Question: I try to delete a user by getting id in url with an error:

```
Failed to convert value of type 'java.lang.String' to required type 'int'; 
nested exception is java.lang.NumberFormatException: For input string:

```

I change int id to String id, but then `deleteMyUser()` will not work because it accepts an integer.

Code:

```
<a href="/delete-user?id=${user.id}">x</a>

@RequestMapping("/delete-user{id}")
    public  String deleteUser(@PathVariable("id") int id,HttpServletRequest request)
    {   
        request.setAttribute("mode","MODE_HOME");
        userService.deleteMyUser(id);

        return "welcome";

    }

```

Answer: 
You should add the `id` to **path**, so remove `?id=`:

```
<a href="/delete-user${user.id}">x</a>

```
What about this:

```
 RequestMapping("/delete-user/{id}")

```

Use a slash between delete-user and id and then call

```
<a href="/delete-user/${user.id}">x</a>

```

Also ensure that ${user.id} contains a valid number value
