UEP-自定义持久化类
HY-UEP提供了两种持久化方式:基于JPA的持久化机制和自定义持久化机制,JPA的持久化机制
比较符合现在的软件开发模式,支持各种主流数据库;自定义持久化时我们平台产品的特有持久化
机制的升级,在综合查询、大数据量处理以及快速开发方面比较有优势,两者各有千秋,业务开
发人员可根据自身项目情况和具体功能选择使用。
自定义持久化包括结果集和DBTool
--添加自定义持久化类
Propertier-UEP-开发平台-Add 生成xml文件
--DataSet下
- Query DataSet Root:一项可配置查询结果集文件的路径
- Proc DataSet Root:一项可配置存储过程结果集文件的路径
- Proc Mapping Root:一项可配置存储过程映射的路径
--配置demo.xml(=framework.xml)
--action中AjaxDataSetAction
package com.haiyisoft.bill.other.action; import java.math.BigDecimal; import java.util.List; import org.apache.struts2.convention.annotation.Action; import org.apache.struts2.convention.annotation.Namespace; import org.apache.struts2.convention.annotation.ParentPackage; import org.apache.struts2.convention.annotation.Result; import com.haiyisoft.ep.framework.ui.struts2.action.AjaxAction; import com.haiyisoft.ep.framework.ui.struts2.action.AjaxDataSetAction; import com.haiyisoft.ep.common.model.QueryParamList; import com.haiyisoft.ep.framework.ui.struts2.model.AjaxDataSetWrap; import com.haiyisoft.ep.framework.ui.struts2.model.AjaxDataWrap; import com.haiyisoft.ep.framework.bizservice.AutowireService; import com.haiyisoft.ep.log.LogUtil; import com.haiyisoft.entity.UepCustomer; import com.haiyisoft.bill.component.service.TcService; /** * UepCustomer维护 * * @author LENOVO * * <p>Modification History:</p> * <p>Date Author Description</p> * <p>------------------------------------------------------------------</p> * <p>2017-12-7 LENOVO 新建</p> */ @Namespace("/other") @ParentPackage("framework-default") @Action(value = "/uepCustomerDS", results = {@Result(name="input",location="uepCustomerDS.jsp")}) public class UepCustomerDSAction extends AjaxDataSetAction { private static final long serialVersionUID = 1L; @AutowireService private TcService tcService; private AjaxDataSetWrap dataWrap = new AjaxDataSetWrap(); /** *查询操作 */ @Override public void retrieve() { Object[] params = new Object[1]; params[0] = new BigDecimal(4); dataWrap.retrieve(params);
//结果集带参数
//dataWrap.retrieve();
//结果集不带参数 responseData.setAjaxDataWrap("dataWrap", dataWrap); } /** *初始化 */ @Override protected void initTreat() { super.retrieveAfterInit = true ; //dataWrap.setDsName("queryCustomer"); dataWrap.setDsName("queryCustomerById");
//添加结果集 this.dataWrap.getPageInfo().setRowOfPage(15); } @Override public AjaxDataSetWrap getDataWrap() { return dataWrap; } public void setTcService(TcService tcService) { this.tcService = tcService; } public TcService getTcService() { return tcService; } }
--jsp中name只能为数据库中的字段名
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <%@ include file="/framework/include/pageset.jspa"%> <script type="text/javascript" src="uepCustomerDS.js"></script> <html> <head> <title>UepCustomer维护</title> </head> <body> <hy:view> <s:form action="uepCustomerDS"> <hy:layoutTable> <hy:layoutArea> <hy:ajaxgrid id="ajaxgrid" name="dataWrap" height="100%" width="100%" queryfunc="retrieve()"> <hy:gridlineno title="序号" width="30" /> <hy:gridcheckbox name="checked" width="50" title="全选" /> <hy:gridfield name="ID" title="ID" width="100" regexpmessage="只能为数字" maxlength="12" required="true" regexp="^\d*$" /> <hy:gridfield name="CUSTOMER_NAME" title="客户名称" width="100" required="true" maxlength="64" /> <hy:gridfield name="REMARKS" title="备注" width="100" maxlength="128" /> </hy:ajaxgrid> </hy:layoutArea> </hy:layoutTable> </s:form> </hy:view> </body> </html>
--DBTool
public void retrieve(){ /*QueryParamList params = getQueryParam("dataWrap"); List<UepContract> list = uepCustomerService.retrieve(params, dataWrap.getPageInfo(), dateWrap.getSortOptions()); dataWrap.setDataList(list); responseData.setAjaxDataWrap("dataWrap", dataWrap);*/ String sql = "select * from uep_customer"; List<Object> params = new ArrayList<Object>(); DBTool[] tool = new DBTool(); Reocrd[] records = tool.executeQuery(sql,params,dataWrap.getPageInfo()); //Record序列化成UepCostomer实体 List<UepCustomer> dataList = tool.executeQuery(UepCostomer.class, sql,params,dataWrap.getPageInfo()); dataWrap.setDataList(dataList); responseData.setAjaxDataWrap("dataWrap",dataWrap); }
