易优商城 SSM配置文件（一）

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>

<!--此处可以引入mybatis的第三方插件-->
</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"?>

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"

<context:component-scan base-package="cn.yiyou.service"></context:component-scan>

<!-- 使用dubbo发布服务 -->
<!-- 提供方应用信息，用于计算依赖关系 -->
<dubbo:application name="yiyou-manager"/>
<!-- 设置注册中心 -->
<dubbo:registry protocol="zookeeper" address="192.168.1.4:2181"></dubbo:registry>
<!-- 用dubbo协议在20880端口暴露服务

<!-- 声明需要暴露服务的端口 -->
<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"

<!-- 配置事务管理 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<!-- 数据源 -->
<property name="dataSource" ref="dataSource"></property>
</bean>

<!-- 通知 -->
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<!-- 传播行为 -->
<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>

c5ed
</tx:advice>

<!-- 切面 -->
<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）

<!-- 加载spring容器 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<!-- 加载以applicationContext开头的xml文件 -->
<param-value>classpath:spring/applicationContext*.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</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

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

（2）配置web.xml

<!-- springMVC前端控制器 -->
<servlet>
