Note: Alternatively, tables are auto-created by Hibernate (ddl-auto=update) on first application startup.

4. Configure Database Credentials

Edit src/main/resources/application.properties if your MySQL credentials differ from the defaults:

spring.datasource.url=jdbc:mysql://localhost:3306/university_db?createDatabaseIfNotExist=true&useSSL=false&serverTimezone=UTC&allowPublicKeyRetrieval=true
spring.datasource.username=root
spring.datasource.password=root

5. Build the Project

mvn clean package -DskipTests

🔒 Security Considerations

Implemented Security Measures

1. Input Validation

   • Bean Validation annotations
   • SQL injection prevention
   • XSS protection

2. Authentication & Authorization

   • Form-based authentication (planned)
   • Role-based access control (future)
   • Session management

3. Data Protection

   • Password hashing (BCrypt)
   • Sensitive data encryption
   • Audit logging

Security Best Practices

// Example: Secure password handling
@Service
public class UserService {
    
    private final BCryptPasswordEncoder passwordEncoder = new BCryptPasswordEncoder();
    
    public void createUser(UserDto userDto) {
        User user = new User();
        user.setPassword(passwordEncoder.encode(userDto.getPassword()));
        // ... other fields
        userRepository.save(user);
    }
}

Security Headers

# Security headers configuration
security.headers.frame-options=DENY
security.headers.content-type-options=nosniff
security.headers.xss-protection=1; mode=block

---

🔧 Troubleshooting

Common Issues

1. Database Connection Failed

Symptoms: Application fails to start with database errors

Solutions:

# Check MySQL service
sudo systemctl status mysql

# Verify database exists
mysql -u root -p -e "SHOW DATABASES;"

# Check credentials
mysql -u dums_user -p university_db

# Reset password if needed
ALTER USER 'dums_user'@'localhost' IDENTIFIED BY 'NewPassword123!';

2. Port Already in Use

Symptoms: "Address already in use" error

Solutions:

# Find process using port
sudo lsof -i :8080

# Kill process
sudo kill -9 <PID>

# Or change port in application.properties
server.port=8081

3. Memory Issues

Symptoms: OutOfMemoryError

Solutions:

# Increase heap size
java -Xmx2g -Xms1g -jar DUMS.jar

# Or in application.properties
spring.jpa.properties.hibernate.jdbc.batch_size=20

Performance Issues

Slow Database Queries

-- Enable slow query log
SET GLOBAL slow_query_log = 'ON';
SET GLOBAL long_query_time = 1;
