Spring Boot ResponseEntity

last modified July 6, 2020

Spring Boot ResponseEntity tutorial shows how to use ResponseEntity in a Spring application.

Spring is a popular Java application framework and Spring Boot is an evolution of Spring that helps create stand-alone, production-grade Spring based applications easily.


ResponseEntity represents an HTTP response, including headers, body, and status. While @ResponseBody puts the return value into the body of the response, ResponseEntity also allows us to add headers and status code.

Spring Boot ResponseEntity example

In the following application, we demonstrate the usage of ResponseEntity. The application has two methods: one method uses ResponseEntity to create an HTTP response, the other one @ResponseBody.

│   ├───java
│   │   └───com
│   │       └───zetcode
│   │           │   Application.java
│   │           ├───controller
│   │           │       MyController.java
│   │           └───model
│   │                   Country.java
│   └───resources
│       └───static
│               index.html

This is the project structure of the Spring application.

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"






This is the Maven pom.xml file. The spring-boot-starter-parent is a parent POM providing dependency and plugin management for applications built with Maven. The spring-boot-starter-web is a dependency for creating Spring Boot web applications using Spring MVC. The spring-boot-maven-plugin packages Spring applications into executable JAR or WAR archives.

package com.zetcode.model;

public class Country {
    private String name;
    private int population;

    public String getName() {
        return name;

    public void setName(String name) {
        this.name = name;

    public int getPopulation() {
        return population;

    public void setPopulation(int population) {
        this.population = population;

This is the Country bean. It has two attributes: name and population.

package com.zetcode.controller;

import com.zetcode.bean.Country;
import org.springframework.http.HttpHeaders;
import org.springframework.http.ResponseEntity;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

public class MyController {
    @RequestMapping(value = "/getCountry")
    public ResponseEntity<Country> getCountry() {
        var c = new Country();
        var headers = new HttpHeaders();
        headers.add("Responded", "MyController");
        return ResponseEntity.accepted().headers(headers).body(c);
    @RequestMapping(value = "/getCountry2")
    public Country getCountry2() {
        var c = new Country();
        return c;

The controller contains two methods. The first one uses ResponseEntity, the second one @ResponseBody.

@RequestMapping(value = "/getCountry")
public ResponseEntity<Country> getCountry() {

The getCountry() method is mapped to the getCountry URL pattern; it returns a ResponseEntity of type Country.

var c = new Country();

We create a Country bean; this bean is returned in the response.

var headers = new HttpHeaders();
headers.add("Responded", "MyController");

We create an instance of HttpHeaders and add a new header value.

return ResponseEntity.accepted().headers(headers).body(c);

A ResponseEntity is returned. We give ResponseEntity a custom status code, headers, and a body.

@RequestMapping(value = "/getCountry2")
public Country getCountry2() {
    var c = new Country();
    return c;

With @ResponseBody, only the body is returned. The headers and status code are provided by Spring.

<!DOCTYPE html>
        <title>Home page</title>
        <meta charset="UTF-8">
        <meta name="viewport" content="width=device-width, initial-scale=1.0">
            <a href="getCountry">Get country 1</a>
            <a href="getCountry2">Get country 2</a>

This is the home page. It contains two links.

package com.zetcode;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

public class Application  {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);

Application is the entry point which sets up Spring Boot application.

$ curl localhost:8080/getCountry -I
HTTP/1.1 202
Responded: MyController
Content-Type: application/json;charset=UTF-8
Transfer-Encoding: chunked
Date: Thu, 17 Jan 2019 21:40:49 GMT

When calling the first method, we can see the chosen 202 status code and the custom header value.

In this tutorial, we have shown how to use ResponseEntity in a Spring application.
