如果您的
User对象有一个
id字段，则可以这样提交所选用户的ID（在这种简单情况下，您甚至不需要Spring的form标记）：
<form ...> <c:foreach var = "user" items = "${users}"> <input type = "checkbox" name = "userIds" value = "${user.id}" checked = "checked" /> <c:out value = "${user.firstName}" /> ... </c:foreach> ...</form>-
@RequestMapping (...)public void submitUsers(@RequestParam(value = "userIds", required = false) long[] userIds){ ...}
