Figure 7.1

Now enable Maven by right-clicking the project in the Project Explorer and selecting Configure – “Convert to Maven Project” (This is for the new m2e plugin. For the old m2eclipse plugin this is Maven – “Enable Dependency Management”) as shown in Figure 7.2

Figure 7.2

Enter all details as required and remember to make sure the packaging type to war as shown in Figure 7.3

Figure 7.3

Now write the following code in pom.xml to add Spring Dependency in project.

<properties>
    <spring.version>3.0.5.RELEASE</spring.version>
</properties>
 
<dependencies>
 
    <!-- Spring 3 dependencies -->
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-core</artifactId>
        <version>${spring.version}</version>
    </dependency>
 
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-web</artifactId>
        <version>${spring.version}</version>
    </dependency>
 
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-webmvc</artifactId>
        <version>${spring.version}</version>
    </dependency>
 
</dependencies>

1. Create Controller

Now create HelloWorldController in com.kruders.controller package and write the following code.

package com.kruders.controller;
 
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
 
@Controller
@RequestMapping("/helloworld.html")
public class HelloWorldController {
    @RequestMapping(method = RequestMethod.GET)
    public String printWelcome(ModelMap model) {
 
        model.addAttribute("message", "Hello World!!!");
        return "helloworld";
 
    }
}

2. Create View

Create jsp folder in WEB-INF and create helloworld.jsp file in jsp folder

Now write the following code in helloworld.jsp file

${message}

3. Configuration

Create Spring Bean Configuration in WEB-INF folder and name it dispatcher-servlet.xml and add the following code.

<context:component-scan base-package="com.kruders.controller" />
 
<bean
    class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix">
        <value>/WEB-INF/jsp/</value>
    </property>
     
    <property name="suffix">
        <value>.jsp</value>
    </property>
</bean>

4. Integrate Spring in Web App

To integrate Spring in Web Application, write the following code in web.xml

<servlet>
    <servlet-name>dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
 
<servlet-mapping>
    <servlet-name>dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>
 
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/dispatcher-servlet.xml</param-value>
</context-param>
 
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

5. Add Maven Dependency
