Spring MVC RedirectView example

In Spring MVC, org.springframework.web.servlet.view.RedirectView, as name indicated, a view redirect to another absolute, context relative, or current request relative URL. In this tutorial, we show you a complete example to use RedirectView class.

1. RedirectView

Declare a RedirectView bean, named “DummyRedirect“, redirect to URL “DummyRedirectPage.htm“.

File : spring-views.xml

<beans ...>   <!-- Redirect view -->    <bean id="DummyRedirect"        class="org.springframework.web.servlet.view.RedirectView">           <property name="url" value="DummyRedirectPage.htm" />    </bean></beans>

2. Controller

A controller to return a ModelAndView named “DummyRedirect“, which is a RedirectView view.

File : DummyController.java

package com.mkyong.common.controller;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.springframework.web.servlet.ModelAndView;import org.springframework.web.servlet.mvc.AbstractController;public class DummyController extends AbstractController{    @Override    protected ModelAndView handleRequestInternal(HttpServletRequest request,        HttpServletResponse response) throws Exception {        return new ModelAndView("DummyRedirect");    }       }

3. Spring configuration

Declared all mappings.

File : mvc-dispatcher-servlet.xml

<beans ...>  <bean   class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping" />   <bean class="com.mkyong.common.controller.DummyController" />   <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">       <property name="mappings">            <props>                <prop key="/DummyRedirectPage.htm">dummyRedirectController</prop>            </props>        </property>    </bean>    <bean id="dummyRedirectController"          class="org.springframework.web.servlet.mvc.ParameterizableViewController">     <property name="viewName" value="DummyPage" />    </bean>    <bean id="viewResolver"          class="org.springframework.web.servlet.view.InternalResourceViewResolver" >          <property name="prefix">                <value>/WEB-INF/pages/</value>           </property>          <property name="suffix">                <value>.jsp</value>          </property>          <property name="order" value="1" />     </bean>     <bean class="org.springframework.web.servlet.view.XmlViewResolver">       <property name="location">           <value>/WEB-INF/spring-views.xml</value>       </property>       <property name="order" value="0" />     </bean></beans>

4. How it works?

1. Access the URL http://localhost:8080/SpringMVC/dummy.htm.

2. “ControllerClassNameHandlerMapping” matched “DummyController” and return a ModelAndView(“DummyRedirect”).

3. “XmlViewResolver” matched it and return an URL “DummyRedirectPage.htm“.

    <bean id="DummyRedirect"        class="org.springframework.web.servlet.view.RedirectView">       <property name="url" value="DummyRedirectPage.htm" />    </bean>

1. “SimpleUrlHandlerMapping” matched it and return a controller “dummyRedirectController“.

    <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">        <property name="mappings">            <props>                <prop key="/DummyRedirectPage.htm">dummyRedirectController</prop>            </props>        </property>    </bean>

1. The ParameterizableViewController controller, “dummyRedirectController“, return a view named “DummyPage“.

    <bean id="dummyRedirectController"         class="org.springframework.web.servlet.mvc.ParameterizableViewController">    <property name="viewName" value="DummyPage" />    </bean>

1. InternalResourceViewResolver matche it and return the final jsp page, “/WEB-INF/pages/DummyPage.jsp“.

    <bean id="viewResolver"       class="org.springframework.web.servlet.view.InternalResourceViewResolver" >          <property name="prefix">              <value>/WEB-INF/pages/</value>           </property>          <property name="suffix">             <value>.jsp</value>          </property>          <property name="order" value="1" />    </bean>

1. URL changed to “http://localhost:8080/SpringMVC/DummyRedirectPage.htm“.
   Redirect Prefix
   Alternative, if you have InternalResourceViewResolver configured, you can use the “Redirect Prefix” in the view name to resolve the redirect view. For example,

File : DummyController.java

//...public class DummyController extends AbstractController{    @Override    protected ModelAndView handleRequestInternal(HttpServletRequest request,        HttpServletResponse response) throws Exception {        return new ModelAndView("redirect:DummyRedirectPage.htm");    }       }

Use case
One of the use case is applying the “RedirectView” concept to solve the duplicated form submission in Spring MVC.
