Spring MVC ResourceBundleViewResolver example

In Spring MVC,

ResourceBundleViewResolver

is used to resolve “view named” based on view beans in “

.properties

” file.

By default,

ResourceBundleViewResolver

will loads the view beans from file

views.properties

, which located at the root of the project class path. However, this location can be overridden through the “

basename

” property, for example,

<beans ...>
<bean class="org.springframework.web.servlet.view.ResourceBundleViewResolver">
<property name="basename" value="spring-views" />
</bean>
</beans>

In above case, it loads the view beans from “

spring-views.properties

“, which located at the root of the project class path.

Note

The

ResourceBundleViewResolver

has the ability to load view beans from different resource bundles for different locales, but this use case is rarely required.

ResourceBundleViewResolver

example to show you how it works :

1. Controller

A controller class, return a view, named “

WelcomePage

“.

//...
public class WelcomeController extends AbstractController{

@Override
protected ModelAndView handleRequestInternal(HttpServletRequest request,
HttpServletResponse response) throws Exception {

ModelAndView model = new ModelAndView("WelcomePage");

return model;
}
}

2.

ResourceBundleViewResolver

Register

ResourceBundleViewResolver

in the Spring’s bean configuration file, change the default view beans location to “

spring-views.properties

“.

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd"> 
<bean
class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping" />

<!-- Register the bean -->
<bean class="com.mkyong.common.controller.WelcomeController" />

<bean class="org.springframework.web.servlet.view.ResourceBundleViewResolver">
<property name="basename" value="spring-views" />
</bean>

</beans>

3. View beans

Declare each view bean as a normal resource bundle style (key & message), where

“WelcomePage” is the view name to match.

“.(class)” is the type of view.

“.url” is the view’s URL location.

File :

spring-views.properties

WelcomePage.(class)=org.springframework.web.servlet.view.JstlView
WelcomePage.url=/WEB-INF/pages/WelcomePage.jsp

Note

Put this “

spring-views.properties

” file on your project class path.

How it works ?

When view name “

WelcomPage

” is returned by controller, the

ResourceBundleViewResolver

will find the key start with “

WelcomPage

” in “

spring-views.properties

” file, and return the corresponds view’s URL “

/WEB-INF/pages/WelcomPage.jsp

” back to the

DispatcherServlet

.
