View resolver

A view resolver resolves a View name to the actual JSP page.

The View name in this example is welcome, and we would want it to resolve to /WEB-INF/views/welcome.jsp.

A view resolver can be configured in the spring context /WEB-INF/user-web-context.xml. Here's the code snippet for that:

    <bean class="org.springframework.web.
    servlet.view.InternalResourceViewResolver"> 
     <property name="prefix"> 
       <value>/WEB-INF/views/</value> 
     </property> 
     <property name="suffix"> 
       <value>.jsp</value> 
     </property> 
    </bean>

A few important points to note:

• org.springframework.web.servlet.view.InternalResourceViewResolver: A view resolver supporting JSPs. JstlView is typically used. It also supports tiles with a TilesView.
• <property name="prefix"> <value>/WEB-INF/views/</value> </property><property name="suffix"> <value>.jsp</value> </property>: This maps the prefix and suffix to be used by view resolver. View resolver takes the string from the controller method and resolves to the view: prefix + viewname + suffix. So, the view name welcome is resolved to /WEB-INF/views/welcome.jsp.
