What is the status of RestTemplate in recent Spring versions?
Відповідь
RestTemplate has been in maintenance mode since Spring 5 and is no longer actively developed. Spring recommends using WebClient, a more modern and performant non-blocking reactive API. RestTemplate remains supported for compatibility with existing code, but new projects should prefer WebClient.
2Which RestTemplate method returns only the response body?
Which RestTemplate method returns only the response body?
Відповідь
getForObject directly returns the deserialized object from the HTTP response body, without metadata (status, headers). This method is convenient for simple cases where only data is needed. To access headers or HTTP status, use getForEntity which returns a complete ResponseEntity.
3Which RestTemplate method allows access to the HTTP status and response headers?
Which RestTemplate method allows access to the HTTP status and response headers?
Відповідь
getForEntity returns a ResponseEntity that encapsulates the response body, HTTP status code and headers. This method is useful when it's necessary to inspect response metadata, such as checking the status or reading a custom header. For simple cases where only the body is needed, getForObject is sufficient.
