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');
