Spring Boot GraphQL Save, Update and Delete - Database MutationMapping

noreply@blogger.com (Abdul Hakeem) — Thu, 18 Sep 2025 03:41:00 -0700

Learn how to get started with Graphql using spring boot framework. In this session, you will be learning like how to add the schema details and mapping the function and request payload with Graphql @MutationMapping into your controller class. So you can preform like Save, update and delete operation using graphql You need Spring web, JPA, Mysql, Lombok and Spring Graphql dependencies to your pom module.

schema.graphqls (This file should be created inside the resources/graphql folder)


type Query{
    findAll: [User]
    userById(id: ID): User
}

type User{
    id: ID
    name: String
    gender: String
    emailId: String
}

type Mutation{
    addUser(userDetails: UserDetails): User
    updateUser(userDetails: UserDetails): User
    deleteUser(id: ID): String
}

input UserDetails{
    id: ID
    name: String
    gender: String
    emailId: String
}

UserGQLController .java


package com.hakeemit.graphql.controller;

import com.hakeemit.graphql.entity.User;
import com.hakeemit.graphql.entity.UserDetails;
import com.hakeemit.graphql.service.UserServices;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.graphql.data.method.annotation.Argument;
import org.springframework.graphql.data.method.annotation.MutationMapping;
import org.springframework.graphql.data.method.annotation.QueryMapping;
import org.springframework.stereotype.Controller;

import java.util.List;

@Controller
public class UserGQLController {

    @Autowired
    private UserServices userServices;

    @QueryMapping
    public List findAll(){
        return userServices.getAllUser();
    }

    @QueryMapping
    public User userById(@Argument int id){
        return userServices.userById(id);
    }

    @MutationMapping
    public User addUser(@Argument UserDetails userDetails){
        return userServices.add(userDetails);
    }

    @MutationMapping
    public User updateUser(@Argument UserDetails userDetails){
        return userServices.update(userDetails);
    }

    @MutationMapping
    public String deleteUser(@Argument int id){
        return userServices.delete(id);
    }

}

@QueryMapping will be the entry point just like REST API Get Mapping.

    public User add(UserDetails userDetails){
        User user = new User();
        user.setName(userDetails.getName());
        user.setGender(userDetails.getGender());
        user.setEmailId(userDetails.getEmailId());
        return userRepositories.save(user);
    }

    public User update(UserDetails userDetails){

            user.get().setEmailId(userDetails.getEmailId());
            return userRepositories.save(user.get());
        }
        return null;
    }

    public String delete(int id){
        Optional user = userRepositories.findById(id);
        if(user.isPresent()) {
            userRepositories.delete(user.get());

noreply@blogger.com (Abdul Hakeem) — Wed, 17 Sep 2025 07:59:00 -0700

Learn how to connect to mysql database using spring boot framework. In this article you will learn the different types of @GetMapping/ @PostMapping / @PutMapping and @DeleteMapping Usages and their components @RestController, @Service, @Repository and @Entity.

Goto Spring Initializer https://start.spring.io/ and add the following dependencies like Spring web, JPA, lombok and mysql driver similar to below image

Generate the boilerplate code and open the project into your IDE.

Follow the below screenshot and create the respective packages to maintain your code easily.

noreply@blogger.com (Abdul Hakeem) — Wed, 17 Sep 2025 02:08:00 -0700

Learn How to get started with Spring boot framework. Create your very first REST API using Spring Boot and the @RestController @GetMapping annotation. Whether you're new to Java development or just getting started with Spring Boot, this step-by-step guide will help you understand the core concepts and build a simple "Hello World" RESTful API.

Go to Spring Initializer https://start.spring.io/

and fill out the following details similar to below image and add Spring web dependency

HelloController.java - Create new package and new class and add the following code into that class


package com.hakeemit.hello.controller;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class HelloController {

    @GetMapping("/hello")
    public String hello(){
        return "Hello World";
    }
}

Your project structure will look like this

Once you run the application. Go to http://localhost:8080/hello and you will be able to see the Hello World in the web browser.

Pride and Prejudice - Novel Review

noreply@blogger.com (Abdul Hakeem) — Tue, 5 Nov 2019 07:41:00 -0800

Book of the 18th century which made everyone fall crazy for Jane Austen.

Mr. Darcy became a role model for young men and a dream boy to every girl who read the book.

The language, the etiquette, the mannerism everything is bewitching and make you fall in love with Lizzy and Darcy.

Pride and Prejudice is a love story which leaves you feeling very warm and fuzzy on the inside; and also gives moral values to the reader. It emphasizes that girls need not be coquettish and simpering in order to find ardent lover. Any sensible man would want his wife to have some sense and intelligence. Hence women with intellect and courage are often found more attractive than empty-headed beauties. Good nature and character makes a lady look beautiful then any fashionable dress or makeup which is quite true in every Era.

Elizabeth Benet is a very mature girl with above mentioned qualities . Mr. Darcy seemingly proud and arrogant at first is remarkable good hear-ted and of reserved nature, so he considered proud by most of the novel's character. The story unfolds slowly and delves deeper into the characters' lives breaking down prejuidices along the way. It's not really a surprise that it is one of the most read classics in modern day. I would personally recommend each and every Austen's novel. It is a book worth treasuring forever.
