In this tutorial, we will learn how to build a full stack Angular 11 + Spring Boot + PostgreSQL example with a CRUD App. The back-end server uses Spring Boot with Spring Web MVC for REST Controller and Spring Data JPA for interacting with PostgreSQL database. Front-end side is made with Angular 11, HTTPClient & Router.
We will build a full-stack Tutorial Application in that:
– Add an object:
– Retrieve all Tutorials:
– Click on Edit button to go to a Tutorial page:
On this Page, you can:
– Search Tutorials by title:
– This is tutorials
table on the PostgreSQL database:
This is the application architecture we will build:
– Spring Boot exports REST Apis using Spring Web MVC & interacts with PostgreSQL Database using Spring Data JPA.
– Angular Client sends HTTP Requests and retrieve HTTP Responses using axios, shows data on the components. We also use Angular Router for navigating to pages.
This is our Angular Spring Boot CRUD application demo and brief instruction, running with PostgreSQL database:
In the video, we use Angular 10, but it has the same logic & UI as Angular version 11 in this tutorial.

In this tutorial, we will learn how to build a full stack Angular 12 + Spring Boot + PostgreSQL example with a CRUD App. The back-end server uses Spring Boot with Spring Web MVC for REST Controller and Spring Data JPA for interacting with PostgreSQL database. Front-end side is made with Angular 12, HTTPClient, Router and Bootstrap 4.

In this tutorial, we will learn how to build a full stack Spring Boot + Angular 12 example with a CRUD App. The back-end server uses Spring Boot with Spring Web MVC for REST Controller and Spring Data JPA for interacting with embedded database (H2 database). Front-end side is made with Angular 12, HttpClient, Router and Bootstrap 4.
Run both Project on same server/port:

In the tutorial, I introduce how to create an “SpringBoot Angular Postgresql CRUD Example” with POST/GET/PUT/DELETE requests to SpringBoot RestAPIs.
– Design overview system by Architecture Diagram that includes: Angular Client, SpringBoot RestAPIs, and Postgresql database.
– Implement Angular CRUD Client with Angular built-in HttpClient to communicate with server side.
– Implement SpringBoot RestAPIs that gets data from Postgresql using Spring Data JPA and returns back data as Json format to requested Angular Client.
We build backend SpringBoot Application that provides RestAPIs for POST/GET/PUT/DELETE Customer entities and store them in Postgresql/PostgreSQL database.
We implement Angular Application that use Angular HTTPClient to interact (call/receive requests) with SpringBoot backend and display corresponding page view in browser.
For building RestAPIs in SpringBoot application, we use Spring MVC Web.
For interacting with database Postgresql/PostgreSQL, we use Spring JPA.
We implement RestAPI’s URL in RestAPIController.java file to process bussiness logic.
For manipulating database’s records, we define a JPA model for mapping field data and use a JPA CRUD repository to do CRUD operation with Postgresql/PostgreSQL.
– SpringBoot Project Structure
models package defines Customer model and Message response class.
repository package defines Spring JPA repository class CustomerRepository to do CRUD operation with database.
service package defines a middleware class CustomerServices between Controller and Repository.
controller package defines a RestAPI Controller RestAPIController to handle POST/GET/PUT/DELETE request.
Angular CRUD Application (in “Angular 11 Spring Boot PostgreSQL CRUD Tutorial”) is designed with 3 main layers:
Service Layer is used to define Angular Common Services and HttpClient Services to interact with RestAPIs
Component Layer is used to define Angular Components to show views in Browser for interacting with Users
Router Layer is used to route URLs mapping with the corresponding Angular Components
Angular Project Structure:
Angular CRUD Application defines 3 components, 2 services, 1 routers, and 2 data models:
– Components:
add-customer component is used to add a new customer to system
list-customer component is used to show all customers on view pages, delete a customer and update a customer
message component is used to define a view to show logging message on browser
– Services:
customer.service.ts defines POST/GET/PUT/DELETE HTTP requests to SpringBoot RestAPIs with the built-in Angular HttpClient.
message.service.ts defines an array storage to log all messages when Angular CRUD App running
– Router: app-routing.module.ts defines how to map a corresponding Angular component with an URL.
– Models:
customer.ts defines the main data model of our application.
message.ts defines the response data model between SpringBoot and Angular application.
– Add new Customer: from Angular to SpringBoot and save to Postgresql.
– List All Customers: from Angular calls SpringBoot RestAPI to get customer from Postgresql.
– Details a Customer: from Angular calls get http request from SpringBoot RestAPI to get a record in Postgresql database
– Update a Customer: from Angular calls a put http request from SpringBoot RestAPI to update a record in Postgresql database.
– Delete a Customer: from Angular calls a delete http request from SpringBoot RestAPI to delete a record in Postgresql database.
– Check database records: do a get request from Angular to SpringBoot RestAPI.
