Overview
The annotation may also contain a sub-path relative to the class-level base path, usually configured with @RequestMapping.
REST
@RestController
@RequestMapping(path = "/a", produces = "application/json")
public class AController {
@PutMapping(path = "/{id}", consumes = "application/json")
public ResponseEntity<A> put(@PathVariable("id") Integer id, @RequestBody A a) {
// wholesale replacement, make sure there is such an ID and the A instance is valid
A old = content.get(id);
if (old == null) {
return new ResponseEntity<>(null, HttpStatus.NOT_FOUND);
}
old.updateFrom(a);
return new ResponseEntity<>(old, HttpStatus.OK);
}
}
