1、
// The wrapper class, so that type info (of User) is passed thru the message converters to Jackson public class Users extends ArrayList<User> { private static final long serialVersionUID = 1L; public Users() { super(); } } // Example method from the controller: @RequestMapping(value="/status", method = RequestMethod.POST) public @ResponseBody Map<String, ? extends Object> status(@RequestBody Users users) { // handle the request here }
2、使用数组替代
3、spring 3.2 直接支持泛型集合
https://jira.springsource.org/browse/SPR-9570
sprng3.2支持如List<Sample> Map<String, Sample>等集合泛型。
