wex5和nutz集成，前端wex5，后端nutz

今天用wex5解决数据维护的需求，需求比较简单，订单数据的查询、新增、删除、更新。

功能界面见下图

2. wex5的代码片段，主要是data组件的两个事件orderDataCustomRefresh、orderDataCustomSave

orderDataCustomRefresh

	Model.prototype.orderDataCustomRefresh = function(event){
		var searchVal = this.getElementByXid("searchInput").value;
		var dfd =$.Deferred();
		var doRefresh =function(event,dfd){
			justep.Baas.sendRequest({
				"url" : "/ecoolper/order",
				"action" : "queryAction",
				"async" : true,
				"params" : {
					"searchVal" : searchVal,
					"limit" : event.limit,
					"offset" : event.offset
				},
				"success" : function(table) {
					event.source.loadData(table,event.options.append);
					dfd.resolve();
				}
			});
			return dfd.promise();
		}(event,dfd);
		event.promise =$.when(doRefresh);
	};

orderDataCustomSave

	Model.prototype.orderDataCustomSave = function(event){
		var dfd =$.Deferred();
		var doSave =function(event,dfd){
			justep.Baas.sendRequest({
				"url" : "/ecoolper/order",
				"action" : "saveAction",
				"async" : true,
				"params" : {
					table : event.source.toJson(true)
				},
				"success" : function(data) {
					dfd.resolve();
				}
			});
			return dfd.promise();
		}(event,dfd);
		event.promise =$.when(doSave);
	};

这里用到了jquery的Deferred特性，5.2版本是没有这个特性的。

x5 studio的设计界面

3. nutz后端后端用的baaServer做的改造，BaasServer工程在runtime目录下，先把BaasServer工程导入到studio中，再做改造。

后端主要用到OrderAction的两个方法query、saveAction

query

	@At("/queryAction")
	@Ok("json")
	@AdaptBy(type = JsonAdaptor.class)
	public JSONObject query(@Param("..") JSONObject params) {
		Integer limit = params.getInteger("limit");
		Integer offset = params.getInteger("offset");
		String searchVal =params.getString("searchVal");
		Cnd cnd = Cnd.NEW();
		if(Strings.isNotBlank(searchVal)){
			searchVal ="%"+searchVal+"%";
			cnd.or("userName","like", searchVal);
			cnd.or("phoneNumber", "like",  searchVal);
			cnd.or("address", "like", searchVal);
			cnd.or("content", "like", searchVal);
		}

		int pageNumber = (int) Math.ceil(offset / limit) + 1;
		Pager pager = new Pager();
		pager.setPageNumber(pageNumber);
		pager.setPageSize(limit);
		List<Order> rows = dao.query(Order.class, cnd, pager);
		// 设置总个数
		pager.setRecordCount(dao.count(Order.class, cnd));

		JSONObject table = new JSONObject();
		table.put("@type", "table");// 设置type
		table.put("rows", rows);// rows
		JSONObject userdata = new JSONObject();
		userdata.put("sys.count", pager.getRecordCount());
		table.put("userdata", userdata);// 设置userdata
		return table;
	}

saveAction

	@At("/saveAction")
	@AdaptBy(type = JsonAdaptor.class)
	@Aop(TransAop.READ_COMMITTED)
	public void saveAction(@Param("..") JSONObject params) throws ParseException {
		Table table = Transform.jsonToTable(params.getJSONObject("table"));
		// 更新
		List<Order> list = Transform2.tableToPojo(table, RowState.EDIT, Order.class);
		dao.update(list, DataUtils2.arrayJoin4Regex(table.getColumnNames().toArray(), "%s", "|"));
		// 添加
		list = Transform2.tableToPojo(table, RowState.NEW, Order.class);
		dao.insert(list);
		// 删除
		list = Transform2.tableToPojo(table, RowState.DELETE, Order.class);
		dao.delete(list);
	}

DataUtils2类

public class DataUtils2 {

	public static String arrayJoin4Regex(Object[] objects, String format, String separator) {
		StringBuffer buf = new StringBuffer();
		buf.append("^(");
		for (Object o : objects) {
			if (buf.length() > 0) {
				buf.append(separator);
			}
			buf.append(String.format(format, o.toString()));
		}
		buf.append(")$");
		return buf.toString();
	}
	
}

Transform2

public class Transform2 {
	public static <T> List<T> tableToPojo(Table table, RowState state, Class<T> type) {
		List<T> list = new ArrayList<>(); // 存放转换结果
		// 先得到所有字段名称
		Collection<String> names = table.getColumnNames();
		// 开始遍历row
		for (Row row : table.getRows(state)) {
			Map<String, Object> map = new HashMap<String, Object>();
			for (String name : names) {
				map.put(name, row.getValue(name));
			}
			T t = Lang.map2Object(map, type);
			list.add(t);
		}
		return list;
	}
}
