## @ImportResource()注解(注入spring配置文件) ##

*  @ImportResource注解用于导入Spring的配置文件，让配置文件里面的内容生效；(就是以前写的[springmvc][].xml、applicationContext.xml)
 *  Spring Boot里面没有Spring的配置文件，我们自己编写的配置文件，也不能自动识别；
 *  想让Spring的配置文件生效，加载进来；@ImportResource标注在一个配置类上。
 *  **注意！这个注解是放在主入口函数的类上，而不是测试类上**
 *  不使用@ImportResource()注解，程序根本不能对我们spring的配置文件进行加载，所以我们需要将spring配置文件加载到容器里。
