ftl页面

    <@credit.activity noActivityId=[(vo.activity.id)!] limit=[7] ;e,status>
                     <#if tdqyhnum=1>
                       <dt><a href="${e.url!''}"><img src="${resourceDomain}${e.shortImage!''}" alt=""></a><span><a href="${e.url!''}">${e.title!''}</a></span>${e.description!''}</dt>
                     <#else>
                        <dd><span><#if e.expireTime??>${e.expireTime?string("yyyy-MM-dd")}<#else>长期有效</#if></span><a href="${e.url!''}" title="">${e.title!''}</a></dd>
                     </#if>
                     <#assign tdqyhnum=tdqyhnum+1>
        </@credit.activity>

<@credit.activity noActivityId=[(vo.activity.id)!] limit=[7] ;e,status>表明调用credit标签中的activity方法传递的参数是noActivityId

于是找到了

标签调用controller中的findpage方法于是去找 ftlCreditActivityService

于是找到了

@Service
public class FtlCreditActivityService implements FtlService {

   private static final Logger LOG = LoggerFactory.getLogger(FtlCreditActivityService.class);
   @Autowired
   CreditActivityApiService creditActivityApiService;

   public Page<CreditActivityRestResult> findPage(List<Number> activityId, List<Number> noActivityId,
           List<String> flag, List<String> noFlag, List<Number> tagId, List<String> keyword, String orderBy,
           Boolean random, List<Number> limit, List<Number> storeId, List<Number> bankId, List<Number> screeningId,
           List<Number> regionId, List<Number> creditcardId, Long isSelf) throws Exception {
       CreditActivityParam creditActivityParam = new CreditActivityParam(activityId, noActivityId, flag, noFlag,
               tagId, keyword, orderBy, random, limit, storeId, bankId, screeningId, regionId, creditcardId, isSelf);
       @SuppressWarnings("unchecked")
       List<CreditActivityRestResult> list = (List<CreditActivityRestResult>) creditActivityApiService.findList(
               creditActivityParam).getDefaultModel();
       Page<CreditActivityRestResult> page = new Page<CreditActivityRestResult>();
       page.setResult(list);
       return page;
   }

}

用CreditActivityRestResult 来封装各类参数

调用findList

--solr部分

@Service

   @Autowired
   HttpSolrServer httpSolrServer;
   @Autowired
   ActivityDao activityDao;

           } catch (SolrServerException e) {
               return new CreditApiResult(false);
           }
       }
       result.setDefaultModel(activitysort);

       return result;
   }

   private List<CreditActivityRestResult> findByDb(List<Number> activityId) {

       }
       List<CreditActivityRestResult> creditActivityRestResults = new CreditActivityRestResult()
               .getRestResults(activityDao.findByIds(getIdsFromRes(res)));
