HOW TO USE?

Step-1: Fistly you need to set-up your database. Make sure you have MySQL installed in your PC.
Database Setup : to setup your database you can use the file database/boot_crud_db.sql. using phpmyadmin = if you are using php myadmin then simpley create a new database with the name of 'chat' and then you can import file database/boot_crud_db.sql from your import tab.

using mysql command line client OR workbench - you can simple run the given queries to create your database setup:

creating a database :

CREATE DATABASE boot_crud_db;

using the database :

USE boot_crud_db;

creating database table :

CREATE TABLE `users` (
  `id` bigint(20) NOT NULL,
  `dob` date DEFAULT NULL,
  `email` varchar(255) DEFAULT NULL,
  `name` varchar(255) DEFAULT NULL,
  `password` varchar(255) DEFAULT NULL,
  `image` varchar(255) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1 COLLATE=latin1_swedish_ci;

add primary key and other constraints :

ALTER TABLE `users`
  ADD PRIMARY KEY (`id`),
  ADD UNIQUE KEY `UK6dotkott2kjsp8vw4d0m25fb7` (`email`);

set the unique id to handle big requests as well:

ALTER TABLE `users`
  MODIFY `id` bigint(20) NOT NULL AUTO_INCREMENT, AUTO_INCREMENT=40;
COMMIT;

dummy data:

INSERT INTO `users` (`id`, `dob`, `email`, `name`, `password`, `image`) VALUES
(20, '2024-02-23', 'raj@gmail.com', 'Raj kumar', '$2a$10$NI5IFvnLxpXlkjSplgsB2e2bOjHkEHtCZ7kfVzdRDPTVpJk9WH.Iu', 'cfb47473-369c-4be9-b3d0-a2bdbcdcfe38.jpg'),
(21, '2024-01-31', 'mysql@gmail.com', 'SpaceX', '$2a$10$9Oal.rc7J/0qewwsPbFOIuNgjTNGMRE2Zh1nxmY0CRTsiEK1IFRFO', 'adefefb9-b7c6-43d6-a661-c4a1ae42cc53.png');

Step-2: open your STS IDE import this project as an existing maven project
file->import->existing maven project-> choose project folder and hit enter

This will open that project in your ide

Step-3: To run this application firstly you need to update your build and update your newly opened maven project.
To do this right click on your project -> build project
after this in order to update your maven project, again right click on your project-> maven -> update project

Step-4: Now you are ready to run this crud-application
right click on this java class => src/main/java/com/crudapp/SpringBootCrudApplication.java -> Run As -> Spring boot application
It will take few seconds to launch the applications. after launching you can browser this url [ http://localhost:8080] on your browser to show application


NOTE - if you are configuring this type of project first time, you may face many errors, my suggestion is - to run application - and check the browser with this URL [ http://localhost:8080] . If this page is available that means your errors are minor and you are able to run this applicaton
In my case this is working just fine!
