/*** * <p>Description：查找作业记录</p>* <p>Paramenter：</p>* <p>Return：</p>* <p>Exception：</p>* <p>Modified History: </p>*/public String getHomeworkList(){if(firstQuery){//如果是第一次查询则设置查询时间queryTime = System.currentTimeMillis();}QueryPage queryPage = new QueryPage(pageSize,pageIndex,null,null);queryPage.addEqualSearch("userId",super.getCurrentUserId());queryPage.addEqualSearch("state", state);queryPage.addAliasLessEqualSearch("homework", "a", "createTime", new Date(queryTime));queryPage.addAliasSort("homework", "a", "createTime", "desc");homeworkRecordViewVoList = homeworkBiz.getHomeworkList(queryPage, state);//设置分页信息String pageUrl = "/homework/getHomeworkList.action";pageBean = new PageBean(queryPage.getTotalRows(), queryPage.getPageIndex(), queryPage.getPageSize(), pageUrl);String pageBeanParamters = "queryTime="+queryTime+"&firstQuery=false&state="+state;pageBean.setParamters(pageBeanParamters);return state;}
