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）
