Top 10 Features/Skills Every Spring Boot Java Developer Should Know as a Team Lead

1. Core Spring Boot Fundamentals

• Dependency Injection (DI): Understand and efficiently use Spring's core feature for managing beans and dependencies.
• Spring Boot Auto-Configuration: Leverage auto-configuration to simplify application setup.
• Profiles and Configuration: Master environment-specific configurations using profiles (application-{profile}.properties) and externalized configuration.

2. Advanced Spring Boot Configuration

• Custom Starters: Create custom Spring Boot starters for reusable components across multiple projects.
• Health Checks and Monitoring: Use Spring Boot Actuator to monitor application health, expose custom metrics, and build observability into microservices.

3. REST API Development

• Spring MVC: Deep knowledge of controllers, request mappings, and response entities.
• Validation: Implement robust input validation with @Valid and custom validators.
• HATEOAS: Understand how to make APIs self-descriptive and navigable.
