What is the restTemplate.exchange() method for?

Question

Actually what does the restTemplate.exchange() method do?

@RequestMapping(value = \"/getphoto\", method = R         


        

Answer 1

The more generic exchange API requires a HttpMethod parameter and a request object for completeness. Compare:

ResponseEntity response = 
restTemplate.exchange(url, HttpMethod.GET, request, Foo.class);

ResponseEntity response = 
restTemplate.getForEntity(url, Foo.class);
