HTTP Verbs (GET, POST, PUT, PATCH, DELETE)

RESTful Conventions & Idempotency

RESTful web services use standard HTTP verbs to perform CRUD actions on resources.

Verb Properties:

• GET: Read resource. Safe & Idempotent.
• POST: Create new resource. Non-idempotent.
• PUT: Replace entire resource. Idempotent.
• PATCH: Modify partial fields. Non-idempotent.
• DELETE: Remove resource. Idempotent.

Production Code Example:

package com.anujsingh.digitalguru.controller;

import org.springframework.web.bind.annotation.*;

@RestController
@RequestMapping("/api/items")
public class RestEndpoints {
    @GetMapping return "Read";
    @PostMapping return "Create";
}

Key Architectural Concepts & Best Practices:

When working with HTTP Verbs (GET, POST, PUT, PATCH, DELETE) in enterprise Spring Boot applications, keep these key architectural guidelines in mind:

• Separation of Concerns: Maintain a strict boundary between HTTP endpoints, service logic, and database persistence layers.
• Framework Conventions: Rely on Spring Boot auto-configuration defaults whenever possible, overriding settings only via application.yml or @Configuration classes when customized behavior is required.
• Production Monitoring & Reliability: Ensure proper exception handling, thread-safety, and resource cleanup to prevent memory leaks and unexpected runtime downtime.
• Developer Ergonomics: Write clean, self-documenting code with modern Java features (Records, Lambdas, Streams) to simplify code reviews and maintenance.

Summary Takeaway:

Mastering HTTP Verbs (GET, POST, PUT, PATCH, DELETE) ensures that your Java & Spring Boot backend microservices remain maintainable, secure, and compliant with modern enterprise software engineering standards.
