BaseController

public abstract class BaseController<V extends BaseVoBean<Long, V>>{
    @RequestMapping(value = "/qry", method = RequestMethod.POST)
    @ResponseBody
    public MsgHeader<List<V>> get(@RequestBody MsgHeader<V> req) {}
}

OfferCatalogController

@Controller
@RequestMapping("/offerCatalog")
public class OfferCatalogController extends BaseController<OfferCatalogVo> {}

OfferCatalogVo

public class OfferCatalogVo extends BaseVoBean<Long,OfferCatalogVo> {}

MsgHeader

public class MsgHeader<V> {
    String  messageId;
    V       value;
}

POST 请求到 /offerCatalog/qry，请求参数为：

{"messageid":"118029","value":{}}

在 Controller 请求参数，发现 @requestbody MsgHeader req 中的 value （MsgHeader 中的 value）被解析为JSONObject，而 Jackson 会将 value 解析为 OfferCatalogVo；
