I am working with Spring for the first time. Right now, I have a simple HTML form to display a list of items according to some filters, just as follows:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>List of Items</title>
</head>
<body>
<form method="post" action="api/item/listItems">
<h1>Search Items</h1>
<div class="inset">
<p>
<label for="itemCode">Item Code</label>
<input type="text" name="itemCode" id="itemCode">
</p>
<p>
<label for="itemEnum">Active / No Active</label>
<input type="text" name="itemEnum" id="itemEnum">
</p>
<p>
<label for="MaxPrice">Max Price</label>
<input type="text" name="MaxPrice" id="MaxPrice">
</p>
<p>
<label for="MinPrice">Max Price</label>
<input type="text" name="MinPrice" id="MinPrice">
</p>
<p>
If you don´t complete a filter, that filter won´t be taken into account.
</p>
</div>
<p class="p-container">
<input name="submit" type="submit" value="See Items" />
</p>
</form>
<p>List of Items: ${listofitems}</p>
</body>
</html>
I also have a controler that get all the items that suits that filters:
@PostMapping("/listItems")
public String listItems(@RequestParam("itemCode") String itemCode, @RequestParam("MaxPrice") int MaxPrice, @RequestParam("MinPrice") int MinPrice, @RequestParam("itemEnum") String itemEnum, @ModelAttribute("item") Item item, ModelMap model ){
List<Item> itemList = itemRepository.findAll();
List<Item >finalItemList = new ArrayList<Item>();
if(MaxPrice == 0){
MaxPrice = 1000000;
}
for(int i=0;i<itemList.size();i++){
if(((itemList.get(i).getPrice() <= MaxPrice)&&(itemList.get(i).getPrice() >= MinPrice))){
if((itemList.get(i).getItemCode().equals(itemCode))||(itemCode.isEmpty())){
if((itemList.get(i).getItemEnum().getEstado().equals(itemEnum))||(itemEnum.isEmpty())){
finalItemList.add(itemList.get(i));
}
}
}
}
model.addAttribute("listofitems", finalItemList);
return "itemView";
}
The controller works fine. However, I don´t know how to send that list of items back to the item.html to be displayed. Right now, I added it to the model as "listofitems".
How can I achieve this? Thank you for your help!
