CRUD

需求:表格增删改查的前后端框架搭建


背景:

在日常的系统开发中,表格(Grid)是最常见的数据表达形式,而表格中增删改查又是最常见的功能之一。所以在日常的开发选中,快速的构建表格增删改查的框架将大大的加速开发者的效率。

此次SpreadJS V15所推出的集算表功能就是专门用来应对这样的场景

那么如何快速搭建带有集算表的前后端增删改查框架呢,下面将按照步骤一步步进行拆解

解决方案:

1、后端使用Spring Boot做快速搭建,创建一个spring boot web工程,下面是大致用到的dependencies

121731zcja5a6c38y4pvcu

基本除了springboot自带的之外,额外引用了fastjson用于对一些复杂json格式进行处理。


2、构建前后台,可以选择前后端分离,或者结合的方式(例子中选中了前后端结合的方式),大致工程结构如下:

3、构建前端页面,前端页面的可以选择适合的框架(VUE,React,Angular,例子中使用源生JS进行构建),在页面中引入SpreadJS TableSheet(集算表)中的相关依赖

121845klmezbhxlv8nxb5n

需在原本SpreadJS的依赖基础上引入gc.spread.sheets.tablesheet这个依赖。


4、构建前端集算表配置配置集算表的功能操作

var myTable = dataManager.addTable("myTable", {
  remote: {
    read: {
      url: "initDataManager",
    },
    batch: {
      url: "batchUpdateDataManager",
    },
  },
  batch: true,
  autoSync: false,
});

上述配置了读取和批量两个操作,读取设置是在指定地址下读取数据。而批量操作包含对数据的批量增删改。从而覆盖到整个增删改查逻辑。

var rowActions = GC.Spread.Sheets.TableSheet.BuiltInRowActions;
var options = sheet.rowActionOptions();
options.push(rowActions.removeRow, rowActions.saveRow, rowActions.resetRow);
sheet.rowActionOptions(options);

上述代码设置了页面上供用户进行操作的对应按钮(删除行,保存行,重置行)

myTable.fetch().then(function () {
  var view = myTable.addView("myView", [
    { value: "id", caption: "编号", width: 80 },
    { value: "firstname", caption: "姓", width: 100 },
    { value: "lastname", caption: "名", width: 100 },
    { value: "homephone", caption: "电话", width: 100 },
  ]);
  sheet.setDataView(view);
});

上述代码设置了表格的结构,对每一列进行了设置

var submitButton = document.getElementById("submit");
submitButton.addEventListener("click", function () {
  sheet.submitChanges();
});

通过设置一个提交的按钮,用于将批量的修改进行一次性提交。


5、后端构建对应的数据增删改查逻辑(实例中通过一个假数据构建一个list进行模拟,实际情况可以扩展持久层与真实的数据库进行交互)。

private static List<Employee> list = new ArrayList<Employee>();
static {
    for (int i = 0; i < 10; i++) {
        Employee employee = new Employee();
        employee.setId(i);
        employee.setFirstname("FirstName" + i);
        employee.setLastname("LastName" + i);
        employee.setHomephone("HomePhone" + i);
        list.add(employee);
    }
}

@RequestMapping(value = "/initDataManager", method = RequestMethod.GET) @ResponseBody
public List<Employee> initWorkBook () {
    return list;
}

@RequestMapping(value = "/batchUpdateDataManager", method = RequestMethod.POST) @ResponseBody
public List<Map<String, Object>> batchUpdateDataManager (@RequestBody List < BatchManager > batchManagerList) {
    List<Map<String, Object>> reutrnList = new ArrayList<Map<String, Object>>();
    for (BatchManager batchManager : batchManagerList) {
        Map<String, Object> returnMap = new HashMap<String, Object>();
        String type = batchManager.getType().toString();
        try {
            if (type.equals("update")) {
                Employee employee = batchManager.getDataItem();
                int index = batchManager.getSourceIndex();
                Employee employeeSource = list.get(index);
                employeeSource.setId(employee.getId());
                employeeSource.setFirstname(employee.getFirstname());
                employeeSource.setLastname(employee.getLastname());
                employeeSource.setHomephone(employee.getHomephone());
                list.remove(index);
                list.add(index, employeeSource);
                returnMap.put("succeed", true);
            } else if (type.equals("insert")) {
                Employee employee = batchManager.getDataItem();
                list.add(employee);
                returnMap.put("succeed", true);
                employee.setId(employee.getId() + 10000);
                returnMap.put("data", employee);
            } else if (type.equals("delete")) {
                int index = batchManager.getSourceIndex();
                list.remove(index);
                returnMap.put("succeed", true);
            }

        } catch (Exception e) {
            returnMap.put("succeed", false);
        }
        reutrnList.add(returnMap);
    }
    return reutrnList;
}

这样,我们的框架就算搭建完成了。后面可以根据情况再做细微的调整和优化。总共耗时30分钟左右。

实例的代码可以参考附件,有兴趣的朋友可以下载自行参考搭建DataManager.zip
