Please first retrieve the list from the datebase and set the list on the model attribute in the controller see the example set the 

@Controller
public class UserController {

    @RequestMapping(method = RequestMethod.GET)
    public String userHome(Model model, EventBean event, UserService userService,ImageBean image)
    {
         List<Event> events = userService.viewNews(); //retrieve the list from datebase 
                 model.addAttribute("event", event); //add bean object 
         model.addAttribute("events", events); //add list in model attribute
         return "home";
    }
}

your jsp page

<form:form modelAttribute="event"> <!--set the model attribute here -->
        <form:input path="news" value="${events.get(0).news}" />
</form:form>

I guess you are expecting something like this.

//Assumes you have the following in your class

    public class Students{
      private String name;
      private List<String> Departments;
     /* getters/setters */
    }

In the HTML would be.

    <form:input path="departments[0]" />
    <form:input path="departments[1]" />
