Add dependencies: web, Lombok

In addition to the above dependencies, we have to add the Jackson DataFormat XML dependency

Directory Structure:

Employee.java

package com.example.demo.entity;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@AllArgsConstructor
@NoArgsConstructor
public class Employee {

    private Integer empNo;
    private String ename;
    private String dept;
    private Float sal;
}

EmployeeController.java

package com.example.demo.controller;

import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

import com.example.demo.entity.Employee;

@RestController
public class EmployeeController {

    @GetMapping("/display")
    public ResponseEntity<Employee> showData() {
        Employee emp = new Employee(201,"Carla","DEV",4500.0f);
        return new ResponseEntity<Employee>(emp,HttpStatus.OK);
    }
}

Run the Application

Open Postman

Enter URL

go to the header and do some modifications

This is a way we can get xml response from rest api in spring boot
