A view page is redirected to another view page in this example. Let’s look at a simple Spring Web MVC framework sample. The procedure is as follows:
- In the case of Maven, load the spring jar files or add dependencies.
- Make your controller class.
- Provide a controller entry in the web.xml file.
- In a separate XML file, define the bean.
- Make the rest of the view components.
- Start the server and make the project available.
Example Project
Project structure:
Step 1. Add dependencies to pom.xml
You can download the required dependencies from URLs given in the comments of the program.
XML
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 <modelVersion>4.0.0</modelVersion> <groupId>com.neveropen</groupId> <artifactId>SpringMVCMultipleViewPage</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>SpringMVCMultipleViewPage Maven Webapp</name> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>5.1.1.RELEASE</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>3.0-alpha-1</version> </dependency> </dependencies> <build> <finalName>SpringMVCMultipleViewPage</finalName> </build></project> |
Step 2. Make your request page
Let’s start by making a simple jsp page with a link.
index.jsp
HTML
<html><body> <a href="hello">Click here to go next...</a></body></html> |
Step 3. Develop a controller class
Let’s start by developing a controller class that returns JSP pages. To map the class, we supply the exact name using a @Requestmapping annotation.
GfgController.java
Java
package com.neveropen;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;@Controllerpublic class GfgController{ @RequestMapping("/hello") public String redirect() { return "viewpage"; } @RequestMapping("/helloagain") public String display() { return "final"; }} |
Step 4. Provide the entry of controller in the web.xml file
web.xml
XML
<?xml version="1.0" encoding="UTF-8"?><web-app> <display-name>SpringMVC</display-name> <servlet> <servlet-name>spring</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>spring</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app> |
Step 5. In the XML file, define the bean
- We now provide a view resolver with the view component.
- For the ViewResolver, the InternalResourceViewResolver class is utilized.
- For the view component, the prefix+string returned by the controller+suffix page will be used.
- This XML file should be placed in the WEB-INF folder.
spring-servlet.xml
XML
<?xml version="1.0" encoding="UTF-8"?> xsi:schemaLocation=" <!-- Add support for component scanning --> <context:component-scan base-package="com.neveropen" /> <!--Add support for conversion, formatting and validation --> <mvc:annotation-driven/> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/jsp/"></property> <property name="suffix" value=".jsp"></property> </bean> </beans> |
Step 6. Create the other view components
viewpage.jsp
HTML
<html><body> <a href="helloagain">We are going to visit GeeksForGeeks</a></body></html> |
final.jsp
HTML
<html><body> <p>Welcome to GeeksForGeeks</p></body></html> |
Output:
After clicking the “Click here to go next…” link following page will be shown
And after clicking on the above link this page will be shown
