Spring Framework 4.3 has introduced few convenient annotations for HTTP Request Mapping based on the HTTP Request Method.
| Old Way | New Way |
| @RequestMapping(value = “/test”, method = RequestMethod.GET) | @GetMapping(“/api/customers”) |
| @RequestMapping(value = “/test”, method = RequestMethod.POST) | @PostMapping(“/api/create”) |
| @RequestMapping(value = “/test”, method = RequestMethod.PUT) | @PutMapping(“/api/update”) |
| @RequestMapping(value = “/test”, method = RequestMethod.DELETE) | @DeleteMapping(“/api/delete”) |
| @RequestMapping(value = “/test”, method = RequestMethod.PATCH) | @PatchMapping(“/api/update”) |
Here is the Sample code
@RestController
public class RestApiController
{
@GetMapping(value = "/user")
public String getMappingExample()
{
return "HTTP GET : Request Mapping";
}
@PostMapping(value = "/user")
public String postMappingExample()
{
return "HTTP POST : Request Mapping";
}
@PutMapping(value = "/user")
public String putMappingExample()
{
return "HTTP PUT : Request Mapping";
}
@DeleteMapping(value = "/user")
public String deleteMappingExample()
{
return "HTTP DELETE : Request Mapping";
}
}
