YbSoftwareFactory 的 最新 ASP.NET MVC 插件所生成的项目目前支持组织机构管理和菜单权限管理功能,如下将简单介绍其实现的部分核心代码。 1、组织机构管理的实现 组织机构管理采用 Provider 模式实现,使用 ADO.NET 进行数据访问,如下是 Provider 实现类中的初始化方法,从中可看出,通过在config文件中指定tableName可以自由定义对应的表名称,默认情况下为表的名称为 YbOrganizations 表。
#region Initialize
public override void Initialize(string name, System.Collections.Specialized.NameValueCollection config) { // Validate arguments if (config == null) throw new ArgumentNullException("config"); if (string.IsNullOrEmpty(name)) name = "YbOrganizationProvider"; if (String.IsNullOrEmpty(config["description"])) { config.Remove("description"); config.Add("description", "Yb organization provider"); } if (String.IsNullOrEmpty(config["tableName"])) { config.Remove("tableName"); config.Add("tableName", "YbOrganizations"); } // Initialize base class base.Initialize(name, config); // Read connection string this.ConnectionStringName = config.GetConfigValue("connectionStringName", null); if (string.IsNullOrWhiteSpace(this.ConnectionStringName)) throw new ConfigurationErrorsException(Resources.Required_connectionStringName_attribute_not_specified); this.connectionStringSetting = ConfigurationManager.ConnectionStrings[this.ConnectionStringName]; if (this.connectionStringSetting == null) throw new ConfigurationErrorsException(string.Format(Resources.Format_connection_string_was_not_found, this.ConnectionStringName)); if (string.IsNullOrEmpty(this.connectionStringSetting.ProviderName)) throw new ConfigurationErrorsException(string.Format(Resources.Format_connection_string_does_not_have_specified_the_providerName_attribute, this.ConnectionStringName)); //激发设置连接字符串前的事件处理程序,主要目的是解密连接字符串 ConnectionStringChangingEventArgs args = RaiseConnectionStringChangingEvent(connectionStringSetting.ConnectionString); if (args == null) throw new ProviderException(Resources.Connection_string_cannot_be_blank); if (!this.connectionStringSetting.ConnectionString.Equals(args.ConnectionString)) { this.connectionStringSetting = new ConnectionStringSettings(this.ConnectionStringName, args.ConnectionString, this.connectionStringSetting.ProviderName); } if (string.IsNullOrEmpty(this.connectionStringSetting.ConnectionString)) throw new ProviderException(Resources.Connection_string_cannot_be_blank); this.applicationName = config["applicationName"]; this.tableName = config["tableName"]; SecUtility.CheckParameter(ref tableName, true, true, true, 256, "tableName"); } #endregion
我们可以通过Web API发布组织机构管理的有关接口,这样JQuery EasyUI的前端界面在展示和管理数据时能更加得心应手,同时这些接口还能通过WinForm客户端、WPF客户端,其他Web应用程序及各种类型的智能手机客户端访问,可谓一举N得,呵呵。如下是Web Api相应Controller的核心代码实现:
// GET api/item/id
public Organization Get(Guid id) { string key = string.Format(CacheKeyList.ORGANIZATION_BY_KEY,id); return _cacheManager.Get(key, () => { var item = OrganizationApi.GetOrganization(id); return item; }); } // POST api/item public HttpResponseMessage Post(Organization item) { item.DisplayOrder = OrganizationApi.GetMaxDisplayOrder()+1024d; item.CreatedBy = User.Identity.Name; OrganizationApi.CreateOrganization(item); var msg = new Message(true, "数据添加成功") { data = item }; var response = Request.CreateResponse(HttpStatusCode.Created); var uri = Url.Link("DefaultApi", new { id = item.OrganizationId }); response.Headers.Location = new Uri(uri); response.Content = new StringContent(msg.ToString(), Encoding.UTF8); return