Method not allowed "Request method 'PUT' not supported"

Olá, estou recebendo o seguinte erro:

{timestamp: 1512065616839, status: 405, error: "Method Not Allowed",…}
error:"Method Not Allowed"
exception:"org.springframework.web.HttpRequestMethodNotSupportedException"
message:"Request method 'PUT' not supported"
path:"/api/v1/products/1"
status:405
timestamp:1512065616839

com o seguinte header

Access-Control-Allow-Credentials:true
Access-Control-Allow-Origin:http://localhost:4200
Allow:DELETE, GET
Cache-Control:no-cache, no-store, max-age=0, must-revalidate

claramente o método PUT não está habilitado. Gostaria de saber como habilitá-lo.

Esse é o meu controller

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;

@RestController

public class ProductsController {

    @Autowired
    private ProductsService productsService;

    @GetMapping(produces = MediaType.APPLICATION_JSON_VALUE)
    public ResponseEntity<List<Products>> all() {

        List<Products> products = this.productsService.getAll();

        return new ResponseEntity<List<Products>>(products, HttpStatus.OK);
    }

    @PostMapping(consumes = MediaType.APPLICATION_JSON_VALUE)
    public ResponseEntity<Products> register(@RequestBody Products product) {

        Products productSaved = productsService.register(product);

        return new ResponseEntity<Products>(productSaved, HttpStatus.CREATED);
    }

    @DeleteMapping("/{id}")
    public ResponseEntity<Products> removeProduct(@PathVariable("id") Integer id) {

        Products productFound = productsService.findById(id);
        if (productFound == null) {
            return new ResponseEntity<>(HttpStatus.NOT_FOUND);
        }

        productsService.remove(productFound);

        return new ResponseEntity<Products>(HttpStatus.OK);
    }

    @GetMapping("/{id}")
    public ResponseEntity<Products> findById(@PathVariable("id") Integer id) {

        Products productFound = productsService.findById(id);
        if (productFound == null) {
            return new ResponseEntity<>(HttpStatus.NOT_FOUND);
        }

        return new ResponseEntity<Products>(productFound, HttpStatus.OK);
    }

    @PutMapping(consumes = MediaType.APPLICATION_JSON_VALUE, produces = MediaType.APPLICATION_JSON_VALUE)
    public ResponseEntity<Products> modify(@RequestBody Products product) {

        Products productChanged = productsService.modify(product);

        return new ResponseEntity<Products>(productChanged, HttpStatus.OK);
    }
}

Obrigado!
