服務端的配置檔案：    provider.xml

1. <?xmlversion="1.0"encoding="UTF-8"?>
2. <beansxmlns="http://www.springframework.org/schema/beans"
3.  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
4.  xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
5.  xsi:schemaLocation="http://www.springframework.org/schema/beans          
6.  http://www.springframework.org/schema/beans/spring-beans.xsd          
7.  http://code.alibabatech.com/schema/dubbo           
8.  http://code.alibabatech.com/schema/dubbo/dubbo.xsd         ">
9. <!-- Application name -->
10. <dubbo:applicationname="Frame"/>
11. <!-- registry address, used for service to register itself -->
12. <dubbo:registryaddress="multicast://224.5.6.7:1234"
    />
13. <!-- expose this service through dubbo protocol, through port 20880 -->
14. <dubbo:protocolname="dubbo"port="20880"/>
15. <!-- which service interface do we expose? -->
16. <dubbo:serviceinterface="merchant.shop.service.IHelloService"ref="helloService"/>
17.     <!-- bean配置 -->
18.     <
    beanid="helloService"
19.         class="merchant.shop.service.impl.HelloServiceImpl">
20.     </bean>
21. </beans>

此處interface的地址要與consumer端的一致，所以在服務端工程中新建了和客戶端工程一樣的路徑來儲存service

spring 配置檔案 ： providerApplicationContext.xml

1. <?xmlversion="1.0"encoding="UTF-8"?>
2. <beansxmlns="http://www.springframework.org/schema/beans"
3.     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
4.     xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">
5.     <!-- spring 與 ibatis 銜接 -->
6.     <beanid="sqlMapClient"class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
7.         <propertyname="configLocation"value="provider-sql-map-config.xml"></property>
8.         <propertyname="dataSource"ref="dataSource"/>
9.     </bean>
10.     <!-- 資料來源基本配置 -->
11.     <beanid="dataSource"
12.         class="org.springframework.jndi.JndiObjectFactoryBean">
13.         <propertyname="jndiName">
14.             <value>java:/comp/env/test</value>
15.         </property>
16.     </bean>
17.     <!-- 事務配置 -->
18.      <beanid="transactionManager"class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
19.     <propertyname="dataSource"ref="dataSource"></property>
20.     </bean>
21. <!-- 宣告式事務管理 -->
22.     <beanid="baseTransactionProxy"class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean"abstract="true">
23.         <propertyname="transactionManager"ref="transactionManager"></property>
24.         <propertyname="transactionAttributes">
25.             <props>
26.                 <propkey="add*">PROPAGATION_REQUIRED</prop>
27.                 <propkey="edit*">PROPAGATION_REQUIRED</prop>
28.                 <propkey="*">PROPAGATION_REQUIRED,readOnly</prop>
29.             </props>
30.         </property>
31.     </bean>
32. </beans>

服務端需要啟動的兩個檔案如下 ：

1. package com.sitech.comm.dubbo;  
2. import org.springframework.context.ApplicationContext;  
3. import org.springframework.context.support.ClassPathXmlApplicationContext;    
4. publicclass Provider {         
5.     publicstaticvoid init() throws Exception {           
6.         ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(new String[] {"provider.xml"});           
7.         context.start();    
8.         singleton();  
9.     }  
10.     publicstatic ApplicationContext context = null;  
11.      publicstatic ApplicationContext singleton() {  
12.             if (context == null) {  
13.                 context = new ClassPathXmlApplicationContext(new String[] {"providerApplicationContext.xml"});           
14.             }  
15.              return context;  
16.      };  
17. }   

1. package com.sitech.comm.dubbo;  
2. import javax.servlet.ServletException;  
3. import javax.servlet.http.HttpServlet;  
4. import com.sitech.comm.log.LogWritter;  
5. publicclass ProviderInit extends HttpServlet {  
6.     publicvoid init() throws ServletException {  
7.         try {  
8.             System.out.println("初始化dubbo服務端");  
9.             Provider.init();  
10.         } catch (Exception e) {  
11.             System.out.println("初始化dubbo服務端失敗");  
12.         }  
13.     }  
14. }  

web.xml 中增加啟動如下 ：

1. <servlet>
2.         <servlet-name>ProviderInit</servlet-name>
3.         <servlet-class>
4.             com.sitech.comm.dubbo.ProviderInit  
5.         </servlet-class>
6.         <load-on-startup>1</load-on-startup>
7.     </servlet>

consumer客戶端就可以遠端呼叫另一個工程的服務了

這裡出問題，一般都是配置檔案的問題，如資料庫的連線，spring 與 ibatis 銜接 時的配置檔案等
