spring boot and html

How can I send an item from spring boot code to an html script using getmapping? i have some methods here, but on the html, all the items are hardcoded because im not sure how to get these methods on html

@GetMapping(path = "/items")
    public @ResponseBody List<Items> listItems() 
    {
        return itemsRepository.findAll();
    }

    @GetMapping(path = "/items/{id}")
    public @ResponseBody Optional<Items> findItems(@PathVariable("id") Integer id) 
    {
        return itemsRepository.findById(id);
    }

    
    @PostMapping(path = "/items")
    public @ResponseBody void addItem(@RequestBody Items item) 
    {
        itemsRepository.save(item);
    }

    @DeleteMapping(path = "/items/{id}")
    public @ResponseBody void deleteItem(@RequestParam("id") int id) 
    {
        itemsRepository.deleteById(id);
    }

@GetMapping(path = "/items")
    public @ResponseBody List<Items> listItems() 
    {
        return itemsRepository.findAll();
    }

    @GetMapping(path = "/items/{id}")
    public @ResponseBody Optional<Items> findItems(@PathVariable("id") Integer id) 
    {
        return itemsRepository.findById(id);
    }

    
    @PostMapping(path = "/items")
    public @ResponseBody void addItem(@RequestBody Items item) 
    {
        itemsRepository.save(item);
    }

    @DeleteMapping(path = "/items/{id}")
    public @ResponseBody void deleteItem(@RequestParam("id") int id) 
    {
        itemsRepository.deleteById(id);
    }

because currently we have items hardcoded onto the website, and we have the backend class for items, we just dont know how to take the methods from that class to display the items on the home page of the html

essentially, on the website we have items you can "buy" but they are hardcoded onto the html file because i am unsure as to how to make them the actual items objects from our items class on spring boot
