Build & Test REST APIs with POSTMAN and Spring Boot

EDUCBA uses an employee-management application to connect Spring Boot structure with REST endpoints and Postman checks. CRUD behavior, exceptions and configuration make the example more than a single successful request. It suits learners who want to understand how a Java backend and its tests agree on the meaning of a response, including when a record does not exist or input is invalid.

What you will learn

• Structure a Spring Boot REST application.
• Implement CRUD operations and exception handling.
• Validate endpoint behavior using Postman.

Who this suits

Beginner by the provider’s label, with Java and backend familiarity useful for following the application code. The focus includes both Spring Boot development and Postman testing rather than Postman alone.

Before you enroll

Practice against a local or explicitly permitted API with fictional records. Keep tokens and credentials out of shared collections, repositories, screenshots and exported request logs. Match examples with the current Postman interface and plan limits; cloud collaboration or other tools may cost extra. A successful response is only one test outcome: consider invalid input, permissions and repeatable execution before relying on a collection.

Put it into practice

Implement a fictional employee lookup and test it with Postman. Compare an existing identifier, a missing record and malformed input, then explain which HTTP response each case should produce and why.
