Delete Field Spring MVC - spring-mvc

Question

I am using SimpleFormController with a result page looking like this:
<tr>
<td>Name: </td>
<td>${product.name}</td>
</tr>
<tr>
<td>Text: </td>
<td>${product.text}</td>
</tr>
A user can enter a name and some text. I'm trying to implement a delete functionality for each entry (there should be a link next to each entry). I'm having trouble with understanding, if it can be done in the same Controller as for the input or not (am new to Spring) and how. The onSubmit method helps to display data that was added, do I need to implement an extra delete method? If yes, how can I "map" it to my delete link in my jsp?

Answer 1

I suppose you are not wanting to put a delete link even when the user is just entering the name!
Delete links should normally appear when you are displaying data, not creating them.
Here is how you can create a delete link according to associated ids.
<tr>
<td>Name: </td>
<td>${product.name}</td>
<td>delete</td>
</tr>
and this should be in your controller:
#Controller
public class ProductController{
#RequestMapping("/delete/{id}")
public String deleteProduct(#PathVariable("id")Integer id) {
// get product by id
// delete that product
// save database
// or do as you wish
return "redirect:/index";
}
}
Hope that helps :)
