Here’s another handy stuff I found on Spring MVC, if you have an unknown number of elements on your form (say a fruit basket), you can bind them into a List with @RequestParam annotation.
Let’s say this is our form:
Each text input has the same name fruits:
|
1
2
3
4
5
6 |
<form method="post"> Fruit 1: <input type="text" name="fruits"/><br/> Fruit 2: <input type="text" name="fruits"/><br/> Fruit 3: <input type="text" name="fruits"/><br/> <input type="submit"/></form> |
On your controller’s handler method, you can obtain the list of all fruit names by binding it like this:
|
1
2
3
4 |
@RequestMapping(value = "/", method = RequestMethod.POST)public String addFruits(@RequestParam("fruits") List<String> fruits) { // ...} |
The order of fruit names added to the list will be the same as the order of your form text inputs.
