由web.xml可以看出來，在<context></context>中配置了上下文掃描

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath*:spring/*.xml</param-value>
    </context-param>

現在就對上下文進行配置，你在<param-value></param-value>配置的路徑就是你的上下文路徑，本次配置的意思就是在spring資料夾下的所有.xml檔案

1. spring-dao.xml配置：spring整合mybatis，配置資料來源，配置資料工廠，配置事物可以通用註解的形式啟用

1. spring-main.xml：spring整合
   1. spring通過註解的形式載入propertites檔案，
   2. 配置json轉換
   3. spring配置全域性掃描
