Spring MVC - Generate XML Example

The following example shows how to generate XML using the Spring Web MVC Framework.

To start with, let us have a working Eclipse IDE in place and consider the following steps to develop a Dynamic Form based Web Application using Spring Web Framework −

User.java

package com.tutorialspoint;

import jakarta.xml.bind.annotation.XmlElement;
import jakarta.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.tutorialspoint;

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

@Controller
public class UserController {
	
   @GetMapping("/user/{name}")
   public @ResponseBody User getUser(@PathVariable("name") String name) {

      User user = new User();

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

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.

Output

Once you are done with creating source and configuration files, export your application. Right click on your application, use Run As → Maven Install option and save your hello.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/hello/user/mahesh and we will see the following screen.
