分布式架构表现层web中读取Spring配置文件的2种方式

1.表现层的web.xml文件中优先加载Spring配置文件

 <!-- 加载spring容器 -->
  <context-param>
  	<param-name>contextConfigLocation</param-name>
  	<param-value>classpath:spring/*.xml</param-value>
  </context-param>
  <listener>
  	<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>

注意别忘了配置监听器listener,否则无法读取spring的配置文件,启动项目的时候的时候Autowired自动装配失败

2.springmvc.xml配置文件中进行首先进行spring依赖注入,再去扫描控制层Controller
