UEP-查询方式总结

public void retrieve() {
    QueryParamList params = getQueryParam("dataWrap");
    //获取页面上的参数,即查询条件
    dataWrap.setDataList(uepCustomerService.retrieve(params,
    dataWrap.getPageInfo(),
    dataWrap.getSortOptions()));
    //表格(ajaxgrid):根据查询条件,查询出对应的结果集,把结果集的list放在表格的dataList里
    responseData.setAjaxDataWrap("dataWrap", dataWrap);
    //responseData里有map集合,可以把多个dataWrap传递给前台
}

public void retrieve() {
    QueryParamList params = getQueryParam("dataWrap");
    //获取前台传递过来的查询参数
//QueryParamList方法讲解
    QueryParamList params1 = new QueryParamList();
    params1.addParam("contractName","甲骨文",QueryParam.RELATION_LIKE);
    params1.addParam("id",new BigDecimal(""),QueryParam.RELATION_EQUAL);
//SortParamList(排序查询)方法讲解
    SortParamList sort = new SortParamList();
    sort.addParam("customerName",SortParam.SORT_TYPE_ASCENDING);
    sort.addParam("customerName",SortParam.SORT_TYPE_ASCENDING,"顾客");
    //顾客是别名
//JPQL
    String jpql = "select t from UepCustomer t where t.customerName like : name" ;
    //UepCustomer是UEP创建的对象名,不是数据库的表名
    QueryParamList params2 = new QueryParamList();
    Params2.addParam("customerName","甲骨文",QueryParam.RELATION_LIKE);
    List result = JPAUtil.find(jpql,params2);
    List list = new ArrayList();
    For(object o : result){
    List.add((UepCustomer)o);
    }
    dataWrap.setDataList(list);
    dataWrap.setDataList(uepCustomerService.retrieve(params1, dataWrap.getPageInfo(), sort ));
    responseData.setAjaxDataWrap("dataWrap", dataWrap);
    }
}

• 前台获取ID

function testShow(cell){
    var cid = cell["id"];    //获取主键ID
    $.showModalDialog("haiYi!doshow.do?cusId="+cid,
    "用户信息展示",null,null,400,600,0);
    //前台获取的ID传给后台定义的ID
}

• 后台通过ID查询

dataWrap.setData(demoTopicService.findById(Long.valueOf(cusId)));

UepCustomer cus=JPAUtil.loadById(UepCustomer.class, new BigDecimal(cusId));
