@RequestMapping(value = "/listByUserId")
public PageInfo<Product> listByUserId(User user) {
    
}

What I am receiving is a User object, in which the User attribute id, I want to set an initial value for it, that is, there is an initial value when the id parameter is not sent. I use @RequestParam to specify the id attribute defalutValue, but it does not work. Is there any way to achieve this? It is best not to change to the User class

This is what I wrote:

@RequestMapping(value="/student/{st_no}",method= RequestMethod.GET)
public Student info(@PathVariable Integer st_no){
}
