdbc:oracle:thin:@172.17.99.230:1521:bsrun
jdbc.username=user
jdbc.password=user
hibernate.dialect=org.hibernate.dialect.Oracle9Dialect
四、Hello.HelloworldImpl类内容，主要是查询数据库并返回结果
package Hello;
import java.util.Collection;
//Generated by MyEclipse
public class HelloworldImpl implements IHelloworld {
public Collection User(){
return getHibernateTemplate().find("select new Helloworld.User(userid,username) from emp");
}
}
//IHelloworld接口内容
package Hello;
//Generated by MyEclipse
import java.util.Collection;
public interface IHelloworld {
public Collection User();
}
//xfire对于返回collection的，需要定义接口的IHelloworld.aegis.xml文件,需放在当前接口文件目录下。
<?xml version="1.0" encoding="UTF-8"?>
<mappings>
<mapping>
<method name= "User" >
<return-type componentType= "Helloworld.User" />
</method>
</mapping>
</mappings>
Helloworld.User类内容:
package Helloworld;
public class User {
String userid;
String username;
//一定要定义此构造函数,在Hello.HelloworldImpl中有用到哟。
Public User(String userid,String username){
this.userid = userid;
this.username = username;
}
public String getUserid() {
return userid;
}
public void setUserid(String userid) {
this.userid = userid;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
}
