本项目采用dubbo分布式架构：现在主要配置服务提供者（service）

（1）使用mybaits 逆向工程生成pojo和相关mapper映射文件  
（2）配置sqlMapConfig.xml文件: “暂时只需要引入头文件”

<?xml version="1.0" encoding="UTF-8" ?>
    <!DOCTYPE configuration PUBLIC "-//www.mybatis.org//DTD Config 3.0//EN" "http://www.mybatis.org/dtd/mybatis-3-config.dtd">
    <configuration>
    
    
    </configuration>

（3）配置spring的核心配置文件： 此处分为三个配置文件，dao，service，transaction

spring-dao.xml文件：  
1）配置据库连接池:  
加载jdbc.properties配置文件；  
配置dataSource数据源；  
2）配置sqlSessionFactory ：使用spring管理sqlSessionFactory和mybatis，  
3）配置mapper映射文件

<?xml version="1.0" encoding="UTF-8"?>

       <context:property-placeholder location="classpath:config/*.properties" />
       
       
           <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" destroy-method="close">
         
         <property name="url" value="${jdbc.url}"></property>
         
         <property name="driverClassName" value="${jdbc.driver}"></property>
         
         <property name="username" value="${jdbc.username}"></property>
         
         <property name="password" value="${jdbc.password}"></property>
         
         <property name="maxActive" value="10"></property>
         
         <property name="minIdle" value="5"></property>
       </bean>
          
       <bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean">
          
          <property name="dataSource" ref="dataSource"></property>
          
          <property name="configLocation" value="classpath:mybatis/SqlMapConfig.xml"></property>

             <property name="basePackage" value="cn.yiyou.mapper"></property>
          </bean>
    
        </beans>

spring-service.xml 配置文件：用来暴露服务，同时提供服务接口；  
1）配置包扫描器；用于扫描业务层  
2）使用dubbo发布服务

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:dubbo="http://code.alibabatech.com/schema/dubbo" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.2.xsd http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.2.xsd">
        
        <context:component-scan base-package="cn.yiyou.service"></context:component-scan>
    
        
        
        <dubbo:application name="yiyou-manager"/>
        
        <dubbo:registry protocol="zookeeper" address="192.168.1.4:2181"></dubbo:registry>
        
        <dubbo:protocol name="dubbo" port="20880"></dubbo:protocol>
        
        <dubbo:service interface="cn.yiyou.service.ItemService" ref="itemServiceImpl" timeout="600000" > </dubbo:service>
    
        </beans>

spring-transaction.xml ：事务  
1）配置事务管理；DataSourceTransactionManager  
2）配置事务通知：tx:advice  
3）配置切面：aop

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.2.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.2.xsd">
    
     
         <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
           
           <property name="dataSource" ref="dataSource"></property>
         </bean>
    
         
         <tx:advice id="txAdvice" transaction-manager="transactionManager">
               <tx:attributes>
                
                <tx:method name="save*" propagation="REQUIRED" />
                <tx:method name="insert*" propagation="REQUIRED" />
                <tx:method name="add*" propagation="REQUIRED" />
                <tx:method name="create*" propagation="REQUIRED" />

                <tx:method name="select*" propagation="SUPPORTS" read-only="true" />
                <tx:method name="get*" propagation="SUPPORTS" read-only="true" />
               </tx:attributes>
         </tx:advice>
    
         
         <aop:config>
            <aop:advisor advice-ref="txAdvice" pointcut="execution(* cn.yiyou.service..*.*(..)`` " />
         </aop:config>
        </beans>

（4）配置web.xml 文件：（初始化spring容器）

     </listener>

配置服务引用方（web）：  
（1）springmvc-servlet.xml:表现层的配置  
1）注解驱动  
2）配置controller包扫描器  
3）配置视图解析器：internelResourceViewResolver  
4）配置静态资源映射  
5）引用dubbo服务
