Spring MVC - Multiple Controller

Last Updated : 02 Mar, 2022

We may construct numerous controllers at once in Spring MVC. Each controller class must be annotated with the @Controller annotation. A Spring MVC example with numerous controllers can be found here. 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

XML

<project xmlns="http://maven.apache.org/POM/4.0.0"          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"            xsi:schemaLocation="http://maven.apache.org/POM/4.0.0                               http://maven.apache.org/maven-v4_0_0.xsd">      <modelVersion>4.0.0</modelVersion>   <groupId>com.geeksforgeeks</groupId>   <artifactId>SpringMVCMultipleController</artifactId>   <packaging>war</packaging>   <version>0.0.1-SNAPSHOT</version>   <name>SpringMVCMultipleController Maven Webapp</name>   <url>http://maven.apache.org</url>   <dependencies>     <dependency>         <groupId>junit</groupId>         <artifactId>junit</artifactId>         <version>3.8.1</version>         <scope>test</scope>     </dependency>          <!-- https://mvnrepository.com/artifact/org.springframework/spring-webmvc -->     <dependency>         <groupId>org.springframework</groupId>         <artifactId>spring-webmvc</artifactId>         <version>5.1.1.RELEASE</version>     </dependency>      <!-- https://mvnrepository.com/artifact/javax.servlet/javax.servlet-api -->     <dependency>           <groupId>javax.servlet</groupId>           <artifactId>servlet-api</artifactId>           <version>3.0-alpha-1</version>         </dependency>         </dependencies>   <build>     <finalName>SpringMVCMultipleController</finalName>   </build> </project>

Step 2. Create the request page

Let's create a simple JSP page containing two links

index.jsp

HTML

<html> <body>   <a href="hello1">Geeksforgeeks Spring MVC Tutorials</a>  ||    <a href="hello2">Geeksforgeeks Spring Boot Tutorials</a> </body> </html>

Step 3. Develop a controller class

Let's make two controller classes, each of which returns a different view page.

GfgController1.java

Java

package com.geeksforgeeks; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping;  @Controller public class GfgController1 {        @RequestMapping("/hello1")     public String display()     {         return "gfgpage1";     }     }

GfgController2.java

Java

package com.geeksforgeeks; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping;  @Controller public class GfgController2 {        @RequestMapping("/hello2")     public String display()     {         return "gfgpage2";     }     }

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. Define the bean in the XML file

spring-servlet.xml

XML

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans"     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"      xmlns:context="http://www.springframework.org/schema/context"     xmlns:mvc="http://www.springframework.org/schema/mvc"     xsi:schemaLocation="         http://www.springframework.org/schema/beans         http://www.springframework.org/schema/beans/spring-beans.xsd         http://www.springframework.org/schema/context         http://www.springframework.org/schema/context/spring-context.xsd         http://www.springframework.org/schema/mvc         http://www.springframework.org/schema/mvc/spring-mvc.xsd">      <!-- Add support for component scanning -->     <context:component-scan base-package="com.geeksforgeeks" />      <!--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>
