Understanding HTTP Status Codes in Spring Boot REST API | HTTP Status Codes |
To begin, familiarize yourself with HTTP status codes. When a server responds to a request, it includes a status code that indicates the outcome. A status code is a 3-digit number, such as 200 or 404. HTTP status codes are categorized into five groups:
1xx (Informational): Request received, continuing process.
2xx (Successful): The request was successfully received, understood, and accepted.
3xx (Redirection): Further action needs to be taken to complete the request.
4xx (Client Error): The request contains bad syntax or cannot be fulfilled.
5xx (Server Error): The server failed to fulfill an apparently valid request.
