如何获取春季在表格中选择的下拉值和ID

Question

I am using Spring MVC. In my model I have a Map (say optionsMap) that will display dropdown options in UI. This is a multi selection dropdown. Id is an integer and display value is a string. On submit of form, controller should be able to get id(s) and value(s) of the selected options into a map (selectedOptionsMap).

    <form:select path="selectedOptionsMap" id="deviceList" multiple="true"></form:select>

This has already been discussed at Multiple Select in Spring 3.0 MVC . Check it out. You will need a custom editor here .
