Spring Web框架搭建配置
配置web.xml文件：
在tomcat启动时加载web.xml文件。
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

配置spring-common.xml文件：
配置了properties资源文件的加载路径以及自动注入的扫描路径。
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

配置datasource.properties文件：
主要用于配置数据库的连接信息，如驱动、方言、url、用户名、密码、心跳检测语句等。
jdbc_username=gis
jdbc_password=gis
jdbc_url=jdbc:oracle:thin:@localhost:1521:giser
jdbc_driver=oracle.jdbc.driver.OracleDriver
jdbc_dialect=org.hibernate.dialect.Oracle9Dialect
validationQuery=select 1 from dual
配置spring-mybatis.xml文件：
配置了数据源、事务，接口扫描路径等。
