完成前台门户页面系统功能（十）门户系统的建立以及服务层系统的建立
1.有关门户页面的效果展示：
2.有关门户系统的体系架构 ：
优点：
1、前台系统和服务层可以分开，降低系统的耦合度。
2、开发团队可以分开，提高开发效率
3、系统分开可以灵活的进行分布式部署。
缺点：服务之间通信使用接口通信，开发工作量提高。我们的前台系统分为两部分，一部分是服务层 web 工程，功能就是发布服务另外一部分：表现层，展示页面，没有业务逻辑。所有业务逻辑就是调用服务层的服务。
3.构造服务层系统jingxi-rest（也是一个maven项目）打包方式：war
3.1 SqlMapConfig.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration PUBLIC " -//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<!--配置分页插件-->
<plugins>
<plugin interceptor="com.github.pagehelper.PageHelper">
<!--设置数据库类型Oracle,Mysql,MariaDB,SQLite,Hsqldb,PostgreSQL六种数据库-->
<property name="dialect" value="mysql"/>
</plugin>
</plugins>
</configuration>
3.2 db.properties文件
jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/jingxi?characterEncoding=utf-8 jdbc.username=root jdbc.password=123456
3.3 applicationContext-mybatis.xml文件
（1.配置数据库连接池 2.使用mybatis管理sqlsessionfactory 3.加载mybatis的全局配置文件 4.扫描数据库映射的mapper）

3.4 applicationContext-mvc.xml文件
（配置包的扫描器，扫描@controller注解的类）
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <context:component-scan base-package="com.jingxi.rest.controller"/> <mvc:annotation-driven /> </beans>
3.5 applicationContext-service.xml文件
（配置事物，配置切面）
