Spring Boot – RESTful Web Service with POST Request in JSON Example

Spring-Boot-Tutorials » on May 24, 2018 { 11 Comments } By Sivateja

In the previous articles I didn’t get a chance to use the POST request in the examples, but this is very important. In this article I am going to show you how to create a Spring Boot REST service with POST request in JSON format with a simple example.

As Spring Boot by default supports JSONΒ request and responses, we no need to add any dependencies. A simple annotation called @RequestBody will do the trick for us πŸ˜‰


    xmlns:xsi="" xsi:schemaLocation="">


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

public class SpringBootApp {
    public static void main(String[] args) {, args);


package com.java4s.model;

public class Customer {

    private int custNo;
    private String name;
    private String country;

    public Customer() {


    public Customer(int custNumber, String name, String country) {
        this.custNo = custNumber; = name; = country;

    public int getCustNo() {
        return custNo;

    public void setCustNo(int custNo) {
        this.custNo = custNo;

    public String getName() {
        return name;

    public void setName(String name) { = name;

    public String getCountry() {
        return country;

    public void setCountry(String country) { = country;


import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;

import com.java4s.model.Customer;

public class SpringJava4sController {

    @PostMapping(path = "/save-cust-info")
    public String customerInformation(@RequestBody Customer cust) {

        /* You can write your DAO logic here.
         * For time being I am printing the customer data just to show the POST call is working.

        return "Customer information saved successfully ::." + cust.getCustNo() + " " + cust.getName() + " " + cust.getCountry();



Run the application and open the URL in Postman


	"custNo" : 100,
	"name" : "Google",
	"country": "United States"

    I have got
    Whitelabel Error Page

    This application has no explicit mapping for /error, so you are seeing this as a fallback.
