Spring boot with Angular Full Stack Application

Spring Boot is a powerful java framework which allow the user to quickly build the application. This tutorial will teach you how to do the full stack development application using Spring boot with Angular that are CREATE, RETIEVE, UPDATE and DELETE and SEARCH using mysql Database.Spring Boot is the backend and Angular is a  frontend to perform CRUD Application Step by step.

Crud function how to perform the RESTful Web Service let discuss with following annotations.

@PostMapping:  annotation which used to create new record.
@GetMapping:   annotation which used to reads a record.
@RequestMapping: annotation which used to search the record.
@PutMapping:   annotation which used to update the existing record.
@DeleteMapping:  annotation which used to delete the record.

Lets Started Project

Spring Boot – Back End Application

Angular – Front End Application

Learns Start Spring Boot.

First Step visit to Spring Initializer to configure the project using the following dependencies.

Create the Package Customer Controller

Inside the Package create the class CustomerController.java

CustomerController.java

package com.Project.SpringAngular.CustomerController;
import com.Project.SpringAngular.DTO.CustomerDTO;
import com.Project.SpringAngular.DTO.CustomerSaveDTO;
import com.Project.SpringAngular.DTO.CustomerUpdateDTO;
import com.Project.SpringAngular.Service.CustomerService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

import java.util.List;

@RestController
@CrossOrigin
@RequestMapping("api/v1/customer")
public class CustomerController
{
    @Autowired
    private CustomerService customerService;

    @PostMapping(path = "/save")

    public String saveCustomer(@RequestBody CustomerSaveDTO customerSaveDTO)
    {
        String id = customerService.addCustomer(customerSaveDTO);
        return id;
    }

    @GetMapping(path = "/getAllCustomer")
    public List<CustomerDTO> getAllCustomer()
    {
       List<CustomerDTO>allCustomers = customerService.getAllCustomer();
       return allCustomers;
    }

    @PutMapping(path = "/update")

    public String updateCustomer(@RequestBody CustomerUpdateDTO customerUpdateDTO)
    {
        String id = customerService.updateCustomers(customerUpdateDTO);
        return id;
    }

    @DeleteMapping(path = "/deletecustomer/{id}")
    public String deleteCustomer(@PathVariable(value = "id") int id)
    {
        boolean deletecustomer = customerService.deleteCustomer(id);
        return "deleted";
    }

}

Create the Package entity

Inside the Package create the class Customer

package com.Project.SpringAngular.entity;

import javax.persistence.*;
@Entity
@Table(name = "customer")
public class Customer {
    @Id
    @Column(name = "customer_id", length = 50)
    @GeneratedValue(strategy = GenerationType.AUTO)
    private int customerid;

    @Column(name = "customer_name", length = 50)
    private String customername;

    @Column(name = "customer_address", length = 60)
    private String customeraddress;

    @Column(name = "mobile", length = 12)
    private int mobile;

    public Customer(int customerid, String customername, String customeraddress, int mobile) {
        this.customerid = customerid;
        this.customername = customername;
        this.customeraddress = customeraddress;
        this.mobile = mobile;
    }

    public Customer() {
    }

    public Customer(String customername, String customeraddress, int mobile) {
        this.customername = customername;
        this.customeraddress = customeraddress;
        this.mobile = mobile;
    }

    public int getCustomerid() {
        return customerid;
    }

    public void setCustomerid(int customerid) {
        this.customerid = customerid;
    }

    public String getCustomername() {
        return customername;
    }

    public void setCustomername(String customername) {
        this.customername = customername;
    }

    public String getCustomeraddress() {
        return customeraddress;
    }

    public void setCustomeraddress(String customeraddress) {
        this.customeraddress = customeraddress;
    }

    public int getMobile() {
        return mobile;
    }

    public void setMobile(int mobile) {
        this.mobile = mobile;
    }

    @Override
    public String toString() {
        return "Customer{" +
                "customerid=" + customerid +
                ", customername='" + customername + '\'' +

Create the Package Customer Service

Inside the Package create the interface CustomerService.java and CustomerServiceIMPL

import java.util.ArrayList;
import java.util.List;

@Service
public class CustomerServiceIMPL implements CustomerService
{
    @Autowired
    private CustomerRepo customerRepo;

    @Override
    public String addCustomer(CustomerSaveDTO customerSaveDTO)
    {
        Customer customer = new Customer(

                customerSaveDTO.getCustomername(),

            customer.setCustomername(customerUpdateDTO.getCustomername());
            customer.setCustomeraddress(customerUpdateDTO.getCustomeraddress());
            customer.setMobile(customerUpdateDTO.getMobile());
            customerRepo.save(customer);
        }
            else

            System.out.println("customer id not found");
        }

        return true;
    }
}

Create the Package Customer Controller

Inside the Package create the interface CustomerRepo.java

CustomerRepo.java

package com.Project.SpringAngular.CustomerRepo;

import com.Project.SpringAngular.entity.Customer;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import org.springframework.stereotype.Repository;

@EnableJpaRepositories
@Repository
public interface CustomerRepo extends JpaRepository<Customer,Integer> {
}

Do the Database Configuration in application.properties 

spring.application.name=crudnew
server.port=8084

spring.jpa.hibernate.ddl-auto=update
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

spring.datasource.url=jdbc:mysql://localhost:3306/gmsschool?createDatabaseIfNotExist=true
spring.datasource.username=root
spring.datasource.password=root

#jpa vendor adapter configuration
spring.jpa.database-platform=org.hibernate.dialect.MySQL57Dialect
spring.jpa.generate-ddl=true
spring.jpa.show-sql=true

Angular

Angular is a front-end application we have already created the folder front end inside the folder open the command prompt and type the commands.

Installing Angular CLI

npm install -g @angular/cli

After that create the new Project of Angular running by the following command

ng new frond-end

After complete the installation then run the project using following command.

ng serve

Now you see the Angular Welcome Page.

After that open the Angular project into VS code editor.

now you can see the following file structure

Creating a new Component Student Crud

ng g c customer

npm i bootstrap

@import "~bootstrap/dist/css/bootstrap.css";

FormModule
HttpClientModule

import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { BrowserModule } from '@angular/platform-browser';

import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { CustomerComponent } from './customer/customer.component';
import { HttpClientModule } from '@angular/common/http';

@NgModule({
  declarations: [
    AppComponent,
    CustomerComponent
  ],
  imports: [
    BrowserModule,
    AppRoutingModule,
    FormsModule,
    HttpClientModule

  
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

add these module into the app.module.ts file  then only we will manage the forms and Http requests
