Spring redirect using mvc:redirect-view-controller tag


This is an extension of my previous post on 
So if you have directly landed here I would highly recommend to read it first for setup.  In this post we will essentially see how can we redirect one URL to other using mvc:redirect-view-controller tag configuration.

Spring redirect using mvc:redirect-view-controller tag

Basic setup remains the same as that of previous post

NOTE : For this Spring 4.1+ is required! So change your ivy dependency accordingly.

        <dependency org="org.springframework" name="spring-webmvc"
            <exclude org="javax.servlet" name="javax.servlet-api" />
            <exclude org="javax.servlet.jsp" name="jsp-api" />
            <exclude org="javax.el" name="javax.el-api" />

Now only change that you need to do in your spring configuration is as follows - 

    <mvc:redirect-view-controller redirect-url="/TestWebProject/newtest" path="/oldtest" status-code="308" keep-query-params="true"/>
    <mvc:view-controller path="/newtest" view-name="test"/>

All it says is if you get a URL "/oldtest" redirect it to new URL "/newtest" and the 2nd line states if you get url "/newtest" then render view with logical name test which will again render the same JSP test.jsp as per the InternalResourceViewResolver.

Notice the redirect with 308 response status.

Alternate way to redirect is using

<mvc:view-controller path="/oldtest" view-name="redirect:newtest"/>
 <mvc:view-controller path="/newtest" view-name="test"/>

Again notices the 302 response code.

NOTE : It is not desirable to use version in xsd declaration. Spring will use highest version in the project's dependencies if version not given.

How to install Maven on Windows


  • We are going to install  Maven 3.3.9. So make sure you have JDK 7 installed. 
  • Set JAVA_HOME env variable to above JDK. For me it is C:\Program Files\Java\jdk1.7.0_79
  • Also I am using Windows 7.

How to install Maven on Windows

  • Download Maven zip file from their official site. We are going to install Maven 3.3.9. So go ahead download the corresponding zip file -
  • Unzip it to some folder.  I have extracted it in folder - C:\Users\athakur\Softwares\apache-maven-3.3.9
  • Now add M2_HOME and MAVEN_HOME environment variable and point them to your extracted folder.
  • Append your %PATH% variable to add %M2_HOME%\bin
  • Make sure your JAVA_HOME is set to JDK 7 as per note below.
  • Finally you can execute mvn -version to see if maven is successful installed.

NOTE : Maven 3.3 requires JDK 1.7 or above to execute. Maven 3.2 requires JDK 1.6 or above, while Maven 3.0/3.1 requires JDK 1.5 or above

Serving static resources with Spring MVC 3.0 in Java


Many time we use custom CSS and java script file to add functionality and style to our web pages. We usually refer them in our JSP pages. In this post we will see how we can refer such static resources with Spring 3.0+. We will use Tomcat as our container/server.


If you are new to Spring then try out a sample Spring program -
Above post is somewhat old but should give you good idea as to get started. Anyhow I will provide the setup xmls here.

Your web.xml file should look as follows -

<web-app id="WebApp_ID" version="2.4"

  <display-name>Spring Web MVC Demo Application</display-name>




 Important file here is mvc-dispatcher-servlet.xml which forms a part of web application context. Have given a dummy file root-context.xml for root application context but you may not add it in your web.xml file. If you are not familiar with context loading part I suggest read

As I said create file mvc-dispatcher-servlet.xml with following content -

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns=""

    <bean id="viewResolver"
        <property name="prefix">
        <property name="suffix">
    <!-- Scan for components under this package -->
    <context:component-scan base-package="com.osfg.test" />


As you can see the web application context will scan package com.osfg.test to find Spring resources like handler/interceptor. GO ahead create this package and create a controller in it. Lets call it Add following content to it.

package com.osfg.test;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

 * @author athakur
public class TestController {
    @RequestMapping(value="/test", method=RequestMethod.GET)
    public String welcome() {
        return "test";


That's it. We have our controller all setup. This controller returns a logical view name called test. Now if you notice our spring configuration we have already defined InternalResourceViewResolver which provides a JSTL view. So go ahead and create a JSP file at /pages/test.jsp under webapp or webcontent.

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "">
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>OSFG Test Page</title>
<link href="CSS/test.css" rel="stylesheet">

<h1>Hello World from OSFG!</h1>


As you can see our JSP references a CSS file called test.css. Create a folder called CSS and then create a file called test.cs  in it. Add following contents to it.
H1 {
color: white; background: teal; FONT-FAMILY: arial; FONT-SIZE: 18pt; FONT-STYLE: normal; FONT-VARIANT: normal

Ok we are all set to test now.

Note the Directory structure below -


Testing 1.0

Go ahead start up your tomcat server and load following URL
  • http://localhost:8080/TestWebProject/test 

 Oops! what happened? It is not able to find the CSS file.Well lets come to the point. Spring does not directly allow you to access static resources and the very goal of this post is to show you how. So lets see that now.

Add following to your Spring configuration -
<mvc:default-servlet-handler />

This basically allows you to render static resources from root folder (under webapp or webcontent).
It essentially configures a handler for serving static resources by forwarding to the Servlet container's default Servlet (DefaultServletHttpRequestHandler is used).
 Lets test with our new configuration -

Testing 2.0

After restarting the server hit the URL again -

All good? Yup :) There is also alternate way to do this. You can define resource mapping instead of specifying default-servlet-handler.

<mvc:resources mapping="/resources/**" location="/CSS/" />

Then you also need to make change in JSP as follows

<link href="resources/test.css" rel="stylesheet">

So when you reference resources it will go and pick up from CSS. You can use classpath references in location as well. Here ResourceHttpRequestHandler is used to serve request based on location provided.
