易優商城 SSM配置文件（一）

本項目採用dubbo分佈式架構：現在主要配置服務提供者（service）

（1）使用mybaits 逆向工程生成pojo和相關mapper映射文件
（2）配置sqlMapConfig.xml文件: “暫時只需要引入頭文件”

<?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>

<!--此處可以引入mybatis的第三方插件-->
</configuration>

（3）配置spring的核心配置文件： 此處分爲三個配置文件，dao，service，transaction

spring-dao.xml文件：
1）配置據庫連接池:
加載jdbc.properties配置文件；
配置dataSource數據源；
2）配置sqlSessionFactory ：使用spring管理sqlSessionFactory和mybatis，
3）配置mapper映射文件

      </bean>

    </beans>

spring-service.xml 配置文件：用來暴露服務，同時提供服務接口；
1）配置包掃描器；用於掃描業務層
2）使用dubbo發佈服務

    <!-- 聲明需要暴露服務的端口 -->
    <dubbo:service interface="cn.yiyou.service.ItemService" ref="itemServiceImpl" timeout="600000" > </dubbo:service>

    </beans>

 </servlet-mapping>
  <!-- 解決pos亂碼 -->
 <filter>
    <filter-name>CharacterEncodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
       <param-name>encoding</param-name>
