RequestBody绑定泛型集合

// 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  
    }
