: Combines @Controller and @ResponseBody , signaling that the class handles web requests and returns data (like JSON) directly.
: Allows you to control the full HTTP response, including the status code (e.g., 201 Created ), headers, and body. Implementation Best Practices For a "solid" implementation, consider these factors:
: Maps the incoming HTTP request body directly to a Java object, automatically handling deserialization (usually from JSON) via libraries like Jackson . Spring REST
: Return a 201 Created status for successful creations rather than a generic 200 OK .
To build a solid POST endpoint, you generally use several key annotations and classes: : Combines @Controller and @ResponseBody , signaling that
: It is often best to use DTOs rather than exposing your database entities directly to the API.
Handling in Spring REST is a core skill for building modern APIs. In Spring, the POST method is used to send new data to a server, typically to create a new resource . Key Components for a POST Endpoint : Return a 201 Created status for successful
: Implement a global exception handler (using @ControllerAdvice ) to return consistent error responses when a POST fails. Consuming POST Services
