Spring Boot JWT Authentication example with Spring Security & Spring Data JPA
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:
Dependency
– If you want to use PostgreSQL:
<dependency>
<groupId>org.postgresql</groupId>
<artifactId>postgresql</artifactId>
<scope>runtime</scope>
</dependency>– or MySQL:
<dependency>
<groupId>com.mysql</groupId>
<artifactId>mysql-connector-j</artifactId>
<scope>runtime</scope>
</dependency>Configure Spring Datasource, JPA, App properties
Open src/main/resources/application.properties
- For PostgreSQL:
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= bezKoderSecretKey
bezkoder.app.jwtExpirationMs= 86400000
- For MySQL
spring.datasource.url=jdbc:mysql://localhost:3306/testdb_spring?useSSL=false
spring.datasource.username=root
spring.datasource.password=123456
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQLDialect
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');
