手动添加模糊查询

public void retrieve() {
    QueryParamList params = getQueryParam("dataWrap");
    QueryParam param = params.get("contractName");
    if(param!=null){
    param.setRelation(QueryParam.RELATION_LIKE);
    param.setValue("%"+param.getValue+"%");
    dataWrap.setDataList(uepCustomerService.retrieve(params,dataWrap.getPageInfo(),dataWrap.getSortOptions()));
    responseData.setAjaxDataWrap("dataWrap", dataWrap);
}
