application-context.xml是全局的,应用于多个serverlet,配合listener一起使用,web.xml中配置如下:
<!-- 配置监听器 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
spring-mvc.xml 是spring mvc的配置,web.xml中配置如下:
<!--配置springmvc DispatcherServlet-->
<servlet>
<servlet-name>springMVC</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:config/spring-mvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
<async-supported>true</async-supported>
</servlet>
application-context.xml这个一般是采用非spring mvc架构,用来加载Application Context。
如果直接采用SpringMVC,只需要把所有相关配置放到spring-mvc.xml中就好,一般spring mvc项目用不到多个serverlet
