Spring, the average score in the request parameter

Question

Is there a way to map the query parameter to the average score using queries in spring?

I have no problems with binding to single-partition parameters:

Uri example: http://localhost:8080/test/?product=hotels

public class CitiesRequest{
    private ProductType product;

    public ProductType getProduct() {
        return this.product;
    }

    public void setProduct(String product) {
        this.product = product;
    }
}

But I would like to receive such parameters:

http://localhost:8080/test/?product-type=hotels

Answer 1

By default, Spring maps the request parameter key to the name of the Java variable. However, it is syntactically incorrect to have a variable name with a hyphen in Java, which explains why it is especially difficult for you to get Spring to set the parameter value for you.
