springmvc @RequestBody绑定泛型集合

1、

http://ahlearns.wordpress.com/2011/07/29/spring-3-mvc-requestbody-deserialization-of-custom-list-objects/

// 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。
