Listing 5-31. Configuring ContextLoaderListener in web.xml
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
By default,
ContextLoaderListener
loads the application context file stored in your
WEB-INF
directory.
This location can be overridden by defining the
contextConfigLocation
context parameter in
web.xml
, as shown in Listing 5-32.
Listing 5-32. File Locations Using the contextConfigLocation Parameter
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
classpath:service-context.xml
classpath:data-access-context.xml
</param-value>
</context-param>
At this point, the configuration of
WebApplicationContext
in
web.xml
looks like Listing 5-33.
Listing 5-33. Web.xml with ContextLoaderListener and contextConfigLocation
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
classpath:service-context.xml
classpath:data-access-context.xml
</param-value>
</context-param>
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
Note
ContextLoaderListener
by default looks for a
/WEB-INF/applicationContext.xml
file if
you do not specify a
<context-param>
named
contextConfigLocation
.
Now that you know how to configure
WebApplicationContext
in a web application, we can move on
to the second object,
DispatcherServlet
, that is configured in the
web.xml
file.