response; } // PUT api/item/id [System.Web.Http.HttpPost] [System.Web.Http.HttpPut] [System.Web.Http.AcceptVerbs("POST", "PUT")] public HttpResponseMessage Put(Guid id, Organization item) { item.LastUpdatedBy = User.Identity.Name; OrganizationApi.UpdateOrganization(item); //移除缓存 _cacheManager.Remove(string.Format(CacheKeyList.ORGANIZATION_BY_KEY, item.OrganizationId)); var msg = new Message(true, "数据保存成功") { data = item }; var response = Request.CreateResponse(HttpStatusCode.OK); response.Content = new StringContent(msg.ToString(), Encoding.UTF8); return response; } // DELETE api/item/id public HttpResponseMessage Delete(Guid id) { OrganizationApi.HardDeleteOrganization(id); //移除缓存 _cacheManager.Remove(string.Format(CacheKeyList.ORGANIZATION_BY_KEY, id)); return new HttpResponseMessage(HttpStatusCode.NoContent); } }
最终实现的界面效果图如下,可以方便的排序和升降级:
组织机构的编辑界面如下:
2、菜单权限管理的实现 YbRapidSolution for MVC的权限项分为面板、菜单和按钮三类,顶层菜单被默认为分组面板并在左边的导航区域块标题中显示,同时每个分组面板还支持树形结构菜单。首先来看看界面效果(和组织机构管理一样,可以方便地通过右键菜单实现排序和升降级):
在JQuery EasyUI的Tree中,每个子节点需要一个名称为 _parentId 的属性,而顶层节点则不能包含这个属性,否则你是无法在JQuery EasyUI中显示出树形结构的(如果你的程序始终无法显示出树形结构,则很可能就是这个原因)。如下是权限子项的模型类,供需要的童鞋参考:
public class ChildPermissionModel : PermissionModel
{ public ChildPermissionModel(Permission permission) : base(permission) { } public object _parentId { get { return this.ParentPermissionKey; } } } 添加菜单项的界面效果如下:
通过“点击选择图标”按钮可以很方便地选择和管理菜单导航图标。而下图则是添加按钮的界面效果图:
在JQuery EasyUI中要实现右键菜单功能其实是非常容易的,最后,附上JQuery EasyUI的行右键菜单的实现代码,一切就是这么简单,继续供需要的童鞋参考:
function createRowContextMenu() {
var tmenu = $('<div ></div>').appendTo('body'); $('<div iconCls="icon-goup"/>').html('上移').appendTo(tmenu); $('<div iconCls="icon-godown"/>').html('下移').appendTo(tmenu); $('<div iconCls="icon-arrowleft"/>').html('升级').appendTo(tmenu); $('<div iconCls="icon-arrowright"/>').html('降级').appendTo(tmenu); tmenu.menu({ onClick: function (item) { if (item.iconCls == 'icon-goup' || item.iconCls == 'icon-godown') { var isUp = item.iconCls == 'icon-goup'; $.ajax({ url: virpath + '/Organization/UpdateDisplayOrder?id=' + curRowData.OrganizationId + '&isUp=' + isUp, type: 'Post', datatype: 'application/json; charset=utf-8', error: function (result) { Msgalert('错误', '操作失败:' + result, 'error'); }, success: function (result) { //result为请求处理后的返回值 result = result.replace(/\\/g, ''); result = eval('(' + result + ')'); if (result.success) { $.messager.show({ title: '成功', msg: result.msg, timeout: 2000, showType: 'fade' }); grid.treegrid('reload'); } else { Msgalert('错误', result.msg, 'error'); } } }); } else if (item.iconCls == 'icon-arrowleft' || item.iconCls == 'icon-arrowright') { var isLeft = item.iconCls == 'icon-arrowleft'; $.ajax({ url: virpath + '/Organization/UpdateLevel?id=' + curRowData.OrganizationId + '&isUp=' + isLeft, type: 'Post', datatype: 'application/json; charset=utf-8', error: function (result) { Msgalert('错误', '操作失败:' + result, 'error'); }, success: function (result) { //result为请求处理后的返回值 result = result.replace(/\\/g, ''); result = eval('(' + result + ')'); if (result.success) { $.messager.show({ title: '成功', msg: result.msg, timeout: 2000, showType: 'fade' }); grid.treegrid('reload'); } else { Msgalert('错误', result.msg, 'error'); } } }); } } }); }
在下个版本中,我们将实现一个可非常方便进行调用的自定义 Setting 管理类,能非常方便地处理应用程序中的各种配置信息。 最后附个在线 Demo 地址:http://mvcdemo.yellbuy.com/。 |
