swagger springfox - bean validation JSR 303 not recognize - spring

Question

I followed this tutorial https://springframework.guru/spring-boot-restful-api-documentation-with-swagger-2/ to generate a swagger documentation.
It's working but when I try to add some validation in my bean I don't find the information in the documentation:
#ApiOperation(value = "Creates a product",
notes="Populates a product instance bla bla")
#RequestMapping(value = "/add", method = RequestMethod.POST, produces = "application/json")
public ResponseEntity saveProduct( #Valid #RequestBody Product product){
productService.saveProduct(product);
return new ResponseEntity("Product saved successfully", HttpStatus.OK);
}
My entity with the validations annotations :
#Entity
public class Product {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
// #ApiModelProperty(notes = "The database generated product ID")
private Integer id;
#Version
// #ApiModelProperty(notes = "The auto-generated version of the product")
#NotNull
private Integer version;
// #ApiModelProperty(notes = "The application-specific product ID" )
private String productId;
// #ApiModelProperty(notes = "The product description")
#NotBlank
#Size(max = 50)
private String description;
// #ApiModelProperty(notes = "The image URL of the product")
private String imageUrl;
// #ApiModelProperty(notes = "The price of the product", required = true)
#NotNull
private BigDecimal price;
But when I check the documentation I don't have those validation information:
Here https://github.com/springfox/springfox/issues/987 they say that we need to update our dependencies and it's what I did :
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger-ui</artifactId>
<version>2.8.0</version>
</dependency>
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger2</artifactId>
<version>2.8.0</version>
</dependency>
Did I miss something in the configuration? Any idea to help me ?

I found the solution in this post : http://vojtechruzicka.com/documenting-spring-boot-rest-api-swagger-springfox/.
All is explained :
Unfortunately, JSR-303 based documentation does not work out of the box, you need an additional dependency:
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-bean-validators</artifactId>
<version>2.8.0</version>
</dependency>
And you need to import BeanValidatorPluginsConfiguration configuration file on top of your swagger configuration class:
#Configuration
#EnableSwagger2
#Import(BeanValidatorPluginsConfiguration.class)
public class SpringFoxConfig {
...
}
