Presence of request param should evaluate to true
Say I have an endpoint that accepts requests as follows:
GET https://my.website.com/products?expired
OR
GET https://my.website.com/products
The method I would expect to work:
@GetMapping
public List<Product> products(@RequestParam(value = "expired", required=false) boolean expired) {
//Implementation details
}
This however, will return a Bad Request 400 response.
I know I would get this to work by sending the expired requestParam as expired=true, but I'd like for this to work similar to HTML boolean attributes where the mere presence of a request param represents true and its absence represents false

I wonder if you'll have to implement two methods, one with and one without the param, the second with it required (and probably Boolean non-primitive, as the other answer suggests).
(Then just call a common method from both.)

Use Boolean instead of boolean - the problem you have is that you are trying to unbox null value to the primitive boolean which operation causes NullpointerException and further Bad Request 400 response
public List<Product> products(@RequestParam(value = "expired", required=false) Boolean expired)
Here you can read something more about unboxing Boolean

Ok I see - I believe that what you're trying to achieve is not possible in an easy way and even if you would do this it would be misleading. You should create specific endpoint likewebsite.com/products/expiredfor your purpose or just keep on setting specifictrue/falsevalue
