Spring MVC - Generate XML Example

The following example shows how to generate XML using the Spring Web MVC Framework. To begin with, let us have a working Eclipse IDE in place and stick to the following steps to develop a Dynamic Form based Web Application using the Spring Web Framework.

User.java

package com.howcodex;

import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name = "user")
public class User {
   private String name;
   private int id;
   public String getName() {
      return name;
   }
   @XmlElement
   public void setName(String name) {
      this.name = name;
   }
   public int getId() {
      return id;
   }
   @XmlElement
   public void setId(int id) {
      this.id = id;
   }	
}

UserController.java

package com.howcodex;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
@RequestMapping("/user")
public class UserController {
	
   @RequestMapping(value="{name}", method = RequestMethod.GET)
   public @ResponseBody User getUser(@PathVariable String name) {

      User user = new User();

      user.setName(name);
      user.setId(1);
      return user;
   }
}

TestWeb-servlet.xml

<beans xmlns = "http://www.springframework.org/schema/beans"
   xmlns:context = "http://www.springframework.org/schema/context"   
   xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance"
   xmlns:mvc = "http://www.springframework.org/schema/mvc"
   xsi:schemaLocation = "
   http://www.springframework.org/schema/beans     
   http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
   http://www.springframework.org/schema/context 
   http://www.springframework.org/schema/context/spring-context-3.0.xsd
   http://www.springframework.org/schema/mvc
   http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
   <context:component-scan base-package = "com.howcodex" />
   <mvc:annotation-driven />
</beans>

Here, we have created an XML Mapped POJO User and in the UserController, we have returned the User. Spring automatically handles the XML conversion based on RequestMapping.

Once you are done with creating source and configuration files, export your application. Right click on your application, use Export → WAR File option and save your TestWeb.war file in Tomcat's webapps folder.

Now, start the Tomcat server and make sure you are able to access other webpages from the webapps folder using a standard browser. Try a URL – http://localhost:8080/TestWeb/mahesh and we will see the following screen.
