java - How do the different contexts in Spring MVC work? -

i have following configuration spring mvc webapp. know conceptually difference between contextconfiglocation in servlet-context.xml (its conf appservlet) , others files security, tiles... don't understand how works because if put tiles-context.xml configuration in servlet-context app works , in other case no, security working properly. beans in files aren't in appservlet container also? there more 1 context?

<!-- dispatcherservlet conf - processes application requests --> <servlet>     <servlet-name>appservlet</servlet-name>     <servlet-class>org.springframework.web.servlet.dispatcherservlet</servlet-class>     <init-param>         <param-name>contextconfiglocation</param-name>         <param-value>classpath:servlet-context.xml</param-value>     </init-param>     <load-on-startup>1</load-on-startup> </servlet>  <servlet-mapping>     <servlet-name>appservlet</servlet-name>     <url-pattern>/</url-pattern> </servlet-mapping>   <!-- spring configuration files in xml --> <context-param>     <param-name>contextconfiglocation</param-name>     <param-value>         classpath:security-context.xml         classpath:tiles-context.xml         ...     </param-value> </context-param> 

take on

spring root application context , servlet context confusion

what difference between applicationcontext , webapplicationcontext in spring mvc?

for difference root context , servlet context.

you can define multiple servlet context configuration follows

<servlet> <servlet-name>api-dispatcher</servlet-name> <servlet-class>     org.springframework.web.servlet.dispatcherservlet </servlet-class> <init-param>   <param-name>contextconfiglocation</param-name>   <param-value>/web-inf/api-dispatcher-servlet.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>api-dispatcher</servlet-name> <url-pattern>/rest/*</url-pattern> 

above context accessible when url pattern /rest/*. how multiple separate context configured on spring.
