Spring Boot, Spring Security, PostgreSQL: JWT Authentication & Authorization example

User Registration, User Login and Authorization process.

The diagram shows flow of how we implement User Registration, User Login and Authorization process.

Spring Boot Server Architecture with Spring Security

You can have an overview of our Spring Boot Server with the diagram below:

Configure Spring Datasource, JPA, App properties

Open src/main/resources/application.properties

spring.datasource.url= jdbc:postgresql://localhost:5432/testdb
spring.datasource.username= postgres
spring.datasource.password= 123

spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation= true
spring.jpa.properties.hibernate.dialect= org.hibernate.dialect.PostgreSQLDialect

# Hibernate ddl auto (create, create-drop, validate, update)
spring.jpa.hibernate.ddl-auto= update

# App Properties
bezkoder.app.jwtSecret= ======================BezKoder=Spring===========================
bezkoder.app.jwtExpirationMs= 86400000

Run Spring Boot application

mvn spring-boot:run

Run following SQL insert statements

INSERT INTO roles(name) VALUES('ROLE_USER');
INSERT INTO roles(name) VALUES('ROLE_MODERATOR');
INSERT INTO roles(name) VALUES('ROLE_ADMIN');
