【SSM】【3】spring容器配置

由web.xml可以看出来，在<context></context>中配置了上下文扫描

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

现在就对上下文进行配置，你在<param-value></param-value>配置的路径就是你的上下文路径，本次配置的意思就是在spring文件夹下的所有.xml文件

1. spring-dao.xml配置：spring整合mybatis，配置数据源，配置数据工厂，配置事物可以通用注解的形式启用

1. spring-main.xml：spring整合
   1. spring通过注解的形式加载propertites文件，
   2. 配置json转换
   3. spring配置全局扫描
