Quick Setup (5 Minutes)

1. Prerequisites

• Java 17+
• PostgreSQL (running)
• Maven

2. Clone the Project

git clone https://github.com/subhashree0454/Task-Manager.git
cd Task-Management

3. Setup PostgreSQL Database

CREATE DATABASE taskflow_db;
CREATE USER taskflow_user WITH PASSWORD 'yourpassword123';
GRANT ALL PRIVILEGES ON DATABASE taskflow_db TO taskflow_user;

4. Configure Database (application.properties)

spring.datasource.url=jdbc:postgresql://localhost:5432/task
spring.datasource.username=postgres
spring.datasource.password=123
spring.datasource.driver-class-name=org.postgresql.Driver

spring.jpa.hibernate.ddl-auto=update
spring.jpa.show-sql=true
spring.jpa.database-platform=org.hibernate.dialect.PostgreSQLDialect

5. Production Configuration (Environment Variables)

For security, avoid hardcoding credentials. You can override properties using Environment Variables:

Variable	Description
SPRING_DATASOURCE_URL	DB Connection String
SPRING_DATASOURCE_USERNAME	DB Username
SPRING_DATASOURCE_PASSWORD	DB Password

Example:

export SPRING_DATASOURCE_URL=jdbc:postgresql://your-host:5432/task_db
export SPRING_DATASOURCE_USERNAME=prod_user
export SPRING_DATASOURCE_PASSWORD=secure_password123

6. Run the App

./mvnw spring-boot:run

Open → http://localhost:8080

7. Development Tips

• DevTools: The project includes spring-boot-devtools, so changes will trigger an automatic restart.
• Port: To change the default port, add -Dspring-boot.run.arguments=--server.port=9090 to the run command.
• Database Reset: Change spring.jpa.hibernate.ddl-auto to create-drop in application.properties to clear the DB on every restart (careful!).
