 要搭建項目，先要將項目拆分成N層，將服務(service)層獨自放在A臺服務器專門提供服務，zookeepek也可以單獨放在一臺服務器B，A服務器運行的服務要註冊到B的zk註冊中心，將界面層和邏輯處理放在同一層，該層只運行(springMvc+spring)，該層也單獨放在C臺服務器。請求到C服務器，請求去B註冊中心找服務。找到對應服務，返回結果到界面。

一個完整的項目可以簡單拆分成：實體Po、servicedao、服務(service)、web呈現界面。簡單點理解就是提供者和消費者的關係。提供者：服務(service)，消費者：web呈現界面。

1、  建立實體Po Maven項目層。

該項目pom.xml不引用其他jar包，默認配置。

2、  建立servicedaoMaven項目層。

該項目要引用實體Po項目中的實體po，還要引用其他jar包，所以都在該項目的pom.xml中配置jar包的引用。

該項目的pom.xml文件配置

3、  建立提供者(service)MavenWeb項目

該項目要引用實體Po和servicedao和其他jar包，最主要的是各種配置文件要配置正確。

先是pom.xml的配置：

接着applicationContext.xml配置：

[html]  view plain  copy
  1. <?xml version="1.0" encoding="UTF-8"?>  
  2. <beans  
  3.     xmlns="http://www.springframework.org/schema/beans"

  24.     </context:component-scan>  
  25. </beans>  
再接着spring-mybatis.xml和 jdbc.properties 配置：

jdbc.properties：

[html]  view plain  copy
  1. driverClassName=com.mysql.jdbc.Driver  
  2. url=jdbc:mysql://192.168.3.16:3306/hotelmanagementsystem?useUnicode=true&characterEncoding=utf-8  
  3. username=root  
  4. password=123  
  5. validationQuery=SELECT 1

  124.     </aop:config>  
  125.       
  126.     </beans>  

再有spring-dubbo-provider.xml配置：

[html]  view plain  copy
  1. <?xml version="1.0" encoding="UTF-8"?>  
  2. <beans xmlns="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. <dubbo:application name="dubbo-service" />  
  10. <!-- zookeeper所在服務器IP地址，本地的就是127.0.0.1 -->  
  11.     <dubbo:registry address="zookeeper://127.168.3.16:2181" />  
  12.     <dubbo:protocol name="dubbo" port="20880" />  
  13.          <!-- 可以有多個Service -->  
  14.     <dubbo:service interface="end.gx.service.UserService" ref="userService" />  
  15.         <!-- 可以有多個ServiceImpl -->  
  16.     <bean id="userService" class="end.gx.service.impl.UserServiceImpl" />  
  17. </beans>  

最後web.xml配置：

[html]  view plain  copy
  1. <?xml version="1.0" encoding="UTF-8"?>  
  2. <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
  3.     xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"  
  4.     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"  
  5.     id="WebApp_ID" version="2.5">  
  6.

  11.         <param-value>  
  12.             classpath:applicationContext.xml,  
  13.             classpath:spring-mybatis.xml,  
  14.             classpath:spring-dubbo-provider.xml  
  15.         </param-value>  
  16.     </context-param>  
  17.   
  18.     <listener>  
  19.         <description>spring監聽器</description>  
  20.         <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  
  21.     </listener>  
  22. </web-app>  

4、建立消費方(web) MavenWeb項目

該項目要引用實體Po和servicedao,還要引用其他jar包。還有各種配置文件要正確配置。

先是pom.xml配置：

[html]  view plain  copy
  1. <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
  2.     xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
